戴尔 Precision M4700 Mobile 工作站测评
Mobile workstations are in a class of their own, and are not widely represented in the market. Along with their powerful performance, good ergonomics and comprehensive configuration possibilities, the other features that stand out as important are reliability, the provided service and compatibility. The extended warranty periods and the long-term availability of replacement parts alone drive up prices. The Dell Precision M4700 is the new version of the M4600, whereby the new edition is also only available at a price starting from 1199 Euros (~$1546) plus VAT. One thing that remains constant is the 15.6-inch display, which provides a resolution of 1920x1080 pixels with a 16:9 aspect ratio. Dell hereby distinguishes between an average panel and a guaranteed premium panel.
One reason for the elevated price segment, apart from the aforementioned reasons, is surely the integrated components. The model tested by us had an up-to-date Intel Core i7-3720QM quad-core processor with vPro support, a special NVIDIA Quadro K2000M graphics card with 2 GB of GDDR3 memory, 16 GB of RAM and 256 GB of SSD memory. This configuration already costs over 3000 Euros (~$3869) in the online store. The pinnacle of performance and price still hasn’t been reached yet though. Depending on preference and budget, the notebook is also available with an Intel Core i7-3920XM (619 Euros/~$798 extra), 32 GB of RAM, or an additional docking station. On the other end of the spectrum are the more affordable versions with Intel Ivy Bridge dual-core processors and NVIDIA Quadro K1000M. Read about what has changed, and which advantages and disadvantages this workstation provides in this review.
For the sake of comparison we also received a second more affordable version of the Dell Precision M4700. This variant is equipped with an Intel Core i7-3520M and an AMD FirePro M4000 graphics card. A corresponding comparison of the two configurations was also carried out during the review.
移动工作站是在他们自己的类，而不是在市场上有广泛代表性的。随着其强大的性能，良好的人体工程学设计和全面的配置的可能性，站出来为重要的其他功能，可靠性，所提供的服务和兼容性。延长保修期和长期可用性更换部件的单独哄抬价格。戴尔Precision M4700是新版本的M4600，在新的版本也只适用于从1199欧元（〜$1546），另加增值税的价格。有一件事是不变的是15.6英寸的显示屏，它提供了宽高比为16:9，分辨率为1920×1080像素。戴尔在此区分的平均面板和优质面板保证。
价格段升高的一个原因，除了上述原因，肯定是集成组件。该模型进行测试，我们有一份最新的英特尔酷睿酷睿i7-3720QM四核处理器，支持博锐，一个特殊的NVIDIA®（英伟达™）Quadro K2000M显卡，2 GB GDDR3内存，16 GB的RAM和256 GB的SSD存储器。这种配置已经花费超过3000欧元（〜$3869），在网上商店。 ，性能和价格的巅峰之作仍然没有达到，但。根据不同的喜好和预算，笔记本电脑也可以与英特尔酷睿i7-3920XM（619欧元，/〜798美元额外），32 GB的RAM，或额外的停靠站。在另一端的频谱与英特尔Ivy Bridge的双核处理器和NVIDIA®（英伟达™）Quadro K1000M更便宜的版本。了解发生了什么变化，它的优点和缺点，这工作站提供在本次审查。
为了便于比较，我们还收到了第二个更实惠的版本的戴尔Precision M4700。这种变异配备了英特尔酷睿i7-3520M和AMD的FirePro M4000显卡。在审评过程中的两个配置也进行了相应的比较。
Case
The earthy brown case color has been kept by Dell and hasn't been changed. It makes a high quality and robust impression thanks to the materials used. One point of criticism of the identically constructed Dell Precision M4600 was the loose battery. In the case of the reviewed model, this now sits firmly in the case, whereby one of the four feet is still located on the battery. When using the workstation without this, it is no longer possible to guarantee the stability of the device. When considering the combined weight of the device, one thing that stands out is that the new model is now 280 grams (0.62 pounds) heavier with the same battery. With a total weight of 3.44 kilograms (7.58 pounds) and its hefty dimensions, the M4600 is unlikely to be a daily guest in your briefcase. One reason for the clunky look is also the straight line design of the chassis. Rounded edges and slanted surfaces usually make notebooks look slimmer.
土褐色的颜色一直保持的情况下，戴尔并没有被改变。它使高品质和强大的印象，由于所用的材料。有一点批评的结构完全相同的戴尔Precision M4600的电池松动。在审查模式的情况下，现在坐在坚决的情况下，其中的四个支脚仍位于电池。当使用没有这个工作站，它不再是可能的，以保证设备的稳定性。当考虑到该设备的总重量，脱颖而出的一件事是，新的模式是现在使用同样的电池重280克（0.62磅）。总重量为3.44公斤（7.58磅），其沉重的尺寸，M4600是不太可能在你的公文包每天的客人。的原因之一笨重的外观设计的底盘也是直线。圆润的边角和倾斜的表面通常使笔记本电脑看起来更苗条。
Connectivity
The positioning and quantity of interfaces have not changed with the new model either. All around the notebook there is a multitude of interfaces available, which live up to the requirements of a professional device. HDMI, USB 3.0 and a card reader already belong to the standard repertoire of almost all notebooks these days. A little more special is an eSATA USB combination, FireWire 1394, a docking port hub on the bottom, a slot for an ExpressCard (54 millimeters), or a SmartCard reader.
Looking at the case a few small changes are noticeable. For instance, there is now a slot-in DVD drive on board, and the 2.5-inch drive bay on the right side is now labeled. For a more rounded impression, Dell could have also provided this model with a Thunderbolt port and FireWire 800 integrated. A Blu-ray drive is available as an option in the online store. The additional cost of 511 Euros (~$659) plus VAT is however on the excessive side. Further details regarding the interfaces can be found in the review of the Dell Precision M4600.
与新模型的接口的定位和数量并没有改变。笔记本电脑周围有众多的接口，可生活的要求的专业设备。 HDMI，USB 3.0和一个读卡器已经属于标准的剧目几乎所有的笔记本电脑，这些天。有一点比较特别的是一个eSATA USB组合，一个ExpressCard插槽（54毫米），1394火线，一个对接端口集线器的底部，或智能卡阅读器。
纵观一些小的变化是明显的情况下。举例来说，现在有一个插槽在DVD驱动器上板，和2.5英寸驱动器托架的右侧标记。带来更完美的印象，戴尔还提供了一个Thunderbolt端口和FireWire 800集成这种模式与。一个蓝光驱动器是可用的网上商店中的一个选项。然而，过度的额外成本为511欧元（约$659），另加增值税。有关接口的更多细节，可以发现，在审查的戴尔Precision M4600。
Communication
When it comes to the communications features no wish is left unfulfilled, whereby the features can be selected according to preference. Our reviewed sample supports the current wireless technologies in the form of WLAN standards 802.11 a/b/g/n (Intel Centrino Ultimate-N 6300 AGN) and Bluetooth 4.0. The latter of which is located directly next to the battery and can be reached quickly. Hard-wired Gigabit communication is also performed with the help of an Intel module. The corresponding socket is located at the back of the device, which should help to avoid cables getting in each other’s way. A UMTS module is offered by Dell for 134 Euros (~$173) plus VAT. The matching antennae are already included as standard. Upgrading retrospectively is therefore not a difficult task.
Security
Security features are obligatory in the professional field, or in any enterprise in which sensitive data is handled. The device itself provides a fingerprint reader for this purpose, as well as a Trusted Platform Module (TPM), a SmartCard reader, and various password options. For bigger companies Intel vPro, which is provided in conjunction with the processor, could also come in handy. Using this, IT staff can for example access system information, configure or change the system, or switch the system on or off remotely. These features are titled "Intel Active Management Technology" (AMT). Dell in addition also provides other Value-Added-Services. Among these are backup, data destruction and recovery functions, as well as Anti-Theft markings.
Accessories
The accessories included with this back to basics device are within the usual scope. Along with the workstation itself, we were also able to find a 97 Watt-hour battery, a 180 Watt AC adapter, some documentation, two software DVDs and a recovery DVD. Further additions have to be purchased separately. As for the docking station port, Dell provides several solutions which are available starting from 58 Euros (~$75). The extended Dell E-Port II with a 130 Watt PSU and USB 3.0 at the other end of the scale costs 169 Euros (~$218). As far as the pre-installed software is concerned, Dell is more or less providing a completely clean install. Along with the system and proprietary tools, there is merely a test version of Trend Micro (15 months) installed.
Maintenance
One area of criticism with the Precision M4600 was that some of the components were relatively difficult to access. The base plate also serves as a large maintenance panel in this case, which can be slid open after removing the battery and two screws. Even though the processor and graphics card may still not be immediately accessible, the other relevant components are.
Underneath the base plate are the two banks for DDR3 RAM, a socket for the mSATA SSD tested by us which could also be used for a UMTS module, one free socket for a half-size card, and two directly accessible cooling fans. These can be easily removed and cleaned. The 2.5 inch drive is located towards the side, and is attached by four screws. A further screw secures the latching mechanism in position. Once all the screws are removed, the storage device can be replaced while the device is switched on (hot swap). In order to release the latching mechanism the battery has to be removed first though. In this case a direct access solution would have been preferable.
Warranty
A simple warranty option of only 12 months is not available with this class of device. Dell provides the Precision M4700 with a warranty period of 36 months including next day on-location service. For an additional sum, this service can be upgraded to the so called ProSupport. The time period covered is also 36 months in this case (217 Euros/~$280), or even 60 months for 651 Euros (~$840) (RRP).
通讯
当涉及到的通信功能不希望留下未完成的，可以根据个人喜好选择的功能。我们覆检了抽样支持当前的形式WLAN标准802.11 A / B /克/ N（英特尔®迅驰®旗舰版-N 6300 AGN）和蓝牙4.0无线技术。后者位于电池旁边，可以达到迅速。硬连线千兆通信也与一个Intel模块的帮助下进行。相应的插槽位于设备背面，这将有助于避免电缆在对方的方式。一个UMTS模块的Dell所提供的134欧元（约$ 173），另加增值税。匹配的触角已经作为标准配置。因此，升级追溯是不是一项艰巨的任务。
安全
在专业领域，或在任何企业在处理敏感数据的安全功能是必须的。该设备本身提供了用于此目的的指纹读取器，以及一个可信平台模块（TPM），一个智能卡阅读器，以及各种密码选项。对于大公司的英特尔博锐处理器的结合，也可以派上用场了。 IT人员可以利用这一点，例如访问系统信息，配置或更改系统，或将系统切换开启或关闭远程。这些功能“英特尔主动管理技术”（AMT）。戴尔此外还提供其他增值服务。其中包括数据备份，数据的破坏和恢复功能，以及防盗标记。
饰品
这回基本设备的配件包括通常的范围内。随着工作站本身，我们也能找到一个97瓦小时电池，180瓦AC适配器，一些文件，两个软件DVD和恢复DVD。进一步增加，必须单独购买。至于扩展坞端口，Dell提供了几种解决方案，是从58欧元（约75美元）。扩展的Dell E-一个130瓦电源和USB 3.0端口II在另一端的规模，费用为169欧元（约$ 218）。至于预装软件方面，戴尔或多或少是提供一个完全干净的安装。随着系统以及专有工具，仅仅是一个测试版趋势科技（15个月）安装。
保养
批评精密M4600的一个领域是，一些组件相对难以访问。底板也作为一个大的维护面板，在这种情况下，它可以滑动打开，取出后的电池和两个螺钉。即使处理器和图形卡可能无法立即访问，其他相关部件。
的底板下方的mSATA SSD的插座进行了测试，我们也可以用于一个UMTS模块，一个自由插座的一半大小的卡片，DDR3内存，和两个冷却风扇直接访问两个银行。这些可以被容易地除去和清洗。 2.5英寸驱动器位于朝向一侧，并用四个螺钉固定连接。进一步的螺丝固定位置的闩锁机构。一旦所有的螺丝被删除，存储设备，而手机处于开机状态，可以更换（热插拔）。为了释放的闩锁机构，第一，虽然电池已被删除。在这种情况下，将有一个直接存取溶液是优选的。
保
一个简单的只有12个月的保修选项是不可用此类设备。戴尔的Precision M4700提供的保修期为36个月，包括第二天定位服务。对于额外款项，这项服务可以升级到所谓的专业技术支持。涵盖的时间段是36个月，在这种情况下，（217欧元/〜$ 280），甚至60个月为651欧元（约$ 840）（建议零售价）。
Input Devices
With the exception of the fact that the previously reviewed Dell Precision M4600 ran through our test course with an American QWERTY keyboard layout, nothing has changed as far as the input devices are concerned. Dell once again opts for a pleasant keyboard with backlight, as well as the combination touchpad and Pointstick plus the corresponding mouse buttons. Details regarding these features can be found in the aforementioned review.
随着先前评论的戴尔Precision M4600跑了一个事实，即通过我们的测试当然与美国的QWERTY键盘布局的异常，并没有改变尽可能输入设备有关。戴尔再次选择了一个愉快的带背光的键盘，以及触摸板和指点杆的组合加上相应的鼠标按键。关于这些功能的详细信息，可以发现在上述审查。
Display
When it comes to the display, Dell offers different variants with a diagonal length of 15.6-inches. The lowest qualitative option in this case is a panel with a resolution of 1366x768 pixels, which we tested with our entry-level comparison device with AMD graphics. Aside from this inappropriate resolution for this segment, the measured characteristics also failed to impress. In light of the intended target market, likely only a Full-HD panel would be the right solution. In this case there are two different models to choose from. One of these is a very high quality RGB display, which is meant to cover a large portion of the reference color space. The display tested by us is a more simple FHD display, with a resolution of 1920x1080 pixels, and an aspect ratio of 16:9. Thanks to the IPS technology, the viewing angle stability is maximized. In the online store Dell distinguishes between a normal display, and a "Premium Panel Guarantee". This high quality panel mentioned previously uses RGB LEDs.
For connecting an external display the workstation provides multiple possibilities: VGA for older displays and projectors, as well as HDMI and DisplayPort.
Starting off, the first of our measurements taken with the panel (type LDG0303) is the provided brightness, which is measured using the Gossen-Mavo-Monitor tool. On average our reviewed model achieves a value of 217 cd/m², and thus lies in the mid-range. Similar values are also provided by more affordable office notebooks. Interestingly the "normal" FHD panel with the Dell Precision M4600 was significantly brighter, something that represents a clear step backwards in this area. In contrast to this we were impressed by the even illumination across the whole panel, which led to an impressive value of 93 percent.
当涉及到显示器，戴尔提供了不同的变种，对角线长度为15.6英寸。在这种情况下，最低定性的选择是一个面板，分辨率为1366×768像素，这是我们入门级的比较器与AMD图形测试。除了这个不当的分辨率为这个段，测得的特性也没能留下深刻的印象。根据预定的目标市场，可能只有全高清面板，将是正确的解决方案。在这种情况下，有两种不同的型号可供选择。其中之一是一个非常高的质量，其目的是要覆盖一个大的部分的基准色空间的RGB显示器。我们所测试的显示是一个更简单的FHD显示，与分辨率为1920×1080像素，并且纵横比为16:9。由于IPS技术，使视角稳定性最大化。在戴尔的网上商店区分正常显示，和“完美面板保证”。前面提到的这种高品质的面板采用RGB LED的。
连接外接显示器的工作站提供了多种可能性：较大的显示器和投影机的VGA以及HDMI和DisplayPort。
从一开始，我们的测量的面板（类型LDG0303）采取的是所提供的亮度，这是衡量使用的Gossen公司MAVO监视器工具。平均而言，我们的审查模式实现了价值217坎德拉/平方米，位于中档。类似的数值也提供了更实惠办公的笔记本。有趣的是，“正常”的FHD面板与Dell Precision M4600是显着光明的，代表一个明确的倒退，在这方面的东西。与此相反，我们留下了深刻的印象，甚至照明在整个面板，这导致了一个令人印象深刻的93％。

74.6% sRGB (Argyll 2.2.0 3D)
61% Display P3 (Argyll 2.2.0 3D)
The further measurements left a good impression: The black level lies at 0.35 cd/m², whereby a saturated black can be presented. Leading on from this the contrast ratio is correspondingly high as a result. The value of 597:1 reached is especially noticeable when presenting movies, pictures and graphics, or when the notebook is used outdoors. The representable color space isn't able to fully impress on the other hand: The standard FHD panel with our reviewed device unfortunately doesn't completely cover the sRGB color space. Compared to the larger Adobe RGB color space there is therefore still even more missing. In this context the optional high quality RGB display should be helpful. The Lenovo ThinkPad W530 as a direct competitor offered a significantly better color space performance compared to our reviewed device.
进一步的测量，留下了很好的印象：黑电平位于0.35坎德拉/平方米，由此可以呈现饱和的黑色。领导从这个对比度是作为结果相应的高。达到597:1的值是呈现电影，图片和图形，或当笔记本在户外使用时，尤其明显。表现的色彩空间是不能够充分留下深刻的印象，另一方面，不幸的是，标准FHD面板，我们审查的设备并不能完全涵盖sRGB色彩空间。相比较大的Adobe RGB色彩空间，因此更失踪。在这方面，可选的高品质RGB显示的应该是有帮助的。联想ThinkPad W530作为直接的竞争对手相比，我们的审查设备提供了一个更好的色彩空间表现。
During outdoor use the matte display surface and the brightness of over 200 cd/m² plus the high contrast ratio pay off. In the shade, working is easily possible and there are barely any limitations. Under direct sunlight reading the display is slightly affected. A higher brightness, such as that provided by the M4600, would be beneficial in this case. All in all it is nevertheless still a good display, even for people who occasionally work outdoors in sunny weather.
在户外使用的雾面显示屏表面和超过200 cd /m²的亮度，加上高对比度还清。在树荫下，工作是很容易的，几乎没有任何限制。在直射阳光下阅读的显示略受影响。较高的亮度，如由M4600提供，在这种情况下，将是有益的。所有的一切，它是仍然不错的显示效果，即使是在阳光明媚的天气偶尔在户外工作的人。
The viewing angle stability doesn't leave any wishes unfulfilled thanks to In-Plane Switching (IPS). Both in the horizontal and vertical planes the image remains stable throughout. A clearly noticeable loss of brightness, or a changing color temperature wasn't visible. Especially affordable TN panels have to contend with this issue. Altogether an expectedly good performance from the Precision M4700 in this respect.
不留任何希望未实现板内切换（IPS）的视角稳定。无论是在水平和垂直平面的图像保持稳定。清晰醒目的损失的亮度，或改变色温是不可见的。特别是经济实惠的TN面板有抗衡这个问题。共有的Precision M4700在这方面的预期的良好表现。
Performance
Under the hood of our reviewed device thoroughly high quality and especially high performance components can be found. The heart of the device is the Intel Core i7-3720QM quad-core processor from the current Ivy Bridge family, which is made using the 22 nanometer manufacturing process. With a basic clock speed of 2.6 GHz and a maximum Turbo Boost of a whole 3.6 GHz, this chip operates in the upper part of our test database, as can be seen in our CPU benchmark list. Furthermore there is also an NVIDIA Quadro K2000M professional graphics card with 2 GB of GDDR3 RAM. Compared to the consumer GPUs from the GeForce family, the Quadro family models are specially optimized for CAD applications. In this case 16 GB of DDR3 RAM, as well as an mSATA SSD and conventional hard drive combination round off the whole package.
The memory devices as well as the rest of the components can be configured as required in Dell's online store, whereby there is only one bay for a 2.5-inch drive available. One change compared to the Dell Precision M4600 is the exclusive use of NVIDIA graphics. The processor graphics unit Intel GMA HD 4000 is deactivated in this system, and cannot be used with the automatic switching provided by NVIDIA Optimus.
根据我们的审阅设备全面的高品质，特别是高性能的组件的引擎盖上都可以找到。的设备的心脏是Intel酷睿i7-3720QM四核处理器，从目前的Ivy Bridge的家庭，这是用22纳米制造工艺。有了一个基本的时钟速度为2.6 GHz，最大睿频加速3.6 GHz的整体，该芯片工作在我们的测试数据库的上半部分，可以看出，在我们的CPU基准测试列表。此外，还有NVIDIA®（英伟达™）Quadro K2000M专业图形卡2 GB GDDR3 RAM。给消费者的GeForce GPU（图形处理器）的家庭相比，Quadro系列的机型是专门为CAD应用程序进行了优化。在这种情况下，16 GB的DDR3内存，以及一个有mSATA SSD和传统硬盘驱动器的组合四舍五入全包。
存储设备以及其他组件可以根据需要进行配置，在戴尔的网上商店，其中有只有一个托架，用于一个2.5英寸驱动器。一个变化相比，戴尔Precision M4600的独家使用NVIDIA®（英伟达™）图形。在这个系统中的处理器的图形单元英特尔GMA HD4000被停用，并且不能使用与由NVIDIA擎天柱提供的自动切换。
Processor
At the beginning of our testing are the usual CPU benchmarks. The Intel Core i7-3720QM doesn't have to be shy, and secures itself top positions in our database. The multithread calculations with CineBench R11.5 (64-bit) are completed with 6.82 points, and with wPrime(1024M) the system needs 351 seconds.
The Lenovo ThinkPad W530 as a direct competitor was equipped with the somewhat faster Intel Core i7-3820QM in our test. With CineBench this resulted in 6.94 points. The difference of only two percent is certainly very marginal. Looking back to the predecessor of our reviewed device, a difference of 15 percent in favor of the newer model emerges in this case. The Dell Precision M4600 had an Intel Core i7-2920XM on board.
Altogether the M4700 is well equipped with the tested processor, since the additional cost of 251 Euros (~$324) doesn't present an excessive price. The Intel Core i7-3920XM which is also available belongs among the extreme-processors from Intel, and is likely only interesting for performance aficionados that are willing to pay any price for the maximum performance. The additional cost associated with this, compared to the basic model with an Intel Core i5-3320M, lies at a staggering 1126 Euros (~$1452) plus VAT.
在开始我们的测试通常是CPU的基准。英特尔酷睿i7-3720QM不害羞，并保护自己的最高职位，在我们的数据库中。 CINEBENCH R11.5（64位）的多线程计算6.82点，完成，和的wPrime（1024M）系统需要351秒，。
作为一个直接的竞争对手联想ThinkPad W530配备了几分速度更快的英特尔酷睿i7-3820QM在我们的测试中。通过CINEBENCH这导致了6.94点。只有2％的差异肯定是非常边缘。回顾我们的审查设备的前身，两者相差15％赞成新的模式，在这种情况下出现。戴尔Precision M4600有一个英特尔酷睿i7-2920XM板。
共M4700配备的测试处理器的额外费用为251欧元（约$324），因为不存在一个过度的价格。英特尔酷睿i7-3920XM，也可属于英特尔处理器之间的极端，很可能只是有趣的性能爱好者，愿意付出任何代价的最高性能。与此相关的额外成本相比，英特尔酷睿i5-3320M的基本模式，是达到了惊人的1126欧元（〜$1452），另加增值税。
System Performance
The performance provided by the whole package, and the subjective impression are an important point - who wants to get held up by eternal waiting times these days? The system benchmarks from FurMark provide a good point of reference in this respect. With PCMark 7 for example, the M4700 reaches an impressive result of 4647 points. Comparative results were achieved by the slim Lenovo ThinkPad X1 Carbon and the Schenker XMG P722 PRO. The Solid State Drive tested by us makes a significant contribution to the good rating of the system performance. For this reason the upper third of the test database also contains several Ultrabooks with a power saving CPU.
Subjectively there are no wishes unfulfilled: The system quickly boots up, loading times are minimal, and delays hardly ever occur. A closer look in this respect is taken at the latencies with Windows 7. The DPC Latency Checker shows that most values are within the green area, even when the WLAN module is active. When a download is running simultaneously though, then clear spikes into the red area are visible, and the values are generally increased. A known problem is the crackling of audio from external sound cards when the latencies get too high.
提供全包，和主观印象的表现是很重要的一点 - 谁想要得到永恒的等待时间，这些天？从FURMARK的系统基准测试在这方面提供了很好的参考点。使用的PCMark 7例如，M4700达到令人印象深刻的4647点的结果。比较的结果是实现了超薄联想ThinkPad X1碳和全球国际货运代理XMG P722 PRO。固态驱动器的测试，我们作出了显着贡献的良好评级的系统性能。出于这个原因的上三分之一处测试数据库还包含几个Ultrabooks具有节电CPU。
主观上有没有愿望未了：该系统迅速启动时，加载时间是微乎其微的，而延迟几乎没有发生。再仔细一看在这方面采取的延迟与Windows 7。 DPC延迟检查表明大多数的值是在绿色区域内，即使当WLAN模块处于激活状态。 ，然后当下载同时运行，但明确的尖峰进入红色区域是可见的，并普遍增加值。一个已知的问题是噼里啪啦的声音从外部声音卡时的延迟太高。

Battery Powered Performance
While battery-powered the Dell Precision M4600 was unable to reach the full performance that is available when the power lead is connected. For this reason we performed various benchmarks with the verdict that the new M4700 also has this problem to contend with. The CPU results however remain on a consistent level, and only the performance of the GPU isn't able to be fully utilized. Using the OpenGL calculations from CineBench R11.5 results in a difference of 12 fps. This corresponds to a performance deficit of 30 percent. Similarly the rating by 3DMark 06 also results in a difference of 28%, with 8667 points compared to 11965. Considering the results compared to those of its predecessor, Dell hasn't been able to improve in this respect.
虽然电池供电的Dell Precision M4600是无法达到的电源线连接时，可以使用的全部性能。为此，我们进行了不同的基准，新的M4700也有这个问题，以抗衡对判决结果。然而，CPU结果保持在一致的水平，并只有在GPU的性能是不能够得到充分的利用。使用OpenGL的计算CINEBENCH R11.5结果，相差12 fps的。这相当于30％的性能赤字。 3DMark 06的等级也同样结果的差为28％，与8667点相比为11965。考虑的结果，其前身相比，戴尔一直没能

CAD Performance
The tool SPEC ViewPerf 11 uses the most popular CAD applications and measures the achieved frame rates. The configuration with the Intel Core i7-3720QM combined with the professional NVIDIA Quadro K2000M is able to make a good impression in this case. The older Precision M4600 is significantly outperformed in almost all the tests. The percentage difference meanwhile lies at up to 25 percent, depending on the application. The Lenovo ThinkPad W530 with the same graphics card and a more powerful processor meanwhile performs on more or less the same level in most tests. A further comparison can also be made to the weaker M4700 model, with an AMD FirePro M4000 GPU. The difference works in favor of the NVIDIA GPU in some cases, while working in favor of the AMD GPU in other cases, depending on the program. CAD users should consider their individual software in this case, and should test this if in doubt.
On the whole the M4700 provides an impressive performance, which can only be improved upon by bigger mobile workstations. Dell for example also provides the Precision M6700 with an NVIDIA Quadro K5000M in this case.
工具规格的Viewperf11采用了最流行的CAD应用程序和措施所取得的帧速率。配置上采用英特尔酷睿i7-3720QM结合NVIDIA®（英伟达™）Quadro专业K2000M是在这种情况下，能留下一个好印象。旧的精密M4600显着跑赢大市，几乎所有的测试。同时的百分比差异在于在高达25％的，根据不同的应用。联想ThinkPad W530相同的图形卡和一个更强大的处理器，同时执行上或多或少在大多数测试中相同的水平。较弱的M4700模型进行进一步的比较还可以，与AMD的FirePro M4000 GPU。在支持的NVIDIA GPU在某些情况下，不同的工作，而工作在AMD GPU赞成在其他情况下，根据该计划。 CAD用户应该考虑自己的个人软件，在这种情况下，如有任何疑问，应该测试。
整体而言，M4700提供了一个令人印象深刻的表现，只能加以改善的更大的移动工作站。戴尔还提供了例如精密M6700在这种情况下，NVIDIA®（英伟达™）Quadro K5000M。

Mass Storage
A large 2.5-inch hard drive, a smaller one with 7200 revolutions per minute, a Solid State Drive, or a combination of both technologies? Dell provides countless possibilities in its online store for configuring the M4700. Our reviewed device has a 2.5-inch hard drive from Western Digital which functions as a mass storage device. This provides a total capacity of 1 TB, with a speed of 5400 revolutions per minute. Thus this model does not belong among the fastest solutions. This was also confirmed by our benchmarks below.
As system memory there is also an additional mSATA SSD (Solid State Drive, 256 GB) from Samsung on board though. Thanks to the SATA III connectivity and its capacity, the model from the 830 series certainly doesn't have to be shy. With values between 230 and 260 MB/s (AS SSD) this is a quick solution, which scores primarily due to fast access times. Full grown 2.5-inch SSDs, such as the OCZ Vertex 4, can easily reach the 500 MB/s mark with sequential operations though, and are definitely worth considering. In the end it remains a question of the requirements and the available budget.
宽大的2.5英寸硬盘驱动器，一个7200转每分钟，固态硬盘，或这两种技术的结合？在其网上商店配置的M4700，戴尔提供了无数的可能性。我们的审查器件具有一个2.5英寸的硬盘西部数据（Western Digital）作为大容量存储设备的功能。这提供了一个总容量为1 TB，每分钟5400转的速度。因此，这种模式不属于世界上速度最快的解决方案。这也证实了我们的基准以下。
作为系统内存也有一个额外的mSATA SSD（固态驱动器，256 GB）三星虽然在船上。由于SATA III连接，其容量从830系列，模型肯定不会有害羞。随着230和260 MB/秒（AS SSD）之间的值，这是一个快速的解决方案，这分数，主要是由于快速的访问时间。全部增长了2.5寸固态硬盘，比如OCZ的顶点，可以很容易地达到500 MB/ s的标记虽然与顺序操作，是绝对值得考虑。最后，它仍然是一个问题的要求，并在可用的预算。
Graphics Card
In this section the NVIDIA Quadro K2000M has to contend with the synthetic gaming benchmarks from FurMark. With the tried and tested 3DMark 06 using a resolution of 1280x1024 pixels the GPU achieved a good result of 11965 points. Due to optimizations GeForce graphics units have an advantage. The Lenovo ThinkPad W530 is in the immediate neighborhood. Apart from this the K2000M positions itself among the segment of current mid-range graphics units in diverse multimedia notebooks. The smaller Schenker XMG A102 subnotebook with an NVIDIA GeForce GT 650M is also within touching distance. The AMD FirePro M4000 which was also tested by us outperforms the NVIDIA alternative achieving 14172 points (difference: 18%). This is a good performance from both tested graphics units in this area, but gaming should be left to other devices, even if it is definitely possible with the mobile workstation.
在本节中，NVIDIA®（英伟达™）Quadro K2000M从FURMARK抗衡的合成游戏测试。尝试和测试的3DMark 06测试采用了一块分辨率为1280x1024像素的GPU实现了11965分的好成绩。由于优化的GeForce图形单元是有优势的。联想ThinkPad W530是近邻。除了这K2000M目前中档图形单位间段在不同的多媒体笔记本电脑。全球国际货运代理，XMG A102亚笔记本电脑的NVIDIA GeForce GT650M也内感人的距离。 AMD的FirePro M4000这也是我们测试优于NVIDIA的替代，达到14172分（差：18％）。这是从两个测试的图形单位在这方面有着不错的表现，但的游戏应该留给其他设备，即使它是绝对有可能的移动工作站。

Gaming Performance
A short gaming check and the comparison between the NVIDIA Quadro K2000M and the AMD FirePro M4000 shouldn't be left out at this stage. Both GPUs reach frame rates on the level of current mid-range graphics units in normal notebooks. Both models operate in the region of the previously mentioned GeForce GT 650M, whereby the variant from AMD at least manages to eke out an advantage when it comes to Anno 2070 and Battlefield 3. This slight performance enhancement had already been noticed during the gaming benchmarks.
It is worth stating that a mobile workstation is surely the wrong device for gamers. For prices upwards of 1500 Euros (~$1935) there are significantly more powerful systems available with suitable graphics cards. Professional solutions on the other hand are aimed at other application areas.
短NVIDIA®（英伟达™）Quadro K2000M和AMD的FirePro M4000游戏检查和比较，不应该被排除在这个阶段。这两个GPU（图形处理器）达到的水平，目前中档普通笔记本电脑的图形单位的帧速率。这两种机型可在该地区的前面提到的GeForce GT650M，从AMD的变种至少设法维持一个优势，当谈到纪元2070和战地3。这种轻微的性能提升已经注意到，在游戏测试。
它值得说明的是，移动工作站为游戏玩家肯定是错误的设备。对于价格超过1500欧元（〜$1935）有更强大的系统提供合适的图形卡。专业的解决方案的另一方面的目的是在其他的应用领域

Emissions
System Noise
"Never change a running system." This statement is well suited to the cooling system in the workstation. Already the M4600 was able to provide a good impression with two cooling fans combined with heat pipes. In our case the cooling fans are also accompanied by a hard drive, which also represents a source of noise. With a measured value of 31 dB(A) this is hardly audible. During office use the notebook operates quietly throughout, and merely the unobtrusive humming of the HDD can be heard. Swapping the storage device for a modern Solid State Drive would also cause this noise to be prevented.
With a high processing load the device makes itself noticeable. With noise measurements between 42.6 and a clearly audible 48.1 dB(A), this can become annoying over time. The low frequency noise emitted by the cooling fans, as well as the quick reduction of speed, are both advantages. Compared to the predecessor the cooling fans now seem to react much more quickly in order to keep the hardware well acclimatized. With a medium operating load we were only able to measure 36.6 dB(A) with the Precision M4600, whereby a difference of 10 dB(A) corresponds to a subjective doubling of the volume.
系统噪声
“永远不要改变正在运行的系统。”此语句以及适合在工作站中的冷却系统。已经M4600是两个冷却风扇与热管相结合，能够提供一个良好的印象。在我们的例子中，也伴随着硬盘驱动器，这也代表了一个噪声源的冷却风扇。随着测量值的31分贝（A），这是几乎听不见。在办公室使用笔记本电脑操作安静贯穿始终，只是不显眼的嗡嗡声可以听到硬盘驱动器。交换的存储设备为一体的现代化固态硬盘也将导致要防止这种噪声。
较高的处理负载设备，使自己明显。随着噪声的测量在42.6和清晰可闻48.1分贝（A）之间，这可以成为恼人随着时间的推移。发出的低频噪音的散热风扇，以及迅速减少的速度，这两个优势。冷却风扇的前身相比似乎反应更迅速，以保持良好水土不服的硬件。中等工作负载，我们只能够，来衡量36.6分贝（A）的Precision M4600，相差10分贝（A）对应于一个主观的体积增加一倍。

Temperature
Dell provides different performance profiles with Windows 7, which have names like "Cold" (reduced temperatures) or "Ultra Performance". Depending on use, these profiles can be used, or additional settings can be selected. In an idle state the top surface of the keyboard stays pleasantly cool throughout. The bottom heats up to a lukewarm maximum of 39.6 degrees Celsius, which doesn't pose a problem.
With a high processing load the bottom of the case reaches a maximum of 55.5 degrees Celsius. Subjectively the heat is clearly noticeable, whereby the mobile workstation will likely be primarily used on a desk. Compared to the M4600 the successor now gets about six degrees warmer on the bottom. This could be the result of the combination of more powerful hardware and a tried and tested cooling system. Altogether the values stay within limits for this device and performance class, and don't get to a critical level.
The subject throttling is literally a hot topic with this professional device. Nevertheless after a full hour of our stress test (FurMark + Prime95) there are still no thermal problems. The processor clock speed reduces slightly to 3.2 GHz with four active cores over time. In an ideal scenario 3.4 GHz should be provided with maximum Turbo in this case. Changing to the power profile "Ultra Performance" created by Dell doesn't change this either. A matching BIOS update could possibly make a difference. Our reviewed device had version A01 running.
戴尔提供不同的性能特征与Windows 7，其中有名称，如“冷”（降低温度）或“超性能”。根据用途，这些公司可以使用，或可以选择附加设置。在空闲状态下的顶面的键盘保持凉爽各地。底部加热冷淡最大摄氏39.6度，这并不构成问题。
具有高的处理负载的底部的情况下达到最大为55.5摄氏度。主观上的热量显然是明显的，有可能被主要用于移动工作站的桌子上。相对于M4600的继任者获得约6度的底部温暖。这可能是更强大的硬件和一个尝试和测试的冷却系统的组合的结果。共值留在此设备的性能等级的限制，并没有得到一个临界水平。
受限制是名副其实的热门话题，与本专业设备。我们的压力测试，但经过整整一个小时的FurMark+ Prime95的仍然有不热的问题。该处理器的时钟速度略有降低至3.2 GHz，随着时间的推移有四个活动的核心。在理想情况下，应提供3.4 GHz的，在这种情况下，最大睿频可达。更改为功率曲线“超性能”由戴尔不会改变。匹配的BIOS更新可能有所作为。我们审查的设备版本A01运行。
(±) The maximum temperature on the upper side is 42.1 °C / 108 F, compared to the average of 38.2 °C / 101 F, ranging from 22.2 to 69.8 °C for the class Workstation.
(-) The bottom heats up to a maximum of 55.5 °C / 132 F, compared to the average of 41.3 °C / 106 F
(±) In idle usage, the average temperature for the upper side is 32 °C / 90 F, compared to the device average of 32 °C / 90 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (33.9 °C / 93 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (-6.1 °C / -11 F).
Speakers
The speakers located above the keyboard deliver an acceptable audio quality. Even mid-range and lower frequencies as well as bass can be represented to a certain extent, despite the quality not being as good as high quality speakers or headphones. The maximum volume is more than sufficient, whereby the sound starts to distort at the limit. This is a good result for this class of device without any big surprises, since the system was already familiar to us from the M4600.
位于键盘上方的扬声器提供可接受的音频质量。即使是中档和较低的频率以及低音可以在一定程度上表示，尽管质量不高品质扬声器或耳机。的最大体积是超过足够的，从而使声音开始扭曲在极限。这一类的设备，没有任何大的意外，这是一个很好的结果，因为系统已经为我们所熟悉的M4600。
Battery Life
Power Consumption
The power consumption is certainly an important criterion for mobile devices in this day and age. Thus the processor for example only operates at 1.2 GHz in an idle state (SpeedStep), whereby power is saved. In an idle state the M4700 uses between 21.1 and 34.4 Watts. The Lenovo ThinkPad W530 however has an efficiency advantage thanks to the use of the graphics integrated into the processor. The minimum power consumption with this configuration lies at 11.4 Watts. The maximum consumption during office use lies at 20.9 Watts, which is approximately equivalent to the entry value of the M4700, meaning that the reviewed device has higher power consumption in a device class comparison.
With a high processing load there are only marginal differences between the two workstations. With a maximum of 130 Watts the power consumption lies within the boundaries in the tested configuration. The included AC adapter is also sufficiently dimensioned. It provides a maximum performance of 180 Watts, which also leaves enough spare capacity. Depending on the buyers wishes Dell also delivers the M4700 with a 65, 87 or 97 Watt-hour battery. We had the biggest version for 99 Euros (~$128) for the test.
耗电量
在这一天，年龄的移动设备的功耗无疑是一个重要的标准。因此，例如处理器只能工作在1.2 GHz处于闲置状态（SpeedStep动态节能），电源被保存。在空闲状态下的M4700采用21.1和34.4瓦之间。联想ThinkPad W530但是，由于使用的图形集成到了处理器的效率优势。在于这个配置的最低功耗为11.4瓦。在办公室使用的最大消费是20.9瓦，这大约相当于在M4700的入账价值，也就是说，审查设备的设备类中比较具有较高的功耗。
较高的处理负载有两个工作站之间只有微小的差异。最大130瓦的功耗范围内的测试配置中的边界。附带的AC适配器也有足够的尺寸。它提供了最大180瓦的性能，也留下了足够的备用容量。根据购房者希望戴尔还提供了M470065，87或97瓦小时的电池。我们有最大的为99欧元（约128美元）的测试版本。

Battery Runtime
The battery runtime is decent, even if the ideal results during office use are missing the internal graphics in the CPU. The Reader Test tool from Battery Eater simulates the reading of text documents with the minimum display brightness, deactivated wireless modules, and the maximum power saving functions enabled. After a good 6 hours and 23 minutes the power has to be reconnected in this scenario. The opposite scenario is tested using the Classic Test, whereby the system is used with the maximum brightness and wireless modules activated. The large battery provides a battery life of 82 minutes in this case.
The measurement "surfing via WLAN" represents a realistic measurement without the power connected. With 150 cd/m² of display brightness different websites are loaded every 40 seconds. After around three hours this came to an end.
电池的使用时间是体面的，即使在办公室使用的理想的结果是缺少内部CPU的图形。从电池食阅读器测试工具模拟阅读的文本文件的最低显示亮度，禁用无线模块，最大省电功能启用。一个好6小时23分钟后，在这种情况下，要重新连接电源。与此相反的情况下进行测试，使用经典的测试，从而使系统一起使用的最大亮度和无线模块激活。大容量电池提供了82分钟，在这种情况下的电池寿命。
“通过WLAN上网的测量”是指一个实际的测量无连接的电源。拥有150 cd /m²的亮度不同的网站显示加载每40秒。约三小时后，走到了尽头。
Verdict
The Dell Precision M4700 mobile workstation is built on a tried and tested chassis. Many positive aspects were able to be reconfirmed during the course of the review, and could be attested to as being good. Among these are for example the robust case, the comprehensive connectivity and the cooling system.
The high price and the limited mobility are no novelty either. The missing graphics switching for better energy efficiency, and the slight throttling of the GPU when battery-powered, are all big disadvantages.
As far as the performance is concerned there isn't really any cause for criticism. The combination of an up-to-date Intel Core i7-3720QM quad-core processor with an NVIDIA Quadro K2000M graphics card is perfectly suited to CAD applications. Depending on the budget and wishes, the workstation can be more or less configured exactly as required in the online store. From the simplest entry-level device for 1200 Euros (~$1548), right up to the most powerful configuration for in excess of 4000 Euros (~$5159), everything is possible. A look at various online retailers without the Dell configuration options can be worth it due to the many pre-configured systems.
戴尔Precision M4700移动工作站是建立在一个经得起考验的底盘。许多积极的方面是能够重新确认在审查过程中，可能会被证明为好。其中有例如强劲的情况下，全面的连接和冷却系统。
高昂的价格和有限的流动性是没有新意。丢失的显卡切换功能，更好的能源效率，和轻微的GPU节流电池供电时，都是大的缺点。
至于表现而言，有没有真正的批评的任何原因。跟上时代的英特尔酷睿i7-3720QM四核处理器与NVIDIA®（英伟达™）Quadro K2000M显卡的组合非常适合于CAD应用程序。根据预算和愿望，工作站可多可少的配置完全相同，需要在网上商店。从最简单的入门级设备为1200欧元（1548年），一直到超过4000欧元（〜$5159）最强大的配置，一切都是可能的。一看没有戴尔的配置选项，可以在不同的网上零售商是值得的，由于许多预配置系统。
