惠普 Pavilion g7-2007sg 笔记本测评
The HP Pavilion g7 series covers the whole gamut: a price search lists up to thirty different models of the versatile multimedia notebook - covering the low end to upper middle class and everything in-between.
After evaluating two of the less expensive models with AMD's Trinity APU (g7-2053sg with A6-4400M and g7-2051sg with A10-4600M) in the last few weeks, we decided to take a look at the most powerful member of the series - the g7-2007sg. This model retails for over 700 Euro and features a speedy Intel Core i7-3612QM, 8 GB RAM, and a 750 GB hard drive. The Radeon HD 7670M should offer enough performance for gaming, although the card might have some issues with the native resolution of the 17-inch display (1600 x 900 pixels).
Of course, other manufacturers offer models competing in the same bracket. Possible alternatives are the Lenovo G780, Dell Inspiron 17R-SE , and the Acer Aspire V3-771G (depending on the configuration). Let's see if HP's model is able to differentiate itself from its competition.
惠普Pavilion G7系列覆盖了整个域的价格搜索，列出了30种不同型号的多功能的多媒体笔记本 - 覆盖低端到中上层阶级和一切都在两者之间。
评估两个较便宜的型号与AMD的三位一体的APU（G7-2053sg A6-4400M和G7-2051sg A10-4600M）在过去的几个星期后，我们决定在了最强大的成员，该系列一起来看看 - 的G7-2007sg。这种模式的零售价为700欧元和功能迅速的英特尔酷睿i7-3612QM，8 GB RAM，和一个750 GB的硬盘驱动器。 Radeon HD7670M的应提供足够的游戏性能，，虽然卡可能有一些问题的原始分辨率的17英寸显示屏（1600 x 900像素）。
当然，其他制造商提供的模型在同一方括号内的竞争。可能的替代方案是联想G780，戴尔Inspiron17R-SE，和宏基的Aspire V3-771G（取决于配置）。让我们来看看HP的模型能够从竞争中脱颖而出。
Case
The chassis of the Pavilion g7-2007sg is made of black plastic and is identical to the the AMD version. Unfortunately, that's not a plus point: the highly reflective and rather cheap looking piano finish is a dirt magnet and requires frequent cleaning. Rigidity and overall sturdiness could use some improvement as well: both the display and the base unit don't resist twisting forces well and protest with an occasional creaking sound. Two positive aspects are the fairly low weight of under 3 kilogram (6.61 pounds) and the - at least for our test sample - decent build quality.
To be fair though: depending on the components, the Pavilion g7 can be had for about 400 Euro on up. Considering this price range, the quality is acceptable and not much different from other (and similar) models. For an in-depth look at the chassis please check the review of the g7-2051sg.
底盘的亭G7-2007sg的黑色塑料是相同的AMD版本。不幸的是，这是不是加点：高反射率和相当便宜的钢琴烤漆是土磁铁，需要经常清洗。刚度和整体的坚固性，可以使用一些改善，以及显示和基本单元没有很好的抗扭曲力和抗议，一个偶然的吱吱嘎嘎的声音。两个积极的方面是相当低的重量在3公斤（6.61磅） - 至少在我们的测试样机 - 体面的建设质量。
为了公平起见，虽然根据的组成部分，展馆G7，在多达约400欧元就可以了。考虑到这个价格范围内，质量是可以接受的，并没有太大的不同（及类似）模型。对于在机箱的深入了解，请查看G7-2051sg审查。
In addition to the identical chassis, the port selection of our test system holds no surprises in store when compared to other g7 models. The buyer gets 2x USB 3.0 and one additional USB 2.0 port. For a fairly large multimedia notebook the port selection is certainly not overwhelming, but nonetheless adequate. Most users will be perfectly happy with aforementioned ports, the display ports (VGA and HDMI), and the usual standard fare of Kensington lock slot and headphone / microphone jacks.
We don't think that the Fast-Ethernet port deserves is name: its maximum speed of 100 MBit/s is simply behind the times. The positioning of the ports could also be better: especially the lack of distance between the USB ports can be problematic if wider thumb drives are used.
除了相同的底盘，我们的测试系统端口选择持有任何疑问，商店，相比其他G7模式。买方获得2个USB3.0和1个额外的USB 2.0端口。一个相当大的多媒体笔记本电脑的端口选择肯定是不能喧宾夺主，但仍然足够。大多数用户会很乐意与上述端口，显示器端口（VGA和HDMI），Kensington锁槽和耳机/麦克风插孔通常的标准票价。
我们不认为快速以太网端口不愧是名，其最大速度为100 Mbit / s是简单地落后于时代。定位的端口也可能是更好的，尤其是缺乏的USB端口之间的距离是问题，如果使用更广泛的拇指驱动器。
Communication
HP didn't go with an offering from well an established manufacturer for the WLAN module - rather, they sourced it from Ralink (a not very well-known company). The entry-level RT5390R only supports single stream (1x1) and therefore limits the transfer rate to 150 MBit/s. The module supports IEEE standard 802.11b/g/n but only offers connections via the 2.4GHz band. An option for 5 GHz as well as a bluetooth module are missing. HP also doesn't offer integrated UMTS or LTE - but considering that this notebook is a desktop replacement, this is certainly not a big deal.
The 0.3 megapixel webcam fails to impress. Because of the low resolution, quality suffers when taking snapshots or recording video clips: images are grainy and lack details. The webcam is just good enough for the occasional video chat and not much more. The microphone, however, is of decent quality and works quite well.
Accessories
HP ships the notebook with a 90 watt power adapter, the battery (which is inserted at the bottom), and a quickstart guide. This should be enough to get a new owner started - but we would have liked to see driver and recovery DVDs included in the box as well.
The HP Recovery Manger allows the user to create their own recovery / system backup set. This requires five DVDs or an adequately sized USB stick. Other included tools, like the Connection Manager, the Security Assistant or the Setup Manager range from useful to completely useless. We really don't appreciate the embedded ad links on the desktop and in the different toolbars of the browser.
Maintenance
After the removal of a single screw, the user can gain access to the inside of the notebook via a useful sliding cover. Unfortunately, the expansion options are limited: the 2.5-inch hard drive carrier and both DIMM slots are already in use; a mSATA connection is not offered. The WLAN module is accessible should a swap become necessary. In order to clean the fan and the heatsink, further disassembly of the unit is required.
Warranty
HP provides a standard one year warranty for their consumer notebooks - only the more expensive EliteBooks come with longer coverage. Fortunately, HP offers a one year extended warranty with pickup and return ("Care Pack"), which can be purchased from various online retailers for about 60 Euro.
通讯
惠普并没有去祭以及WLAN模块的制造商 - 相反，他们采购的，从雷凌（一个不是很知名的公司）。入门级的RT5390R只支持单数据流（1x1）和因此限制了传输速率150兆比特/秒。该模块支持IEEE标准支持802.11b/g/n，但只提供了通过2.4GHz频段的连接。 5GHz的一个选项，以及蓝牙模块丢失。此外，惠普还没有提供集成的UMTS和LTE - 但考虑到这款笔记本电脑是台式机替代品，当然，这是不是一个大问题。
0.3万像素的摄像头，没有留下深刻的印象。由于分辨率低，质量会受到快照或录制短片时，图像的颗粒感，缺乏细节。网络摄像头不够好，只是偶尔视频聊天并没有太大的。然而，麦克风，体面的质量和工作得很好。
饰品
HP会在笔记本的90瓦电源适配器，电池（这是插在底部），快速入门指南。这应该是足以让一个新的主人开始 - 但我们所希望看到的驱动器和恢复DVD包装盒中包含。
HP恢复管理器允许用户创建自己的恢复/系统备份集。这需要5张DVD或足够大的USB记忆棒。其他工具，如连接管理器，安全助手或安装管理范围从完全无用。我们真的不喜欢在桌面上，在不同的浏览器的工具栏嵌入的广告链接。
保养
的单螺杆的去除后，用户可以访问的笔记本的内部通过一个有用的滑动盖。不幸的是，扩展选项是有限的：已经在使用的2.5英寸硬盘驱动器托架和两个DIMM插槽，没有提供一个有mSATA连接。 WLAN模块访问的交换成为必要。为了清洗风扇和散热片，进一步拆卸的单元是必需的。
保
HP提供了一个标准的一年保修期为消费类笔记本电脑 - 只有更昂贵的EliteBook笔记本电脑配有较长的期限。幸运的是，惠普（HP）提供一年的延长保修期，皮卡和返回（“金牌”），它可以从各种在线零售商购买约60欧元。
Input Devices
Since the input devices don't differ much from the AMD models we already reviewed, we will just provide a brief summary in place of a full discussion.
Keyboard
The chiclet keyboard sports a matte black finish and exhibits fairly minimal flex. The keys offer medium resistance when depressed and give precise feedback. Since the surface of the keys (15 x 15 millimeter / 0.59 x 0.59 inches) is textured, even high typing speeds are not a problem. Noise is also well controlled, which further increases the perceived quality.
Touchpad
The Synaptics touchpad (10.5 x 5.3 centimeter / 4.13 x 2.01 inches) is adequately sized and allows moving the cursor across the screen without having to resort to multiple passes. The surface of the touchpad is textured and a bit "draggy", but allows for precise control and gives the user excellent feedback about each movement. We also appreciated the short travel and distinct click-feedback of the individual mouse buttons located directly under the touchpad area.
由于输入设备我们已经回顾AMD机型没有太大的差别，我们只是提供一个简短的总结中充分讨论的。
键盘
的巧克力键盘，体育的磨砂黑色涂层，具有相当小的弯曲。键郁闷的时候，耐介质，并提供精确的反馈。由于表面的键（15×15毫米/0.59×0.59英寸）是质感，甚至高的打字速度是不是一个问题。噪声也被很好地控制，这进一步增加了感知质量。
触摸板
Synaptics触摸板（10.5×5.3厘米/4.13×2.01英寸）是足够大的，可以移动光标在屏幕上，而无需诉诸多遍。在触控板的表面有质感，有点“拖拉的”，但允许进行精确的控制，为用户提供了极好的反馈对每一个动作。我们还赞赏的短行程和独特的个人鼠标按钮位于触控板的面积直属的点击反馈。
Display
One of our main points of criticism when we reviewed the Pavilion g7 before was the very disappointing display. Did HP improve the display for the expensive Intel version? The specs are identical: a 17.3-inch display with a resolution of 1600 x 900 pixels. As a result, the pixel density is fairly low at 106 dpi.
When we measured the display brightness, we could not detect any improvements. On the contrary: We recorded an average brightness of 173 cd/m² - lower than the 181 to 184 cd/m² we measured for the AMD models. Of course this discrepancy could also be due to manufacturing tolerances. Brightness distribution is also a bit worse, although not to the point where it is visible to the eye.
当我们回顾馆G7我们的主要的批评点是非常令人失望的显示。 HP提高了昂贵的Intel版本的显示吗？的规格是相同的：一个17.3英寸的显示屏，分辨率为1600×900像素。作为结果，在106 dpi的像素密度是相当低的。
当我们测量显示器的亮度，我们没有发现任何改善。相反，我们录得的平均亮度为173 cd /m²的 - 低于在181至184坎德拉/平方米，我们测得的AMD机型。当然，这种差异也可能是由于制造公差。亮度分布也差了些，虽然还没有到这样的地步，是肉眼看到。
| |||||||||||||||||||||||||
Brightness Distribution: 88 %
Center on Battery: 174 cd/m²
Contrast: 166:1 (Black: 1.05 cd/m²)58% AdobeRGB 1998 (Argyll 2.2.0 3D)
83.3% sRGB (Argyll 2.2.0 3D)
56% Display P3 (Argyll 2.2.0 3D)
A closer look at the display reveals that HP uses a TN panel from AU Optronics (AUO139E) - the same one also found in the other notebooks of the series. Therefore it comes as no surprise that neither the black point value (1.05 cd/m²) nor the contrast (166:1) differ much from what we measured when we tested the g7-2051sg and the g7-2053sg. The result is a rather unimpressive display - especially noticeable when playing games or watching movies.
The reflective display makes colors look better than they actually are. The sRGB color space is represented for the most part, but the expansive Adobe RGB reference color space is inadequately covered. Of course, the average home user does not work with professional graphics software and won't be adversely affected.
仔细一看发现，在显示HP采用的是TN面板，友达光电（AUO139E） - 在该系列的其他笔记本电脑也发现同一个。因此，毫无疑问，无论是黑点值（1.05 cd /m²的），也不对比度（166:1）从我们所测得的，当我们测试G7-2051sg和G7-2053sg的差别不大。其结果是一个相当不起眼的显示 - 玩游戏或看电影时尤其明显。
反射式显示，使色彩看起来比实际更好。表示的sRGB色彩空间的大部分，但尚未充分包括膨胀的Adobe RGB颜色空间参考。当然，一般的家庭用户不专业的绘图软件，不会受到影响。
As it is always the case with glare-type displays, exposure to bright light decreases the readability of the screen substantially. This is very noticeable during outdoor use - the user usually gets to see his own reflection and not much else. Too bad that the Pavilion g7 doesn't offer a screen brightness of around 250 to 300 cd/m² - it would certainly help out those wanting to take the notebook outside on a bright summer day.
由于它总是与强光型显示器的情况下，暴露在强光下的屏幕大大降低了可读性。这是非常明显的，在户外使用 - 用户通常会看到自己的倒影，并没有多少人。馆G7太糟糕了，不提供屏幕亮度约250至300坎德拉/平方米 - 这肯定会帮助那些希望采取的笔记本电脑，在外面灿烂夏日。
We already talked about the fairly mediocre viewing angle stability of the display when we reviewed the g7-2051sg. Our test sample does as well (or as badly, if you will) as most other notebooks in this price category. Especially when deviating from the vertical, contrast decreases quickly. As long the user only moves sideways a bit and the angle doesn't get to severe, the loss in quality is acceptable.
我们已经谈到相当平庸的可视角度，显示稳定的，当我们回顾的G7-2051sg的。我们的测试样机确实好（或不好，如果你愿意）其他大多数笔记本电脑在这个价格类别。特别是当从垂直方向偏离，对比度迅速下降。只要用户移动侧身位和角度不严重的，在质量上的损失是可以接受的。
If the user does not own an external monitor that supports HDMI, the VGA port is a good alternative. High sharpness and minimal flickering confirm that the analog port is of high quality.
Performance
We already mentioned it: the Pavilion g7 comes in may different flavors and configurations. HP offers both AMD and Intel processors to cover both performance and price aspects.
Our top-of the line test system features the fasted CPU the series offers - an Intel Core i7-3612QM. This quad-core processor is part of Intel's Ivy Bridge lineup and thus features 22 nanometer construction and enhanced energy efficiency. This particular quad-core processor is the only one with a TDP of 35 watts and features a lower frequency of only 2.1 GHz. Depending on load, Turbo Boost 2.0 overclocks the cores up to 3.1 GHz. The CPU also features Hyper-Threading to improve multi-thread performance. For additional information, please take a look at our CPU Database.
Since this is a fast multimedia notebook, the integrated HD Graphics 4000 wouldn't offer enough performance. To that end, HP adds a dedicated middle-class graphics card - a Radeon HD 7670M. To ensure good battery life, the cards get switched dynamically. AMD's "Switchable Graphics" and their answer to Nvidia's Optimus technology is called Enduro.
The g7-2007sg comes with a 750 GB hard drive and 8 GB RAM (two 4 GB modules of DDR3-1600 RAM from Nanya).
我们已经提到：G7国家馆有5种不同口味和配置。 HP都提供了AMD和英特尔处理器的覆盖性能和价格两方面。
我们的顶级的在线测试系统的特点该系列提供最快的CPU - 英特尔酷睿i7-3612QM。四核处理器是英特尔的Ivy Bridge的阵容，因而具有22纳米的建设和提高能源效率。这种特殊的四核处理器的TDP为35瓦，是国内唯一一家拥有一个2.1 GHz的频率较低的。根据负载，睿频加速2.0至3.1 GHz的超频核心。 CPU还支持超线程，以提高多线程性能。有关其他信息，请看看我们的CPU数据库。
由于这是一个快速的多媒体笔记本电脑，集成的高清显卡4000，将无法提供足够的性能。为此，惠普增加了一个专用的中产阶级的图形卡 - Radeon HD7670M的。为了确保良好的电池寿命，网卡的动态切换。 AMD的“可切换显卡”，他们的回答Nvidia的Optimus技术被称为汽车耐力赛。
配备了一个硬盘750 GB和8 GB RAM（2个4 GB DDR3-1600内存模块，来自南亚）的G7-2007sg的。
Processor
We were not overly pleased with the performance of the AMD versions. Many potential buyers are probably going to be interested in the (admittedly much more expensive) laptop featuring the Intel Core i7-3612QM.
| Cinebench R10 - Rendering Single CPUs 64Bit (sort by value) | |
| HP Pavilion g7-2007sg | |
| HP Pavilion g7-2053sg | |
| HP Pavilion g7-2051sg | |
Let's start with the Single-Thread performance. The A10-4600M (2806 points in the Cinebench R10 64 Bit) ranks at the very bottom of the g7 performance list. The A6-4400M features a better Turbo Boost mode and outperforms the 4600M easily (3165 points). Compared to the 5236 points the Core i7 managed to score here, both APUs systems don't stand a chance.
让我们开始的单线程性能。在最底层的G7性能表A10-4600M在CINEBENCH R1064位（2806点）的行列。 A6-4400M提供一个更好的Turbo Boost模式和优于容易4600M（3165点）。的Core i7将比分这里的5236点相比，无论是APU的系统不站在一个机会。
| Cinebench R11.5 - CPU Multi 64Bit (sort by value) | |
| HP Pavilion g7-2007sg | |
| HP Pavilion g7-2053sg | |
| HP Pavilion g7-2051sg | |
The Multi-Threading test Cinebench R11.5 shows an even greater difference in performance. Although the A10 (1.98 points) outscores the (nominally weaker) A6 (1.13 points), the Intel i7-3612QM outperforms both by a fair margin and ends up with 5.66 points. To put that into perspective: even the 45 watt i7-3610QM is only about 10 percent faster. There is no decrease in performance while the notebook is running on battery.
多线程测试Cinebench R11.5更大的性能差异。尽管A10（1.98分）outscores（名义上弱）A6（1.13分），英特尔酷睿i7-3612QM比一个公平的优势，结束了5.66点。为了让大家到的45瓦的酷睿i7-3610QM的观点：即使是只有约10％的速度。有没有降低性能的同时，在笔记本电脑上运行的电池。
Storage Devices
A speedy SSD can't be expected in a notebook retailing for 700 Euro - so we won't hold that against the HP. The 750 GB hard drive is actually an advantage here, as it allows the user to store plenty of photos, movies, and music. The 2.5-inch hard drive is sourced from Toshiba (MK7575GSX), spins at 5400 RPM and has 8 MB cache.
As far as performance is concerned, the Toshiba hard drive can't quite keep up with models spinning at 7200 RPM. The average transfer rate is just above 80 MB/s and random read access time is 16.9 milliseconds (HD Tune). This places the hard drive right in the middle of our benchmark list.
Of course those results pale in comparison with current SSDs. Those willing to give up some storage space in favor of far quicker boot times and application starts, can swap out the hard drive for a SSD (which continue to decrease in price). We'll take more about expansion in our section on "maintenance".
不能预计一个快速的SSD在笔记本零售700欧元 - 所以我们不会对HP。 750 GB的硬盘驱动器实际上是一个优势，因为它允许用户存储大量的照片，电影和音乐。来自东芝（MK7575GSX）2.5英寸硬盘驱动器，转速为5400 RPM，8 MB高速缓存。
就性能而言，东芝的硬盘驱动器没有完全跟上的模型转速为7200 RPM。平均传输速率为略高于80 MB/ S，随机读取时间为16.9毫秒（HD TUNE）。这在我们的基准列表中的硬盘驱动器。
当然，这些结果与目前的SSD相比，显得黯然失色。那些愿意放弃一定的存储空间，支持更快的启动时间和应用程序启动，可以换出的硬盘驱动器SSD（继续减少，价格）。我们要扩大我们的部分“维护”。
System Performance
The PCMark tests from Futuremark are know for reacting strongly to both processor and hard drive speed. Our test system with the Core i7 does exceedingly well here, although high-end notebooks with SSD are able to outperform the g7-2007sg.
The review system with the Intel processor scores 2760 points in PCMark 7 and outscores the models with Trinity APU (it's about 50 to 80 percent faster). Running the older PCMark Vantage, the differences are even more pronounced. The g7-2007sg performs about as well as the Dell Inspiron 17R-SE, which also features a quad-core processor.
Of course it remains to be seen is how noticeable the performance differences are during the daily use of the notebook. Those who mostly surf the Internet, run office type applications, and edit a few photos here and there, are not going to notice a huge advantage to the inexpensive system with the A10-4600M. Power users, who edit HD movies or perform other CPU intensive tasks, are going to reap the benefits of the much faster Core i7-3612QM and the reserves it offers. The system with the Intel chip is going to be a little more future-proof as well.
来自Futuremark的PCMark测试知道反应强烈的处理器和硬盘驱动器的速度。我们的测试系统与酷睿i7不得非常好，在这里，虽然与SSD的高端笔记本电脑能够超越的G7-2007sg的。
审查制度的英特尔处理器得分2760分在PCMark7 outscores的模型与Trinity APU（约50％至80％的速度）。运行PCMark Vantage的，差异更加明显。的G7-2007sg的执行一样，戴尔Inspiron17R-SE，还设有一间四核处理器。
当然，这还有待观察是明显的性能差异是如何在日常使用的笔记本电脑。谁主要上网冲浪，运行办公应用，并编辑了几张照片，在这里和那里，都不会注意到一个巨大的优势，廉价的系统，A10-4600M。电力用户，编辑高清电影，或执行其他CPU密集型任务，要获得更快的酷睿酷睿i7-3612QM和储备提供的好处。采用英特尔芯片的系统将是多

Graphics Card
The AMD Radeon HD 7670M is essentially a newly released version of the Radeon HD 6650M (introduced January 2011). Its processor is still based on the older 40 nanometer process and uses the VLIW5 architecture. The DirectX 11 accelerator has 480 ALUs, separated in 96 blocks, and a frequency of 600 MHz. The memory interface has a 128 bit interface to 1 GB DDR3-VRAM (900 MHz).
The performance of the 7670M makes the card a direct competitor of the GeForce GT 630M, as the results are very close. Running 3DMark 11, the Radeon card scored 1205 points - more than OK for the price bracket of this notebook. Although the less expensive Pavilion g7-2051sg seems to offer better graphics performance due to its Crossfire combination of APU and Radeon GPU (2047 points), it has to be said that it suffers from micro stutters and driver issues (these issues are not reflected in the higher score).
Our test system showed us again that AMD's Enduro technology isn't quite ready for prime time. We miss the ability to select the graphics processor via a handy right click, which is something Nvidia's Optimus offers. There is also no global option to put one or the other graphics processor into service. Since the system rarely selects the dedicated AMD GPU when playing games, the user needs to assign each application manually in the menu of the graphics driver.
Unlike the CPU, running on battery does affect graphics performance, as the GPU throttles down - the score (3DMark 06) is about 40% lower and drops to under 5000 points.
AMD Radeon HD7670M的本质上是一个新发布的版本的Radeon HD 6650M（2011年1月推出）。它的处理器仍是基于较老的40纳米工艺，并使用VLIW5架构。的DirectX 11加速器480的ALU，96块中分离，和一个频率为600 MHz。有128位内存接口接口，1 GB DDR3 VRAM频率（900 MHz）。
的7670M的性能，使卡的GeForce GT 630M的直接竞争对手，因为其结果是非常密切的。 Radeon显卡运行3DMark11，拿下1205点 - 超过确定的这款笔记本的价格支架。虽然较便宜馆G7-2051sg似乎提供了更好的图形性能，由于其（2047点）的APU和Radeon GPU的交火组合，它说，它患有，从微口吃和驱动程序问题（这些问题都不会反映在分数越高）。
我们的测试系统，再次向我们展示了AMD的耐力赛技术是没有完全准备好黄金时间。我们错过的能力是NVIDIA的Optimus提供一个方便的点击鼠标右键，选择“图形处理器通过。也没有将一个或其他图形处理器集成到服务的全局选项。由于系统很少选择专用的AMD GPU玩游戏时，用户需要手动分配给每个应用程序在菜单中的图形驱动程序。
不同的CPU上运行的电池不会影响显卡的性能，GPU节流 - 得分（3DMark 06测试）低40％左右，下降到5000点以下。

Gaming Performance
As far as gaming performance is concerned, the g7-2007sg delivers what we expected from the combination of Core i7-3612QM and Radeon HD 7670M. Using the maximum display resolution of 1600 x 900 pixels while playing any of the current titles, pushes the graphics card quickly to its limits. The user is then forced to either lower the details or to select a lower resolution. The particularly demanding Battlefield 3 requires the lowest quality setting and a resolution of 1024 x 768 to remain playable without any stutters.
Those after the best game-playing experience and additional quality features (AA, AF) need a notebook with a much more powerful graphics processor - at least a GeForce GT 650M or better.
至于游戏性能方面，的G7-2007sg的提供我们所期望的相结合的酷睿i7-3612QM和Radeon HD7670M。使用最大显示分辨率为1600×900像素，在播放任何目前的职称，推动显卡很快到了极限。然后，用户会被迫降低，或选择较低的分辨率。要求特别严格战地3要求的最低质量设置，分辨率为1024×768，仍然没有任何口吃播放。
后最好的游戏体验和额外的质量特性（AA，AF）需要一个更强大的图形处理器的笔记型电脑 - 至少GeForce®（精视™）GT650M或更高。

Noise Level
Even during idle and low ambient temperatures, the fan in the notebook is always on (albeit spinning slowly). The result is a system noise level of 33.1 to 34.2 dB(A) - definitely noticeable in quiet environments. We don't think it's necessary: other notebooks remain passively cooled when the temperature of their processor is between 30 and 40 degrees Celsius (86 to 104 degrees Fahrenheit). The hard drive of the system is barely audible.
During 3D applications, noise level only increases about 3 to 4 dB and reaches 37.6 dB(A). Compared to other 17-inch systems, the g7-2007sg does well here and remains fairly unobtrusive even during longer gaming sessions. The noise level peaked at a surprisingly high 48.2 dB(A) when we ran our stress test - a value that won't be reached during normal use though. Under full load, the fan system emits fairly high frequencies, but when the load decreases, the noise level drops back down within a few seconds.
即使在怠速和低环境温度，风扇在笔记本电脑总是上（虽然慢慢旋转）。其结果是一个系统的噪声水平为33.1至34.2分贝（A） - 在安静的环境肯定明显。我们不认为这是必要的：其他的笔记本电脑仍然被动冷却时，他们的处理器的温度是摄氏30至40度之间（86至104华氏度）。硬盘驱动器的系统是几乎听不见。
在3D应用程序，噪音水平仅增加约3至4分贝，达到37.6分贝（A）。相比其他17英寸系统，G7-2007sg的做得很好，仍然是相当不显眼，甚至在更长的游戏时间。噪音水平达到顶峰在高得惊人48.2分贝的（A）当我们运行我们的压力测试 - 一个值，将在正常使用过程中，虽然不能达到。在满载条件下，风扇的系统发射的频率相当高，但是当负载减小时，在几秒钟内，噪声电平会下降。

Temperature
While performing normal office duties, the temperature of the test system only increases marginally and is barely above ambient. Without any significant load, the top and the bottom of the laptop only reach about 30 degrees Celsius (86 degrees Fahrenheit). The notebook can therefore be used on the lap without issues.
Things change rapidly when we simulate a high load using Prime95 and FurMark. We measured between 50 to 60 degrees Celsius (122 to 140 degrees Fahrenheit) in some areas - for example around the system fan vent and the battery. What we noted in our section on Noise Level holds true here, too - those extreme values are usually the result of synthetic benchmark testing and don't reflect every day use.
The reason why HP decided to use the more energy efficient Core i7-3612QM and not (a more powerful) 45 watt processor becomes evident when we take a closer look: during the stress test, the processor frequency decreases first to 2.1 GHz and even throttles down to 1.2 GHz after longer run times. The CPU core temperature hovers around 85 degrees Celsius (185 degrees Fahrenheit). We were unable to obtain a result for the Radeon HD 7670M, although we didn't encounter any throttling. It has to be said that throttling really is a non-issue, as a 3DMark 11 test conducted directly after the stress test didn't show a decrease in performance at all.
在执行正常的办公室工作，只会增加测试系统的温度轻微和是勉强高于环境。没有任何显着的负载时，顶部和底部的笔记本电脑只能达到约摄氏30度（华氏86度）。没有问题的，因此可用于笔记本电脑放在膝上。
事情变化很快，当我们模拟了高负荷使用Prime95和FurMark进行。我们测量摄氏50至60度（华氏122至140度），在某些领域 - 例如周围的系统的风扇通风口和电池之间。我们注意到在我们的部分噪音级别拥有真正的在这里，太 - 这些极端值通常是合成基准测试的结果，并不能反映每天使用。
HP之所以决定使用更节能的酷睿i7-3612QM，而不是（更强大）45瓦处理器，成为显而易见的，当我们仔细看看：在压力测试中，处理器的频率降低到2.1千兆赫，甚至节流后下降至1.2 GHz较长的运行时间。 CPU核心温度降到摄氏85度左右（华氏185度）。我们无法获得的结果为Radeon HD7670M，虽然我们没有遇到任何限制。它说，节流真的是一个不是问题的问题，作为一个3DMark 11测试后直接进行压力测试并没有显示出在所有的性能下降。
(-) The maximum temperature on the upper side is 55.2 °C / 131 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(-) The bottom heats up to a maximum of 60 °C / 140 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 28.2 °C / 83 F, compared to the device average of 31.3 °C / 88 F.
(-) The palmrests and touchpad can get very hot to the touch with a maximum of 40.3 °C / 104.5 F.
(-) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (-11.5 °C / -20.7 F).
Speakers
Since the Pavilion g7-2007sg shares the same chassis with the already reviewed AMD systems, it comes as no surprise that the sound system is identical. The stereo speakers from Altec Lansing are clear and sufficiently loud. We don't really like the overbearing highs and the more or less completely lacking bass. The user can adjust the settings using the equalizer and improve the sound a bit. In cases where the laptop remains stationary, we recommend hooking up external speakers using the (3.5 millimeter) audio jack or the HDMI port.
由于馆的G7-2007sg股份的相同的底盘已经评论的AMD系统，这是毫不奇怪的音响系统是相同的。从奥特蓝星立体声扬声器清晰，响亮程度足以。我们真的不喜欢咄咄逼人的高点和或多或少的完全缺乏低音。用户可以调整使用均衡器的设置，和改善的声音有点。在笔记本电脑保持固定的情况下，我们建议使用（3.5毫米）音频插孔或HDMI端口连接外部扬声器。
Power Consumption
Although the g7-2007sg is quite powerful, the notebook is very frugal while idling and only consumes between 10.4 and 12.3 watts - a result almost identical to the model with the AMDs Trinity-APU A10-4600M. Even compared to other large multimedia notebooks like the Dell Inspiron 17R-SE , the laptop does well here.
The 3DMark 06 result (which we will use here in place of 3D games) is quite surprising, as it comes in at a really low 44 watts. Only when we subject the processor and the graphics card to maximum load, we start pushing the power adapter (90 watts) to its limit - we recorded up to 86.6 watts. The aforementioned throttling keeps things under control and reduces power consumption to between 60 and 70 watts intermittently.
尽管G7-2007sg是相当强大的，笔记本电脑是非常节俭空转时仅消耗10.4瓦和12.3瓦之间 - 模型与AMD的三位一体APU A10-4600M结果几乎相同。即使与其他大型多媒体笔记本电脑，戴尔Inspiron17R-SE等，笔记本电脑以及在这里。
3DMark 06测试结果（在这里，我们将使用地方的3D游戏）是相当惊人的，因为它有一个真正的低44瓦。只有当我们受到的处理器和显卡的最大负载，我们开始推到了极限，电源适配器（90瓦） - 我们录得高达86.6瓦。上述限制下保持控制并降低功耗60瓦和70瓦之间的间歇。

Battery Life
Since the power consumption is very close to results the AMD models posted, we expected the Intel version of the Pavilion g7 to score almost the same.
Think again: Instead of lasting 8 hours, the notebook shuts down after 5 hours and 38 minutes in our Battery Eater Readers Test (WLAN and GPU turned off, power saver profile, display brightness turned all the way down). We can't really explain the result, but unfortunately we don't have access to the AMD test systems to figure why the results are so different.
While surfing via WLAN (GPU turned off, power saver profile, display brightness of 150 cd/m²), the notebook reached a decent 3 hours and 53 minutes. This test (a script that opens different websites and HD videos every 40 seconds) is more realistic than the scenario described above.
Any power saving measures don't really come into play when subjecting the notebook to heavy loads during the Battery Eater Classic Test (WLAN and GPU on, high performance profile, maximum brightness) - so the expected run time is short. The Pavilion lasted about 46 minutes before it shut down. Recharging takes about one and a half hours.
由于功耗的AMD机型发布的结果非常接近，我们预计G7得分几乎相同的Intel版本的展馆。
再想想：持续8小时，而是在笔记本电脑关闭后5小时38分钟的电池食读者测试（无线区域网路（WLAN）和GPU关闭显示器的亮度，省电的个人主页上，把所有的）。我们不能真正解释的结果，但不幸的是，我们没有获得AMD测试系统计算的结果为何是如此的不同。
上网时，通过WLAN（GPU关闭，省电的个人主页上，显示器的亮度为150坎德拉/平方米），笔记本电脑达到一个体面的3小时53分钟。这个测试（脚本，打开不同的网站，高清视频，每40秒）比上面描述的场景是比较现实的。
任何节能措施并没有真正开始发挥作用时的笔记本在电池食经典测试（WLAN和GPU，高性能的个人主页上，最大亮度） - 预期的运行时间短的重物。馆历时约46分钟，然后才关闭。充电时间约一个半小时。
Verdict
The price difference between the HP Pavilion g7-2007sg and the (previously reviewed) g7-2051sg with AMD A10-4600M is about 150 Euro - a pretty significant jump. Is this money well spent?
In addition to the additional RAM, the price increase can be attributed to the Core i7-3612QM. On the plus side, the Intel CPU does offer two to three times the performance of the Trinity APU - especially noticeable during photo editing or working with video software. Processor intensive games (for example simulation or strategy games) also benefit from the additional performance. Of course, it's mostly the graphic card which restricts frame rates and thus gaming performance. We wouldn't recommend this notebook for hardcore gaming anyways - although those wanting to play the occasional game or multimedia fans should be quite pleased with it.
Our main points of criticism are elsewhere: the glossy and moderately sturdy chassis, the very slow Fast-Ethernet port, and a fan system that's always on - it would be great if HP could make some improvements here. What we really would wish for is a better (at least brighter) display.
Since the price-performance ratio is very good, we are inclined to overlook some of the weaknesses. Overall we can recommend the system - with some caveats. Competing (and similarly equipped) models, like the Dell Inspiron 17R-SE or Lenovo G780 retail for 50 to 100 Euro more. On the other hand, there's competition from within: the less expensive HP Pavilion g7-2051sg is probably sufficient for many users.
与AMD A10-4600M的HP Pavilion G7-2007sg和以前审查G7-2051sg之间的价格差异大约是150欧元 - 一个非常显着的跳跃。这钱花得值吗？
除了额外的RAM，价格上涨可以归因于酷睿i7-3612QM。从有利的一面，英特尔CPU提供的两到三倍的三位一体的APU - 特别引人注目的照片与视频软件编辑或工作过程中的表现。处理器密集型游戏（例如模拟战略游戏）也受益于额外的性能。当然，这是主要的图形卡，限制帧速率和游戏性能。我们不推荐这款笔记本的为铁杆游戏反正 - 虽然那些想要偶尔玩游戏或多媒体的球迷应该是很高兴的。
我们的主要的批评点是在其他地方的光泽和适度坚固的底盘，很慢的快速以太网端口，和一个风扇系统，总是在 - 这将是巨大的，如果惠普可以在这里做一些改进。我们真正希望的是一个更好的（至少较亮）显示。
由于价格性能比是非常好的，我们倾向于忽视的一些弱点。整体而言，我们建议系统 - 一些需要注意的地方。竞争模型（同样配备），像戴尔Inspiron17R-SE或联想G780零售价为50至100欧元。另一方面，有竞争从较便宜的惠普Pavilion G7-2051sg是对于许多用户可能就足够了。
