戴尔 Latitude E5430 笔记本

Embracing the mantra of preserving what works, Dell has left well enough alone in nearly every aspect of the E5430’s construction. You’ll find a virtually identical design to that of its elder (the E5420), and considering our overwhelmingly positive feedback for that aspect of it, there isn’t much room for concern with what largely qualifies as a component-level update.

The first thing to note is that the casing, while again, not as heavy-duty or high-quality as the front-running E6XXX models, is still predominantly solid. The first clue the E5430 offers in this regard is its considerable weight. At 2.51 kg, this is a far cry from a featherweight ultraportable. Nevertheless, in conjunction with its reasonably-designed form factor, it is hardly restrictive in its size. It feels comfortable on the lap and is easier to use than many smaller notebooks in such a position thanks to an adequately-sized, flat palm rest—and this is in spite of the weight and size of the extended battery we received to boot. Very little flex is detectable anywhere apart from just above the optical drive, which is a typical and forgivable weakness of nearly every notebook. While our E5530 review unit was afflicted by some notable gaps between casing components, we are pleased to report that no such problems apply to the E5430 we received.

The display lid is well-supported thanks to strong, metal hinges which are puzzlingly concealed by a deceptive plastic sheathing. As such, it’s hardly affected by any minor bumps and bounces. The lid itself is backed by brushed aluminum, featuring a chrome Dell logo centered amongst the understated uniformity. Apart from looking quite nice, it’s also very protective, preventing all but the slightest amount of distortion on the LCD panel even under reasonable stress, and also doubling-down with commendable scratch resistance. While fingerprints aren’t a major problem, they do require a bit of effort to remove once present.

Elsewhere, the function-over-form philosophy persists. The various ports are rock-solid and firmly attached, and the zinc-plated hinge leaves little room for concern in spite of its singularity. The muted coloring and matte finishes throughout exude a subtle, down-to-earth, and thoroughly professional feel.

We mentioned in our E5530 review the relative ease of accessing and replacing a broken LCD panel in the event of an accident. That benefit extends to the E5430, as well as the usual attention to all-round painless service and maintenance. A single panel on the bottom of the notebook—secured by just two screws—conceals all of the common upgradeable/replaceable components, including the hard drive, RAM, WLAN card, WWAN card (if included), heatsink/CPU, and one empty ½ mini PCIe expansion slot. The slots are conveniently marked and most every screw used in the construction of the notebook is identical and thus interchangeable, making disassembly/reassembly a breeze.

拥抱保护的口头禅是什么在起作用，戴尔已经离开不够好孤单E5430的建设中的几乎每一个方面。其前辈（E5420），你会发现一个几乎相同的设计，我们非常积极的反馈这方面的考虑，没有太多的空间，关注什么资格主要是因为组件的更新。

首先要注意的是，外壳，同时，再次，重型或高品质的前E6XXX模型，是静静的主要固体。第一个线索，在这方面，E5430报价是相当大的比重。 2.51公斤，这是一个轻量级的超便携相距甚远。然而，在结合其合理的设计的外形，它是在它的大小几乎没有限制性。上一圈，感觉舒适和更容易使用，比许多更小的笔记本电脑在这样的位置要归功于充足的大小，平面掌托，这是在我们接收到启动延长电池的重量和体积，尽管。非常小的柔性电路板检测到任何地方，除了以上的光盘驱动器，这是一个典型的和原谅的弱点，几乎所有的笔记本电脑。虽然我们的E5530审查单位被折磨了一些显着的套管组件之间的差距，我们很高兴地报告说，没有这样的问题适用于我们收到的E5430。

的显示屏盖是很好的支持的感谢，强烈的，令人费解的金属铰链，它们掩盖了一个塑料护套欺骗性。因此，它几乎不受任何轻微的颠簸和跳动。盖本身的背后是拉丝铝，镀铬的戴尔标志中心之间的低调均匀。除了看起来相当不错，也非常注意保护，防止所有，但丝毫的失真量的LCD面板，即使在合理的压力，从而增加一倍，值得称道的抗划伤性。而指纹是不是一个主要的问题，他们确实需要一点努力消除曾存在。

在其他地方，功能重于形式的哲学仍然存在。坚如磐石的各个港口，安装牢固，镀锌铰链留下很少的空间，尽管它的奇异关注。静音着色，磨砂完成整个散发出一种微妙的，下到地上的，和十分专业的感觉。

我们在我们的E5530审查相对容易的访问和更换损坏的液晶面板在发生事故时提到。这种好处延伸到E5430，以及全方位的服务和维护无痛平时注意。在笔记本电脑底部的抵押，只需两个螺丝，隐藏的共同所有的升级/更换的部件，包括硬盘驱动器，内存，无线网卡，WWAN卡（如果有），散热片/ CPU，和一个空的单面板半高迷你PCIe扩充槽。这些插槽可以方便地标记，每一个螺丝建设的笔记本电脑中使用的是相同的，可互​​换的的马尔萨斯，使拆卸/重新组装一件轻而易举的事。

Keyboard

Two different keyboards are available for the Latitude E5430: a standard (still excellent) model, and a nicer backlit model. Our review unit included the latter, and as usual, we were impressed by its performance. The backlit keyboard is not only convenient for low-light usage, but it actually features an overall better feel than the standard keyboard. In comparison, it has a softer touch with a slightly rubbery finish, while the standard keyboard feels a bit cheaper, is a little louder, and requires a bit of a heavier stroke to invoke a keypress. While both keyboards are very good, given the option, we would always recommend choosing the backlit keyboard for these reasons alone.

The backlit keyboard included with our review model is, in our opinion, one of the best keyboards currently available on any notebook. It features large-surfaced keys with a comfortable sense of travel and feedback that require only a reasonable amount of effort to depress. This renders typing a pleasure, so much so that I actually chose to write a significant portion of this review on the notebook.

Touchpad

Also impressive, though to a somewhat lesser extent, is the touchpad. Manufactured by Alps Electric, it’s sufficiently large and features a smooth, frictionless surface that resists sticking. The two buttons below it are detectably hard plastic, but they’re nevertheless fairly sturdy and simultaneously quiet (once again, the premium-grade rubberized buttons are only available on the 6XXX E-series Latitudes). The included Dell Touchpad software provides additional customization over gestures, scrolling settings, sensitivity, and palm check functionality.

If you prefer a pointing stick, keep in mind that this is one other feature you’ll only find on the backlit keyboard—the standard keyboard is completely without one. The optional pointing stick includes its own three buttons below it (a left, right, and middle button) and feels comfortable to use.

键盘

两个不同的键盘是为Latitude E5430一个标准依然出色的模型，和一个更好的背光模式。我们的审查单位包括后者，和往常一样，我们留下了深刻的印象，它的性能。背光键盘不仅方便在光线较弱的使用，但它实际上具有更好的整体感觉比标准键盘。比较，它具有柔软触感与一个稍微橡胶的完成，而标准键盘感觉便宜一点，是一个大声一点，需要一点点较重的行程调用按键。虽然这两个键盘都非常好，可以选择，我们总是会建议选择背光键盘，这些原因。

背光键盘，包括我们的审查模式是，在我们看来，目前可在任意笔记本上最好的键盘之一。它具有表面大键与舒适感的旅行和反馈，只需要一个合理的努力压低。这使得键入的快感，让这么多，我选择了写这篇评论在笔记本电脑上的一个重要部分。

触摸板

如此令人印象深刻，但在较小的程度上有些什么，是触摸板。阿尔卑斯电气制造，这是足够大的，具有光滑，摩擦表面抗粘。下方的两个按钮可检测的硬质塑料，但他们坚固，同时不过还算安静（再次，溢价级的橡胶按钮只适用于E-系列的Latitude6XXX）。包括戴尔的触摸板软件提供了额外的自定义手势，滚动设置，灵敏度，和棕榈检查功能。

如果你喜欢指点杆，记住，这是另外一个功能，您将只在背光键盘的标准键盘是完全没有。可选的的指点杆包括自己的下面三个按钮（左，右和中间的按钮），使用感觉舒适。

While other changes have taken place, the big story with Dell’s 2012 Latitude refresh is the inclusion of Ivy Bridge CPU options. Less pricey Sandy Bridge models are still available, and neither choice will result in a slow PC by any judgment. It’s worth noting that Dell also lists Intel Celeron Bxxx CPUs as an option, but as of this writing such a configuration isn’t selectable. Beyond that, the choices range from a Core i3-2328M Sandy Bridge CPU all the way to a 2.9 GHz Core i7-3520M, the latter of which is currently the fastest dual-core Ivy Bridge CPU around. Our review model features a 2.8 GHz Core i5-3360M, which is only slightly slower than the top-end Core i7-3520M.

This CPU supports Turbo Boost and HyperThreading, launching—when needed—into clock speeds as high as 3500 MHz (single-core) and 3300 MHz (multi-core). Sporting a 35 W TDP, it sips power just as efficiently as its predecessors while simultaneously turning in improved performance with its 22 nm architecture and 3D transistors.

The Core i5-3360M also features an integrated Intel HD Graphics 4000 GPU. It’s no secret that we’ve been impressed with this GPU’s performance; it’s not only more powerful than its predecessor (Intel HD Graphics 3000) by around 30%—40% (depending on the application, of course), but it can even handle just about any business task with ease, manage to play many games at respectable (albeit generally lower-end) settings, and still succeeds in consuming less power than nearly any other comparable GPU. The impressive power efficiency is largely a result of its ability to heavily scale its clock rate using Turbo Boost from the base frequency of 350 MHz all the way to 1200 MHz when warranted. For more detail on the GPU’s performance, don’t miss our dedicated Intel HD Graphics 4000 benchmarks page.

Two Nanya 2 GB DDR3-1600 RAM modules (4 GB total) came installed in our review unit, which is more than enough for most users. But with the extremely low prices of DDR3 RAM and the considerable ease of upgrading components in the Latitude E5430, it’s easy to justify a higher amount. Fortunately, up to 16 GB of RAM is supported (8 GB per slot), so there should be no trouble reaching a sufficient number.

As part of our usual extensive testing, we ran DPC Latency Checker on our E5430 test unit and encountered substantial latency (>4000 µs) roughly every 30 seconds. This latency was resolved completely, however, once the Intel 6205 WLAN adapter was disabled. Interestingly, on our E5530 review unit, we experienced comparable latency issues, but in that instance it was disabling of the Bluetooth module which rectified the problem. Nevertheless, after repeated tests, it is indeed the WLAN adapter which is to blame on the E5430.

而其他的都发生了变化，大的故事与戴尔的Latitude 2012刷新列入Ivy Bridge的CPU选项。减昂贵的Sandy Bridge模式仍然可用，并，既不选择将导致一个缓慢的PC的任何判决。值得注意的是，戴尔列出英特尔的赛扬BXXX CPU作为一种选择，但这样的配置写这篇文章是不可选除此之外，酷睿i3-2328米的Sandy Bridge CPU的选择范围从所有的方式到2.9 GHz的Core睿i7-3520米，其中后者是目前速度最快的双核心Ivy Bridge的CPU周围。我们的审查模式，采用了2.8 GHz的Core i5-3360米的，这仅是略慢于最高端的酷睿i7-3520米。

该CPU支持Turbo Boost技术和超线程技术，发射时需要将时钟速度高频率为3500 MHz（单核）和3300兆赫（多核）。运动35W的TDP，喝了几口电源作为它的前辈一样高效的22纳米架构和3D晶体管的同时，转向性能的提高。

因此，i5-3360米的核心采用了集成的英特尔HD Graphics 4000 GPU。它是没有秘密，我们已经被留下深刻的印象与此GPU的性能，它不仅更强大的比其前身（英特尔HD Graphics 3000）约30％-40％（取决于上的应用，当然），但它甚至可以处理几乎任何业务游刃有余，玩很多游戏在尊敬的（尽管是低端的反弹产生），仍然成功在消耗更少的功率比几乎任何其他类似的GPU。令人印象深刻的功率效率在很大程度上是由于它的扩展能力大量使用涡轮增压的基础频率为350 MHz一路到1200 MHz的时钟速率时，保证。对于更详细的GPU（图形处理器）的性能，千万不要错过我们的专用的英特尔HD 4000基准测试页。

两个南亚2 GB DDR3-1600内存模块（共4 GB）来安装在我们的审查单位，这对于大多数用户来说足够多。但以极低的价格在Latitude E5430的升级组件的DDR3内存和相当容易，可以很容易地证明了更高的金额。幸运的是，高达16 GB的RAM，支持8 GB（每插槽），所以应该没有问题，达到足够的数量。

作为我们平常了广泛的测试的一部分，我们跑了DPC的时延检查我们的E5430的测试单元，并遇到了重大的延迟（> 4000美国）大约每隔30秒。潜伏期彻底解决，但是，一旦英特尔6205无线适配器禁用。有趣的是，我们的E5530审查单位，我们经历了比较延迟问题，但在该实例中，它被禁用蓝牙模块，纠正问题。然而，经过反复试验，它的确是责怪的E5430无线适配器。

Storage Devices

The Latitude E5430 can be outfitted with either a 320 GB (encrypted or non-encrypted) or 500 GB 7200 RPM hard drive, or for a little higher cost, a 128 GB Solid State Drive (SSD). Our review unit came equipped with a Seagate Momentus Thin ST320LT007-9ZV142 7200 RPM 320 GB drive. Like the drive we received in our E5530 review model, this is a smaller, single-platter 7 mm-height hard drive that normally is meant for situations where drive size is a prohibitive design factor (such as in many ultraportables). The E5430 actually features a fully-sized 9.5 mm-height drive bay, so any traditional SATA laptop drive will also fit.

The Seagate Momentus Thin posted excellent speeds that rival some of the fastest laptop hard drives we’ve benchmarked. Its Transfer Rate Average of 97.3 MB/s puts it directly in competition with Hitachi’s Travelstar Z7K500, which is a fine drive to have in company. Meanwhile, the Access Time of 17.3 ms isn’t anything remarkable, but it’s not overly offensive either. The gist is that if you’re fortunate enough to receive the same drive, you can enjoy the comfort of knowing that you are working with one of the quickest notebook hard drives of its size.

Also featured in all configurations of the Latitude E5430 is a Dell Fast Response Free Fall Sensor, which functions independently of the installed storage device (it’s a board-level feature) and helps protect the drive against sudden changes in the position of the notebook.

 存储设备

可以配备320 GB（加密或非加密的）或500 GB 7200 RPM硬盘驱动器，或高一点的成本，一个128GB的固态驱动器（SSD）的Latitude E5430。我们的审查单位来配备了一块希捷的Momentus薄ST320LT0079ZV1427200 RPM320 GB的驱动器。驱动器，我们收到了我们的审查模式E5530一样，这是一个较小的，单碟7毫米高的硬盘驱动器的情况下，通常是驱动器的大小是一个令人望而却步的因素设计（在许多超便携测试）。 E5430拥有一个全尺寸的9.5毫米高的驱动器托架，所以也适合任何传统的SATA笔记本硬盘。

希捷Momentus薄发布了出色的速度可以媲美一些速度最快的笔记本电脑的硬盘驱动器，我们已经为基准。它的平均传输速率为97.3 MB/ s的把它与日立的Travelstar Z7K500，这是一个很好的驱动器在该公司直接竞争。同时，访问时间为17.3 ms的是没有任何显着，但它不是过于进攻。其要旨是，如果你有幸收到相同的驱动器，你可以知道你是最快的笔记本电脑的硬盘驱动器，其规模与舒适的享受。

因此，在所有配置的纬度E5430是戴尔一个有特色的快速响应免费秋季传感器，哪一个功能独立的安装存储设备，它是一个板级功能之一，并有助于保护驱动器针对笔记本电脑的位置的突然变化。

System Noise

Again following in the footsteps of its larger brother, the E5430 can get quite loud under load. But also like its sibling, it’s rare that it reaches this point. Under most circumstances, when idle, the machine is nearly silent with an average noise level of just 32 dB. It’s when the system is heavily stressed that things become a little more questionable, with maximum noise under load reaching as high as 49.4 dB. Fortunately, the median load volume is still just 34.5 dB, indicating how infrequently this actually becomes a problem. Furthermore, it’s worth mentioning that if the noise does happen to become too annoying to tolerate, it’s always possible to select one of the specially-tailored power plans Dell has included—such as Quiet (Reduced Fan Levels)—to force the machine to operate at a lower volume at the expense of some performance.

系统噪声

后再次在大哥哥的脚步，的E5430可以得到相当大的负载下。但也像它的兄弟姐妹，这是罕见的，做到了这一点。在大多数情况下，空闲的时候，机器几乎是无声的，平均只有32分贝的噪音水平。这是当系统的压力很大，事情变得有点可疑，最大负载达到高49.4分贝的噪音下。幸运的是，负荷量中位数仍是只是34.5分贝。这其中常常成为一个问题此外，值得一提的，如果噪音不会发生变得太烦人容忍，它总是可能的，以选择1了专门的量身定制的电源计划，戴尔已经包括的检查一样安静（减少风扇的水平），以迫使机器运行以较低的音量在牺牲一些性能。

Throttling

Part of every review we assemble includes a system stress test to check for throttling when the CPU and GPU are stressed both simultaneously and independently of each other. Such testing simulates the use of the system under maximal load, a situation which few users will ever experience but which still provides useful insight into the stability of the notebook. We perform this testing with the help of Prime95 and Furmark.

During our throttle testing of the E5430, when either CPU or GPU were stressed independently, temperatures remained reasonable and no throttling (and very little wavering of the Turbo Boost frequencies) occurred. The situation was somewhat different when both were stressed together: the CPU clock rates still generally hovered around the multi-core maximum of 3300 MHz, but GPU wavered a bit more noticeably around the 1100—1150 MHz mark. Nevertheless, this is still very close to the absolute maximum Turbo Boost frequency of 1200 MHz, and this is much better than the E5530 fared under these same conditions. To get an idea of how much better the E5430 handled the challenge than the E5530, take a look at our corresponding screenshots for Full system stress on both articles. Compare the red graph for the GPU Core Clock and you’ll witness the faltering Turbo Boost operations in action.

Notebooks which do not exhibit hardship maintaining maximal Turbo Boost frequencies for lengthy periods of time will be less likely to exhibit performance hiccups during heavy gaming and other stressful situations. To be certain that the E5430 was not adversely affected by long periods of heavy use, we performed another benchmark run of 3DMark 06 directly after our full system stress test of over an hour. The score of 5658 confirms that very little (if any) residual performance detriment results from heavy stress on the E5430.

节流

评论组装系统，包括压力测试，以检查是否有限制时，CPU和GPU都强调，同时彼此独立。搜索测试模拟在最大负载下系统的使用，很少有用户会遇到这种情况，但成静音笔记本电脑的稳定性提供了有益的启示。执行此测试的帮助下，Prime95和Furmark的。

Speakers

As is the case with nearly every business notebook, the Latitude E5430’s dual speakers provide only the bare minimum audio performance. While higher frequencies are clear, there is very little low frequency response at all, at the sound as a whole is consequently somewhat flat. Overall, though, it’s not terribly bad for a business notebook. The sound is notably improved when the notebook is resting on a hard surface, a result of the down-firing speaker design that leverages the acoustics of the surface to project the sound.

音箱

的情况一样，几乎所有的商用笔记本电脑的Latitude E5430的双扬声器很抱歉只有最小的音频性能。而更高的频率是明确的，有非常小的低频率响应，因此有些作为一个整体的声音是平坦的。不过，总的来说，这是不是非常坏的一款商务笔记本。显着提高笔记本电脑放置在坚硬表面上，向下发射扬声器的设计，充分利用了声学的表面投射的声音的声音。

Early last year, our review of the Dell Latitude E5420 expressed our appreciation of its sturdy construction, first-rate keyboard and touchpad, great battery life, and practical design—elements which have become synonymous with the Latitude brand. Still, we were left dreaming of a higher-quality screen, less noise under load, and USB 3.0. Does the E5430 answer our call?

Suffice it to say, the Latitude E5430 is yet another step toward affordable perfection in the business market. It represents an intelligent balance between luxury and economics, focusing on the areas which matter most and skimming over some of the more robust details championed by the upper-echelon Latitude E6XXX series. It improves upon its predecessor by adding USB 3.0 (2 ports) and extending the battery life while simultaneously improving performance—even in the graphics department, which continues to impress with the help of the Ivy Bridge-based Intel HD Graphics 4000.

Regardless, there are a few areas where the E5430 still falls short. The first is display quality; while our upgraded 1600x900 HD+ panel is certainly adequately bright for even outdoor use, the contrast ratio and color spectrum leave much to be desired. It’s also still quite a loud machine, reaching disturbing decibel levels under moderate levels of stress (though this behavior can be adjusted at the expense of some performance using Dell’s built-in power plans). And finally, the weight—while partially a factor of the heavier-than-usual build quality—is more prohibitive than that of many competing 14” notebooks.

Ultimately, though, provided one can overlook these relatively minor shortcomings and the lack of the premium finish bestowed upon the E6XXX series, the E5430 is an obvious choice. Competitors such as the Lenovo ThinkPad T430 and L430 will probably give it a run for its money, but it’s hard to go wrong with the E5430 in any case.

 早在去年，我们的审查，戴尔Latitude E5420表达我们的升值，其坚固的建筑，一流的键盘和触摸板，很长的电池寿命，以及实际的设计元素，这已成为代名词的品牌纬度。不过，我们的高品质的画面，噪音更小负载下，USB 3.0的梦想。 E5430回答我们的电话吗？

我只想说的Latitude E5430是又一步步走向商业市场的价格实惠的完美。它代表。智能豪华和经济之间的平衡，重点领域最重要的，一掠而过一些更强大的细节倡导的上层梯队纬度的E6XXX系列它提高了其前身后，加入USB 3.0（2个端口），并延长电池的使用寿命，同时提高性能，即使是在图形部门，继续留下深刻的印象的帮助下，基于Ivy Bridge的英特尔HD Graphics第4000

无论如何，有几个地方E5430悄悄地落在短。首先是显示质量，而我们的升级1600X900 HD+面板肯定是足够明亮，即使在户外使用，对比度和色彩频谱留下许多有待改进。它也很安静，一个响亮的机器，达到令人不安的分贝水平，中等水平的压力下（虽然这种行为可以牺牲一些性能，使用戴尔的内置电源计划）的调整。最后，重量，同时部分比平常重建设质量的一个因素，更多的是比许多相互竞争的14“笔记本电脑望而却步。

不过说到底，提供了一个可以忽略的溢价完成E6XXX系列赋予这些相对较小的缺点和缺乏，E5430是一个显而易见的选择。联想ThinkPad T430和L430的竞争对手寻求将可能给它一个运行的钱，但出问题的E5430，在任何情况下，这是很难的。
