蓝天 P370EM Barebones 笔记本测评

The Clevo P370EM barebone, weighing 4.3 kg (9.48 pounds) with two graphics cards, seems to be a mixture of the beloved P170EM barebone (single GPU, ~3.9 kg, 8.6 pounds) and the massive X7200 barebone (dual GPU, ~6.0 kg, 13.22 pounds).

With a footprint of 419 x 293 mm (16.5 x 11.5 inches) the XMG P722 is somewhat bigger than its brother the XMG P702 (412 x 276 mm, 16.22 x 10.86 inches), but the height of the notebook is about 55 mm (2.16 inches). For comparison: the old XMG U700 was 419 x 286 x 73 mm (16.5 x 11.25 x 2.87 inches).

The consumer is greeted by a successful mix of dark gray plastic surfaces and black aluminum (keyboard area). The palm rests and the lid have a rubber finish, which not every user will enjoy. The reason: The rubber coating is quite sensitive to wet or greasy fingers. After just a few hours, our test unit was covered in various stains. But the feel of it was quite comfortable.

To a large extent there are no reflecting elements, with the touchpad being one of the few exceptions (a matte display frame is not always expected from Clevo). Although the design has become a bit more modern, the overall look of the 17-inch notebook is relatively plain. Another plus is the great workmanship: Even after a close inspection, one finds at most only minor discrepancies. The material quality is also very good, although you should not expect any new records. The Alienware M18x R2 is still qualitatively in a higher league.

In terms of stability, the notebook leaves an overall positive impression. Even under high pressure, the chassis feels pretty stiff and only gives in minimally. The rigidity of the display lid on the other hand is average. Thanks to the high weight, the base unit does not move when opening the lid.

蓝天P370EM的重达4.3公斤（9.48磅）用两块显卡，准系统，似乎是心爱的P170EM准系统（单GPU〜3.9千克，8.6磅）和大量的X7200准系统（双GPU〜6.0公斤的混合物，13.22磅）。

XMG P722的外形尺寸为419 x 293毫米（16.5×11.5英寸）的是稍微大于它的兄弟XMG P702（412 X276毫米，16.22所述10.86英寸的次），但笔记本电脑的高度大约是55毫米（2.16英寸）。比较：老XMG U700为419所述286 x 73毫米（16.5×11.25所述2.87英寸）。

消费者映入眼帘的是一个成功的组合，暗灰色的塑料表面和黑色铝（键盘区域）。掌托和盖有一个橡胶面漆，并不是每个用户都将享受。原因是：橡胶涂层，是相当敏感，潮湿或油腻的手指。经过短短几个小时，我们的测试样机上，包括在各种污渍。但它的感觉还是挺舒服的。

在很大程度上，有没有反射的元素，用触摸板是为数不多的例外之一（磨砂显示框不会总是期望从蓝天）。虽然设计已经成为一个更现代的，17英寸的笔记本的整体外观是相对简单的。另一个好处是伟大的做工：即使经过仔细检查，发现最多只有轻微的差异。材料的质量也非常好，虽然你不应该指望任何新的记录。 Alienware的M18x R2仍然是在一个更高的联赛定性。

在稳定性方面，的笔记本留下一个整体的积极的印象。即使在高压力，底盘感觉很僵硬，只给在最低限度。上显示盖的刚性，另一方面是平均的。由于权重高，基本单元不动时，打开盖子。

Processor

The mobile high-end class has been dominated by Intel's Core i7 processors for quite some time. The current Ivy Bridge (22 nm) offers, as did its predecessor Sandy Bridge (32 nm), high performance and lots of features.

The potent quad-core models 3610QM, 3720QM and 3820QM have a TDP of 45 W and place themselves between the frugal 3612QM (35 W TPD) and the luxurious 3920XM (55 W TPD). Six or eight MB L3 Cache (depending on the model) is also respectable. Thanks to the hyperthreading technology, the quad-cores can process up to eight threads simultaneously. The Turbo Boost function allows for a dynamic overclocking.

Schenker has equipped our test unit with the 2.7-3.7 GHz Core i7-3820QM, which costs about 300 Euro (~$377) in the online configurator and provides more than enough power for the SLI combo (the same goes for the cheaper Core i7-3720QM). Purely from a price-performance point of view the Core i7-3610QM is currently most attractive.

Since the notebook lacks graphics switching, the integrated DirectX 11 chip HD Graphics 4000 cannot be used to save power.

处理器

英特尔的Core i7处理器的高端移动级一直占据着相当长的一段时间。目前的Ivy Bridge的（22纳米）提供，作为其前身的Sandy Bridge（32纳米），高性能和大量的功能。

强大的四核3610QM，3720QM和3820QM型号有TDP45 W将自己节俭的3612QM（35 W TPD）和豪华3920XM（55 W TPD）之间的。六，8 MB ​​L3高速缓存（取决于型号）也是可敬的。由于超线程技术，四核处理器可以处理多达八个线程同时进行。 Turbo Boost功能允许一个动态超频。

全球国际货运代理已装备我们的测试样机的2.7-3.7 GHz的Core i7-3820QM，它的价格约为300欧元（〜$377）的在线配置，并提供足够的能力为SLI组合（同样适用于较便宜的酷睿i7-3720QM）。纯粹价格从性能的角度来看，酷睿i7-3610QM是目前最有吸引力的。

由于笔记本没有显卡切换，集成DirectX11芯片HD图形4000不能使用，以节省电力。

Since we have already tested the Single GTX 680M in detail and the GTX 670M is just a higher clocked GTX 570M, we ordered the XMG P722 with a Dual GTX 680M. While AMD's dual GPU solution is called CrossFire, Nvidia uses the term SLI. Together the Radeon HD 7970M and the GeForce GTX 680M are the current notebook reference.

The DirectX 11.1 capable Kepler model is manufactured using the 28nm process (Fermi: 40 nm) and has 4096 MB of GDDR5 video memory, which is tied to a 256-bit wide bus. The clock frequencies are 720 MHz (core) and 1800 MHz (memory).

Otherwise the 100 W GPU supports various technologies. For the gamers most interesting are the PhysX (GPU based physics acceleration) and the 3D Vision (stereoscopic 3D playback on a 120 Hz monitor). Via the HDMI a high resolution picture and sound can be transmitted to an external device.

The SLI combo is spared from the micro stuttering (subjective, due to varying image distances) thanks to the enormous raw power. Only in extremely demanding games, which run at less than 40 fps, does the image rendering feel worse than that of a single GPU. Tip: in order to get the maximum out the SLI combination, one should update the driver every couple of weeks (on the Schenker, Clevo or Nvidia homepage). The system must be restarted if SLI is deactivated.

既然我们已经详细测试了单GTX680M和GTX670M仅仅是一个高频率的GTX 570M，我们点了XMG P722双GTX680M。虽然AMD的双GPU解决方案被称为交火，NVIDIA使用的术语SLI。共同的Radeon HD7970M和GeForce®（精视™）GTX680M是目前笔记本参考。

在DirectX11.1有能力的开普勒模型是采用28nm制程（费米：40纳米）和4096 MB GDDR5显存，这是联系在一起的一个256-bit宽总线。时钟频率的720 MHz（核心）和1800 MHz（内存）。

否则，100 W GPU支持的各种技术。最有趣的是对于游戏玩家的PhysX（GPU物理加速）和3D立体幻镜（3D立体一个120赫兹的显示器上播放）。经由HDMI的高的分辨率的图像和声音，可以被发送到外部设备。

从微观口吃（主观的，由于不同的图像的距离），由于巨大的原始动力是不遗余力的SLI组合。只有在极其苛刻的游戏，在不到40 fps的运行，并在图像的渲染比单一GPU的感觉更糟糕。提示：为了了SLI组合，以获得最大的一个人应该每隔几个星期全球国际货运代理，蓝天或NVIDIA®（英伟达™）主页更新的驱动程序。如果被禁用了SLI系统必须重新启动。

The 240 GB Corsair Neutron GTX was especially exciting for us. The US company challenges the whole SATA III competition with this brand new solid state drive. The integrated LAMD LM87800 controller does an outstanding job, which is obvious from a look at the AS SSD Benchmark.

Thanks to the sequential read rate of 514 MB/s and a sequential write rate of 456 MB/s the Neutron GTX overtakes not only the beloved Crucial RealSSD M4 (479 & 185 MB/s) and the Intel SSD 520 (496 & 288 MB/s), but also the successful Samsung SSD 830 (499 & 401 MB/s). Only the OCZ Vertex 4 (503 & 459 MB/s) is fit to hold a candle to the Corsair model in the write speeds.

Since even small data is transferred extremely quickly (a new record in 4K-64 write test) and the access times are remarkably low (0.08 - 0.1 ms), we are talking about completely successful performance. However, we cannot predict how the Neutron GTX does in terms of longevity. You should always take into account the failure rates when buying an SSD. Some models do relatively poor here (as far as you believe the customer reviews).

In the secondary hard drive slot (2 x 9.5 mm possible) we find a 750 GB HDD. The Seagate Momentus ST9750420AS works at 7,200 RPM, which guarantees a relatively good performance. The CrystalDiskMark showed the SATA II model working at almost 110 MB/s – an above average HDD performance.

中子GTX240 GB海盗船对我们来说是特别令人兴奋的。这家美国公司挑战这个全新的固态驱动器的SATA III竞争。的集成LAMD的LM87800控制器的表现十分出色，这是显而易见的AS SSD Benchmark的看看。

由于连续读速度为514 MB/ s的顺序写入速度456 MB/ s的中子GTX超越不仅心爱的关键的RealSSD M4（479及185 MB/秒）和英特尔SSD520（496和288 MB / s），但也成功的三星SSD830（499和401 MB/秒）。只有OCZ的顶点（503及459 MB/ s）的适合望其项背的海盗船模型的写入速度。

因为即使是很小的数据传输速度非常快（4K-64的新纪录写入测试）的访问时间是非常低的（0.08 - 0.1毫秒），我们说的是完全成功的表现。然而，我们无法预测的中子GTX长寿的。你应该总是考虑购买SSD的故障率。有些型号在这里做的比较差的（只要你相信顾客评论）。

在辅助硬盘驱动器插槽（2 x 9.5毫米），我们发现一个750 GB的硬盘驱动器。希捷ST9750420AS为7,200 RPM，这就保证了比较好的表现。 CrystalDiskMark的显示，几乎110 MB/ s的SATA II模型的工作 - 高于平均水平的硬盘性能。

As can be seen in the comparison table under the review, the SLI performance depends very much on the game itself. Extreme case A: The frame rate is doubled in comparison to single card. This occurred in about half of the 22 games we tested. Extreme case B: The performance is worse than with a single GPU. If a title does not use the second GPU, the corresponding SLI profile is probably missing from the driver. Overall the dual GPU advantage varies extremely.

If you consider our ultra settings (1920 x1080 pixels, maximum details, multiple anti-aliasing) the second GTX 680M brings about 50% more power. AMDs fiercest rival, the Radeon HD 7970M CF, is at a comparable level, but falls 6% behind in total sum.

The measurements were taken with the current ForceWare 302.77. Even though the driver support is a strength of Nvidia, in some games we noticed peculiarities and/or problems. Here is a short list:

·        Sleeping Dogs, Darksiders II, The Secret World & Dirt Showdown: performance lost or minimal gain ⇒ obviously (still) no SLI profile

·        F1 2011: DirectX 9 mode is slower than DirectX 11

·        FIFA 12: refresh rate limited to 120 fps

·        Modern Warfare 3: short stuttering despite higher performance

·        Batman Arkham City: enormous frame rate fluctuations

·        StarCraft II: the beginning of the benchmark sequence (video at in-game graphics) was unnaturally slow 

在比较表中可以看出，在检讨中，SLI性能在很大程度上取决于游戏本身。极端情况下A：帧速率在单卡相比翻了一番。这发生在我们所测试的22场比赛中的一半左右。极端情况下B：比单GPU性能更糟糕的是。如果标题不使用第二个GPU，相应的SLI的档案可能丢失从驱动程序。总体来说，双GPU的优势差异极了。

如果您认为我们的超设定（1920 X1080像素，最大的细节，多抗混叠）GTX680M带来约50％的电力。 AMD的凶猛的对手的Radeon HD7970M CF，在可比的水平，但下降6％，落后于总和。

测量与当前的ForceWare302.77。即使Nvidia的驱动程序的支持是一种力量，在一些比赛中，我们注意到特点和/或问题。下面是一个简短的清单：

·睡觉的狗，暗黑血统的秘密世界II及污垢摊牌：性能丢失或最小增益⇒明显（仍然）没有SLI配置文件

·F1 2011：DirectX 9模式是慢于DirectX 11的

·FIFA 12到120帧刷新速率限制

·现代战争3：短口吃尽管更高的性能

·蝙蝠侠阿甘之城：巨大的帧速率波动

·“星际争霸II”的基准序列开始在游戏中的图形（视频）不自然地慢

Noise Emissions

The high noise emissions cost the XMG P722 a couple of points. Even in idle state, the three fans are audible. At a distance of 15 cm (5.9 inches), our measuring device showed between 35 and 38 dB(A). The rival Alienware M18x R2 remained quieter at undemanding tasks (~33-34 dB(A) at idle).

Under load the 17-inch notebook is clearly audible. With almost 44 dB(A), the fans were a bit quieter during 3DMark 06 than in the Alienware notebook (~42 dB(A)). For some users the noise levels would already be slightly disturbing. Those who usually play with headphones and/or play sound intensive genres (FPS, racing, etc.) should be able to handle the noise. Under unnatural full load the XMG P722 is quite uncomfortable: Our stress test registered more than 50 dB(A).

噪音排放

高噪声排放的成本XMG P722几个百分点。即使是在空闲状态下，三个风扇都可以听到。在15厘米（5.9英寸）的距离，我们的测量设备显示，35至38分贝（A）。对手的Alienware M18x R2保持安静的在要求不高的任务（33-34分贝（A）在空闲时）。

根据负载的17英寸笔记本电脑是清晰可闻。近44分贝（A），球迷们有点安静的在3DMark 06的比Alienware的笔记本电脑（约42分贝（A））。对于一些用户的噪音水平已略有不安。那些平时玩耳机和/或播放声音密集的流派（FPS，赛车等），应该是能够处理噪音。在不自然的满负荷XMG P722是挺不舒服的：我们的压力测试注册超过50 dB（A）。

The temperatures are also not optimal. After an hour under full load with the tools FurMark and Prime, the Core i7-3820QM reached about 100 °C. The CPU Turbo was active even under these extreme conditions.

The graphics cards on the other hand left us with mixed feelings. Despite the core throttling (360 instead of 720 MHz), one of the GTX 680M reached almost 95 °C. The other GPU stayed much cooler at 74 °C. Under normal 3D programs such as the Unigine Heaven Benchmark the clock frequencies remained at the maximum. Over 90 °C is not to be expected in real (gaming) every day use. Regardless, the one kilogram heavier Alienware M18x R2 wins this category as well (stress test: up to 87 °C). 

The temperatures of the case surfaces are moderate. Almost 30 °C in idle state is properly low for a strong high-end notebook. Under load the chassis reaches 36 °C, whereby the left palm rest is a bit on the higher side.

温度也不是最优的。经过一个多小时的工具FurMark进行和总理在满载情况下，酷睿i7-3820QM达到约100°C。即使在这些极端条件下的CPU Turbo的活跃。

图形卡另一方面，怀着复杂的心情离开了我们。尽管核心节流（360，而不是720兆赫）的GTX680M，一个几乎达到95℃。其他GPU住的温度在74°C。在正常的Unigine天堂基准的3D节目，如时钟频率保持在最大。超过90°C不被预期在真正的（游戏）每天使用。无论如何，一公斤重的Alienware的M18x R2赢得这个类别，以及（压力测试：高达87°C）。

的情况下表面的温度也适中。一个强大的高端笔记本，将近30°C在待机状态下是正确的。负载下的底盘达到36°C，掌托的偏左是一个较高的一侧位。

The P370EM is the first Clevo barebone in years that has a good sound. The manufacturer has installed two loudspeakers by Onkyo, which are driven by an X-Fi certified sound chip.

The THX software gives the notebook more fullness, clarity, and dynamics. Even though the EAX effects subjectively worsen the sound quality, we were happy with the Sound Blaster console (right picture). The bass is fairly strong thanks to the integrated subwoofers. The higher maximum volume also deserves praise: The 2.1 system can fill even larger rooms.

The barebone cannot achieve the title “Sound Reference” though. For a very good sound, the loudspeakers need to be a bit more precise. As a high-quality sound alternative we would recommend the MSI GT70.

该P370EM是第一年，蓝天准系统具有良好的声音。制造商安桥，这是X-Fi认证的音效芯片驱动已经安装了两个扬声器。

THX软件使笔记本电脑更丰满，清晰度和动态。即使EAX效果主观的音质恶化，我们很高兴的Sound Blaster控制台（右图）。低音是相当强的整合式重低音。较高的最大音量也值得称道：2.1系统可以填补更大的房间。

准系统无法实现的标题是“声音参考”了。一个很好的音质，扬声器需要一个更精确的。作为一个高品质的音效选择，我们建议的MSI GT70。

Despite the powerful 8-cell battery (89 Wh, 5900 mAh), the high-end notebook isn't a pretty picture off the socket. So the Reader's Test ran, even at the lowest brightness, only three hours. 2.5 hours of WLAN browsing (medium brightness) and two hours of DVD playback (maximum brightness) are also not amazing.

A bit of a surprise was the Classic Test of the Battery Eater: 108 minutes are rare for a desktop replacement. Why is the score above average? Quite simple: The graphics cards are massively downclocked when using the battery. The reviewed configuration of the Alienware M18x R2 generally did not manage more than two hours.

尽管功能强大的8芯电池（89瓦时，5900毫安时），关闭插座的高端笔记本电脑是不是一个漂亮的图片。因此，“读者”的测试运行，即使在最低亮度，仅三小时。 2.5小时WLAN浏览（中等亮度）和DVD播放两个小时（最大亮度），也没有惊人的。

一个有点意外的经典测试的电池食：108分钟是罕见的台式机替代品。得分高于平均水平，为什么？很简单：图形卡大量使用电池时downclocked的。审查的Alienware M18x R2的配置一般不管理了两个多小时。

Compared to the old X7200 barebone, the chassis manufacturer Clevo makes a big step forward. Thanks to the lack of a desktop CPU, the P370EM boasts a more compact cooling solution, which allows for a slimmer and lighter chassis. The XMG P722 PRO is still not particularly portable though. Depending on the equipment, the 17-inch notebook weighs about four kilograms. The high-end notebook is primarily suited for stationary use.

A great advantage of the Clevo device is the simple maintenance. Nearly every component can be unscrewed and replaced (possible loss of warranty). Most users however, can find the right hardware in the extensive configurator. It is also great that the good non-glare display is accompanied by a useful sound system. In addition there is the good connectivity (including 4 x USB 3.0), a high-quality backlit keyboard, and a clean Windows installation. The outstanding performance has already been discussed in detail.

On the negative side are the sensitive and somewhat tacky touchpad as well as the average battery life and incredibly massive power supply. The emissions were also not good. Under load the components became quite hot. In terms of noise, one should not expect anything: Like most 17-inch gaming notebooks, it is not very quiet.

If you have taken a look at the Alienware M18x R2: The 18-inch notebook is better at the input devices, the connectivity, the emissions, and the workmanship. Disadvantages include the larger and heavier chassis, the highly reflective display, and the expensive upgrades.

But whether it is Schenker or Alienware: A similarly powerful and well-equipped gaming PC can be built for half or even a third of the price. But this should hardly stop the notebook enthusiasts.

相比老X7200准系统，机箱制造商蓝天使前进了一大步。由于缺乏桌面CPU，P370EM拥有一个更紧凑的冷却解决方案，该解决方案允许更薄更轻的机箱。 XMG P722 PRO特别是便携式虽然还没有。根据不同的设备上，17英寸的笔记本重约四公斤。主要适用于固定使用的高端笔记本。

蓝天设备的一大优势是简单的维护。几乎每一个组件都可以拧开，并可能失去保修更换（）。然而，大多数用户广泛的配置，都可以找到合适的硬件。也很大，伴随着一个有用的音响系统的良好的无眩光显示。此外，还有良好的连接（包括4×USB 3.0），高品质的背光键盘，以及一个干净的Windows安装。的出色表现已经详细讨论。

在消极的一面是敏感的，有点俗气的触控板以及电池的平均寿命和令人难以置信的大量的电源。的排放量也并不好。根据负载的组件变得非常热。在噪音方面，不应该期望什么：最喜欢的17英寸游戏笔记本，它是不是很安静。

如果你看看Alienware的M18x R2：18英寸的笔记本电脑是更好的输入设备，连通性，排放和做工。缺点包括较大和较重的机箱，高度的反射型的显示，和昂贵的升级。

但无论是全球国际货运代理或Alienware的游戏PC可以建立一个同样强大的装备精良的一半甚至三分之一的价格。但是，这应该很难停下来的笔记本爱好者。
