英特尔Ivy Bridge的玩家指南

Weighing in at just less than 3.2 kg (~7 pounds), the Schenker XMG P502 PRO, which is based on the P150EM Barebone made by the Taiwanese manufacturer Clevo, is ideally suited for graphics card and CPU tests alike, thanks to its user-friendly design. Hidden inside the chassis of the 15.6-inch gaming notebook we find Intel's modern H77 chipset.

For the purpose of this review, we opted for 8 GB of DDR3 RAM (2 x 4096 MB in dual channel mode), along with a 320 GB HDD running at 7200 RPM. The operating system (Windows 7 Professional 64-bit) was up-to-date, of course. As a GPU driver we enlisted the ForceWare 306.02 Beta because the WHQL-certified version 306.23 arrived just a bit too late.

在短短不到3.2公斤（7磅），全球国际货运代理XMG P502 PRO，这是由台湾制造商蓝天的P150EM准系统的基础上，非常适合显卡和CPU的测试一样，由于其用户人性化的设计。隐藏在机箱内的15.6英寸游戏笔记本，我们发现英特尔的现代H77芯片组。

这篇评论的目的，我们选择了8 GB的DDR3内存（2×4096 MB在双通道模式下），连同一个320 GB硬盘转速为7200 rpm。 Windows 7专业版操作系统（64位）是最新的，当然。作为GPU的驱动程序，因为我们邀请的ForceWare306.02 Beta版WHQL认证的版本306.23刚刚到达有点晚了。

Let's cut to the chase and get straight to the most interesting aspect: performance. The five chosen games cover almost the entire range. There's a racing game (Dirt Showdown), a member of the role-playing family (Skyrim), a popular action hit (Battlefield 3), a brand-new MMO (Guild Wars 2), and one of the last highlights of the floundering strategy genre (Shogun 2). Judging by our previous experience and/or other tech benchmarks, these titles all benefit from a strong CPU.

In order to guarantee a high degree of practical relevance, we have opted for graphically demanding settings. While lower configurations might reveal the differences more clearly, let's be honest: who would want to run their high-end GPU at 1366x768 pixels and medium level details? Hence, every game was run at 1920x1680 pixels and high to maximum graphics options (sometimes including anti-aliasing). To reduce variability, each benchmark was performed twice, and the average of both runs is listed in our tables.

Before we'll look at the results, a word of caution: while the weaker of the quad-core models i7-3610QM and i7-3612QM, as well as all dual-core processors, ran at around 200 MHz below their Turbo maximum, the quad-core i7-3720QM and i7-3820QM sometimes approached their base frequencies. According to Schenker, the problem also affects the top-end Core i7-3920XM model. What does this mean in terms of our comparison? Well, the two fastest quad-cores may be performing below their true capabilities, so results should be taken with a grain of salt.

让我们切入正题，并获得直接最有趣的方面：性能。选择游戏几乎覆盖了整个范围。没有一个赛车游戏（污垢对决），一个成员的角色扮演家庭（天际），一个流行的动作命中（战地3），一个全新的MMO（激战2），和的最后一个亮点了苦苦挣扎的战略游戏（幕府将军2）。从我们以往的经验和/或其他高科技基准，这些头衔都将受益于强大的CPU。

为了保证高度的实际意义，我们选择了为图形要求设置。虽然较低的配置可能会更清楚地揭示了不同，说实话，谁愿意来运行他们的高端GPU为1366×768像素，中等水平的详细信息？因此，每场比赛都运行在1920x1680像素，高最大的图形选项（有时还包括抗锯齿）。为了减少可变性，每个基准进行两次，并都运行的平均值是在我们的表列出。

之前，我们将看到的结果，一个字谨慎，而较弱的酷睿i7-3610QM和i7-3612QM，以及所有的双核心处理器的四核机型，运行在200 MHz以下的涡轮增压最大，四核心的酷睿i7-3720QM和i7-3820QM有时接近其基频。根据全球国际货运代理，这个问题也影响到最高端的酷睿i7-3920XM模型。我们比较这意味着什么？好了，最快的两个四核处理器可能会表现低于他们的真实能力，因此应采取与一粒盐。

The fact that the CPU plays quite a major role in Guild Wars 2 should be nothing new to many readers. Still, just how massively the choice of CPU impacts performance, was a surprise even to us. The difference between the cheapest dual-core Core i3-3110M (no Turbo Boost technology) and the expensive Core i7-3820QM was a whopping 23 fps. The popular MMO doesn't just scale with clock speed, but also with the number of cores - a rare sight.

Our benchmark sequence (1920x1080, Best Appearance preset) required a Core i5-3320M in order to run at more than 30 fps. More than 40 fps was the exclusive realm of quad-core models. In summary, a dual-core is enough for playability, but an optimum result requires a laptop equipped with a quad-core CPU.

事实上，的CPU中起着很重要的作用，在激战2应该没有什么新的许多读者。不过，大量CPU的选择会影响性能，甚至给我们一个惊喜。最便宜的双核酷睿i3-3110M（无Turbo Boost技术）和昂贵的酷睿i7-3820QM的区别是高达23帧。流行的MMO不只是规模与时钟速度，但也与一些核心 - 难得一见的景象。

我们的基准序列（1920×1080，外观预设）规定了酷睿i5-3320M，以运行在每秒30帧以上。超过40 fps的四核机型的专属领域。总之，双核是不够的可玩性，但需要一台笔记本电脑配备了一个四核CPU的最佳结果。

The action-packed Dirt Showdown is mainly concerned about the number of cores. Even though all dual-cores were able to render 1920x1080 pixels, four times anti-aliasing and the Ultra preset, subjectively the gameplay did not always feel smooth. With a quad-core, Showdown always runs smoothly, no matter what the clock speed (this applies to Intel only).

动感十足的污垢摊牌主要是关注的核心数量。即使所有的双核心能够提供1920×1080像素，4倍抗锯齿和超预设，没有主观的游戏总是感觉光滑。随着四核摊牌始终运行顺畅，不管是什么时钟速度（适用于英特尔只）。

In Skyrim, the entire Ivy Bridge range did well. While we were able to measure certain differences in 1920x1080 and Ultra settings, we don't expect these to be noticeable in practice. The attractively priced Core i5-3210M and the potent Core i7-3820QM were separated by a mere two fps. Again, the Core i3-3110M trailed slightly.

在天际，整个Ivy Bridge的范围做得很好。虽然我们能够测量在1920×1080和Ultra设置一定的差异，我们并不指望这些在实践中是明显的。价格极具吸引力的酷睿i5-3210M和强有力的酷睿i7-3820QM分离的只有两帧。同样，酷睿i3-3110M稍微落后。

For Battlefield 3, we made use of our well-proven benchmark routine. The linear sequence of events during the single-player mission "Operation Swordbreaker" ensures a good reproducibility. Because this passage includes little physics which makes it quite GPU-heavy, the Ivy Bridge models all ended up on pretty much the same level. 1920x1080 pixels and the "High" preset resulted in 49-51 fps. In giant multiplayer battles with dozens of opponents, vehicles, and destructible objects (difficult to measure due to the variable gameplay), the difference should be larger.

“战地3”中，我们利用我们经过充分验证的基准程序。在单人游戏任务“操作Swordbreaker事件的线性序列”，保证了良好的重现性。由于这个通道包括一点物理这使得它很GPU重，Ivy Bridge的型号都结束了几乎相同的水平上。 1920×1080像素的“高”预设在49-51帧。在巨大的多人对战几十个对手，车辆和破坏的对象（难以测量的变量的游戏），差异应该更大。

Although Shogun 2 includes a dedicated CPU benchmark, we prefer to rely on the standard graphics test (Benchmark DX11 Graphics High 1080p). Firstly, the CPU test only runs under DirectX 9. Secondly, even a Core i7-3610QM only manages a meager 20 fps. And thirdly, the graphics benchmark looks more realistic to us, thanks to its camera pans and the changes between close-up and bird's eye perspectives.

But back to topic: like in Battlefield 3, most Ivy Bridge CPUs saw eye-to-eye in terms of performance. At 47 fps, the  Core i3-3110M came in minimally slower than its siblings that managed an average of 48-49 fps. The same is true for the minimum fps value, whose importance should not be underestimated. Only during Dirt Showdown and Guild Wars 2, were considerable differences showing in this respect, in line with expectations given the average values.

虽然幕府将军2包含一个专用的CPU基准测试，我们更倾向于依靠标准的显卡测试（基准测试DX11显卡的高1080P）。首先，CPU测试只能运行在DirectX9。其次，即使是酷睿i7-3610QM管理的微薄每秒20个画面。第三，图形基准测试看起来更加现实的我们，要归功于它的摄像头锅和特写镜头和鸟瞰的角度之间的变化。

但是，回到主题：在“战地3”一样，大部分的Ivy Bridge的CPU看见眼睛对眼睛方面的表现。在47 fps的，酷睿i3-3110M是在微创比它的兄弟姐妹，管理48-49 fps的平均慢。同样是真实的最小FPS值，其重要性不应该被低估。只有在灰尘摊牌和激战2中，相当大的差异，在这方面，与预期的平均值。

The total consumption of the system was measured directly at the power socket (Voltraft VC 940). While the dual-core equipped notebook took up between 120 Watts (i3-3110M) and 130 Watts (i7-3520M) on average during Battlefield 3, the quad-core configurations allowed themselves between 126 Watts (i7-3612QM) and 138 Watts (i7-3820QM) by the same measure. Overall, power consumption varied by about 20 percent, which seems acceptable, given the performance difference.

在电源的插座（Voltraft VC940），系统的总消费量的直接测量。虽然配备双核笔记本之间平均120瓦（酷睿i3-3110M）和130瓦（酷睿i7-3520M）在“战地3”，让自己的四核配置126瓦（酷睿i7-3612QM）和138瓦之间（酷睿i7-3820QM）相同的措施。总体而言，电力消耗的20％左右，这似乎是可以接受的，因为性能上的差异变化。

During our temperature measurements, we relied on the CPUID Hardware Monitor. According to the well-known tool, the quad-cores heated up a bit more than their dual-core counterparts. Except for the most power-efficient 35 Watt model i7-3612QM, all quad-cores reached temperatures above 70 °C during Battlefield 3. By contrast, a majority of the dual-cores remained below the 70 °C threshold. Thanks to the separate cooling cycles, the GPU was largely unaffected. Depending on the CPU, the GeForce GTX 680M reached between 80 °C and 86 °C. Specially applied thermal grease Prolimatech PK-1 was used as a cooling agent.

在我们的温度测量，我们依靠的CPUID硬件监视器。根据著名的工具，加热四核比双核心多一点。除了为最节能的35瓦型号酷睿i7-3612QM四核达到70°C以上的高温，在“战地3”。与此相反，大多数的双核仍低于70℃的阈值。由于单独的冷却周期，在GPU基本上不受影响。根据不同的CPU，GeForce®（精视™）GTX680M之间达成的80°C和86°C。专门用于导热油脂Prolimatech PK-1用作冷却剂。

As you can see from the table, the choice of CPU had at most a minimum impact on the system noise. Whether a weak dual-core or a powerful quad-core was fitted, after 15 minutes of Battlefield 3, the XMG P502 PRO emitted a clearly audible 47 dB (Voltcraft SL 320, 15cm (~6 inches) distance). In desktop replacement laptops, the noise is mainly determined by the graphics card.

从表中可以看到，CPU的选择，最系统的噪声影响降到最低。无论是微弱的双核或一个强大的四核心的“战地3”15分钟后，被装，XMG P502 PRO发出一个清晰可闻的47分贝（的VOLTCRAFT SL 320，15厘米（6英寸）的距离）。在台式机替代品笔记本电脑，噪音主要是由显卡。
