英特尔Ivy Bridge的四核刷新测评

Altogether 5 new quad-core processors from the i7 series are supposed to extend Intel's product range starting from today. In all cases, the new editions are direct successors of previous models, which merely have a 100 MHz faster processor (base as well as Turbo clock speed) and a 50 MHz faster GPU (only Turbo) compared to their predecessors.

For the first time in years Intel has now got a CPU with a minimum base clock speed of 3.0 GHz in their lineup: the Core i7-3940XM now supersedes the 3920XM as the fastest mobile processor, and therefore promises improved peak performance results from our tests. Too much shouldn't be expected though: considering the marginally higher clock speed, the performance improvement should be limited to between 2 and 4%, including the "smaller" i7-3840QM, i7-3740QM and i7-3630QM models. Below is an overview of the specifications, along with links to the descriptions in our CPU database. 

共有5个新的四核处理器i7系列应该扩大英特尔的产品范围，从今天开始。在所有的情况下，新的版本是直接的继任者以前的型号，只是有一个100 MHz的速度更快的处理器（基地以及睿频时钟速度）和一个50 MHz更快的GPU（仅涡轮增压）与他们的前辈相比。

对于多年来第一次，英特尔现在得到了在他们的阵容中最低的基本时钟速度为3.0 GHz的CPU：酷睿i7-3940XM取代3920XM最快的移动处理器，并承诺改进的峰值性能，从我们的测试结果。不应该过多预期，但：，考虑轻微更高的时钟速度，性能的提高，应限制在2至4％，其中包括“小”的酷睿i7-3840QM，酷睿i7-3740QM和i7-3630QM模型。下面是一个简单规格，以及链接到我们的CPU数据库中的描述。

Also new is the successor to the only 35 watt quad-core in the lineup, the Core i7-3612QM. The Core i7-3612QM now operates at 2.2 and 3.2 GHz, and is able to clock its GPU at a maximum of 1150 MHz. Unfortunately we will have to leave the benchmarks results for this model outstanding for now.

Before we take a look at the results, we would once again like to point out that our benchmarks were performed with pre-serial production CPUs - especially with regard to the power consumption, it cannot be entirely ruled out that there may be small differences compared to regular serial production models. In addition to this, many processors can also be delivered with different VIDs (supply voltage identification), which results in additional scope for tolerances.

之前，我们需要看看结果，我们会再次想指出，我们的基准进行执行前的串行生产的CPU - 尤其是对功耗，它不能完全排除了，有可能是小的差异比较正常的串行生产模式。除了这一点，许多处理器也可以传递不同的VID（供应电压识别），这会导致额外的公差范围。

Cinebench R10 as well as the more up to date Cinebench R11.5 are both separated into a single- and multi-thread test, allowing for a detailed analysis of performance to be ascertained. As expected, the i7-3940XM outperforms in all the tests, while the lead compared to the other quad-cores is partially only marginal. The laggard is the i5-3210M, which has to forgo half the cores as well as a few hundred MHz of clock speed.

CINEBENCH R10，以及最新的CINEBENCH R11.5都分为单和多线程的测试，允许的性能进行详细的分析，才能确定。正如预期的那样，酷睿i7-3940XM的性能在所有的测试，而铅相比其他四核部分是有限的。落后的是酷睿i5-3210M，放弃一半的核心以及几百MHz的时钟速度。

The benchmark x264 HD measures the performance while encoding a video into the popular H.264 format. The Pass 2 test especially makes intensive use of all the available cores as well as Hyper-Threading. Altogether the results from the previous Cinebench results are more or less validated: the top model Core i7-3940XM leads the way, quickly followed by the 3840QM and the 3740QM. Just how marginal the performance improvement turns out to be in practice is demonstrated by a comparison between the 3610QM and the 3630QM: less than 4% separates the CPUs from each other.

X264 HD基准测量性能，同时为流行的H.264格式编码的视频。第二遍测试，尤其是集约利用所有可用的核心以及超线程。共有CINEBENCH结果从以前的结果都或多或少验证的顶级型号Core i7-3940XM的领路人，紧接着3840QM和3740QM。究竟边缘性能的改进是在实践中被证明3610QM和3630QM之间的比较：小于4％，从相互分离的CPU。

Futuremark's 3DMark series is not only suitable for assessing the graphics performance, but also allows CPU performance measurements to be made with the aid of special tests. Once again, the differences between all the counterparts are minimal, although the dual-core i5-3210M is clearly left behind.

In practical gaming scenarios it is difficult to demonstrate the full performance potential of fast quad-core processors, even with the most powerful notebooks that are available at present. The frame rates of most games - at least with realistic settings - are stipulated by the GPU; hence we have forgone the relevant benchmarks at this juncture. In this case, however, there are also a few exceptions, such as KI intensive strategy games or simulations, for which an especially fast CPU can be an advantage.

Futuremark的3DMark系列不仅适用于评估的图形性能，但也使CPU性能测试，借助特殊的测试。再次，所有同行之间的差异是微乎其微的，虽然双核心的酷睿i5-3210M显然是留下。 

在实际游戏的情况下，它是很难表现出快速的四核处理器的全部性能潜力，即使是最强大的笔记本电脑，目前已有。大多数游戏的帧速率 - 至少与现实的设置 - 所规定的GPU，因此在这个时候，我们放弃相关的基准。然而，在这种情况下，也有一些例外，如KI密集的战略模拟游戏或特别快的CPU，这可能是一种优势。

Since the introduction of Turbo Boost it is certainly not a simple task to compare the power consumption of different CPUs with each other. In addition to this, Intel also allows its processors to briefly exceed their TDP, which brings another variable into the equation. For this reason we have taken an especially detailed look at this topic on this occasion, and have also tried to incorporate the dynamics of the Turbo Boost into the picture.

As with our previous tests, we measured the power consumption of the whole notebook behind the AC adapter, which is why only the relative results of the various CPUs should be evaluated, and not the absolute values.

由于采用睿频加速它肯定不是一个简单的任务相互比较不同的CPU的功耗。此外，英特尔还简要超过允许其处理器的TDP，这带来了另一个变量代入公式。为此，我们采取了一个特别详细的看看这个主题在此之际，也试图把的Turbo Boost动态的图片。

与我们之前的测试中，我们测得的功耗背后的整个笔记本电脑AC适配器，这就是为什么相对应的不同的CPU进行评估，而不是绝对值。

During the multi-thread test in Cinebench, the capability available for the first time since Sandy Bridge for the specific TDP to be exceeded for about 25 seconds becomes obvious. In this case, this only applies to the three fastest of the contenders: Core i7-3940XM, 3840QM and 3740QM. Only due to this are these models able to fully utilize the enormous Turbo Boost potential.

One thing becomes clear from this insight, which is not sufficiently obvious judging from the above, usually rather short, benchmarks: after prolonged utilization the performance differences between the i7-3630QM, 3740QM and 3840QM become even smaller than they already are. Within 45 watts TDP, only the 3630QM (as well as the older 3610QM) is able to sustain its maximum clock speed with a practically full utilization consistently. The 10 watt higher TDP is an advantage for the i7-3940XM, which allow the processor - assuming sufficient cooling - an additional several hundred MHz.

在Cinebench里，对于特定的TDP的Sandy Bridge以来首次超过约25秒变得明显的能力可用于在多线程测试。在这种情况下，这仅适用于最快的三个竞争者：酷睿i7-3940XM，3840QM，3740QM。由于这是这些模型能够充分利用巨大的Turbo Boost的潜力。

有一件事情变得清楚的洞察力，这是不十分明显的，从上面的，通常比较短，基准来看：经过长时间的利用之间的性能差异酷睿i7-3630QM，3740QM，3840QM他们已经是变得更小。在45瓦的TDP，只有3630QM（以及老3610QM）是能够承受的最大时钟速度与实际充分利用一贯。更高的10瓦的TDP是一个优势的酷睿i7-3940XM，它允许处理器 - 假设有足够的冷却 - 一个额外的几百MHz。

A similar situation can be observed with Prime95, only that the generally higher utilization with all the tested quad-cores leads to a throttling of the Turbo Boost after a few seconds. Compared to the predecessor models, the power consumption seems to have hardly changed in any case, as the comparison between the Core i7-3630QM and the 3610QM shows.

可以观察到类似的情况Prime95的，只是所有被测试的四核处理器的利用率普遍较高，导致一个节流的Turbo Boost几秒钟后。的前身模型相比，功耗似乎几乎没有改变，在任何情况下，作为比较的Core i7-3630QM和3610QM节目之间。
