性能总结——综合性能：

性价比：

价格：

教大家如何看这个性价比坐标轴：首先找到你所关心的价位，比如你要选择100美元（700RMB）左右的CPU，那么你就在横轴（标有价格的轴）上找到100美元的对应位置。然后以这个位置为原点，往上看，纵轴代表性能，在100美元这条纵轴上，性能越高的CPU，表明它的性价比越高

综合性能-价格比：

游戏性能-价格比：

媒体性能-价格比：

渲染性能-价格比：

每瓦特性能（性能/功耗比）：
每瓦特性能代表了这个CPU的能耗比，越高表明它完成一份工作所消耗的能源越少

每Hz性能（性能/频率比）：
性能频率比这个指标一般来说可以作为超频后性能提升幅度的参考，可以看到，在超频幅度相同的情况下，在Intel C2D CPU上所获得的性能提升要远远超过速龙CPU

The diagram shows very well that CPUs with Core micro-architecture can process more instructions per clock cycle than K8 processors. That is why Athlon 64 X2 should work at about 20% higher frequency in order to catch up with Core 2 Dup E4000 or Pentium E2000 performance.（这就是为什么A64 X2必须拥有20%的频率优势才能提供和E4000/E2000一样的性能的原因）

And in order to compete against Wolfdale, AMD K8 processors should run at 40% faster frequency（为了和 Wolfdale竞争，AMD A64 X2处理器必须提供比同档次Wolfdale高40%的频率）, which is simply impossible today. That is why the today’s Athlon 64 X2 simply cannot compete against new dual-core Core 2 Duo E8000 processors at all.

In fact we have already shared all the conclusions that can be made basing on the results obtained during this test session. So, now we will simply sum everything up stressing the most important things.

So, new Intel Core 2 Duo E8000 processors based on 45nm Penryn cores do not have any worthy competitors at this time. They are considerably faster than Core 2 Duo with smaller model numbers and outperform the top AMD Athlon 64 X2 CPUs with overwhelming advantage. Add here their fantastically low power consumption and pretty democratic official pricing and Core 2 Duo E8000 will turn into a potential market hit. It is especially true for Core 2 Duo E8200 and E8400 models.

Only retailers can cast a shadow over this rosy situation, because they keep the prices for these promising models at a pretty high level since the market hasn’t been saturated with them just yet. However, this problem should very soon get resolved.

As for the top Athlon 64 X2 processors, they turned out seriously overpriced after the launch of the new Core 2 Duo E8200. Today they can only compete against Core 2 Duo E4000 and Pentium E2000. Moreover, we can check out how reasonable AMD’s price policy actually is with a simple empirical rule: for AMD Athlon 64 X2 processor to perform as fast as a Core 2 Duo E4000 or Pentium E2000, it should run at about 20% higher clock speed.

It means that from the performance standpoint AMD Athlon 64 X2 6000+ should cost as much as Core 2 Duo E4600, and Athlon 64 X2 5000+ shouldn’t be priced higher than Pentium E2200.[这意味着，从性能价格比角度来讲，X26000+的价格应该要和E4600持平，而X2 5000+的价格也不应该高过E2200（这样才能保持相同的性价比）] Only in this case the dual-core processors pricing would be considered fair and reasonable. Moreover, we will have to disregard the power consumption rates in this case, because regular Athlon 64 X2 cannot be considered economical.

So, the results of our today’s dual-core processor shoot-out indicate clearly that Intel processors win the “Best Buy” title in every single price segment.（所以，我们的测试结果，表明了现在Intel的双核心处理器在任何价位都赢得了“最值得购买”的称号） And it will remain this way until AMD reduces the prices on its Athlon 64 X2, which keep rapidly losing their appeal. The situation may also change if they launch revised triple-core and dual-core processors on Phenom-like architecture, whiave a chance of become more competitive against Core 2 Duo. However, it will hardly happen any time soon.

如果有人能做个超频后的测试就好了。这才有实际意义。
不是BT的极限测试。

例如加入3.2G 的2140之类的。。。（比6400+的成绩还快10%以上？？？）

现在还有人买2140不超频的么？？？:unsure:

个人买的可能会超频，电脑盲和单位的机器就不超频的。:lol:

:blink: amd不做k10内核的双核是不是已经放弃抵抗了。还是k10就是k8x4加l3 ?

你嫌AMD输得不够惨？

70%以上不会超频的
我周围一群人只有我一个超CPU 显卡的(_(

intel只有高端厉害
地段的如果没人超频那还是AMD .
我很想玩玩E1200
