在昨天的《Crysis摆下比武台，新老CPU谁是真英雄？》一文后，很多朋友希望了解更加传统的一些测试，之前我们已经跑过Superpi，现在我们花一些时间进行最经典的测试——3Dmark06，由于时间有限，所以只是进行默认设置的测试。
本次测试旨在说明的是不同核心的性能差异，因此频率都被定制为一样的3GHz。锁定倍频的零售Phenom X4超频能力极为有限，所以测试一直用一颗不锁倍频的工程样品代替。
测试系统方面，AMD平台使用即将发布的RD790，而Intel平台则使用P35主板，包括游戏在内的所有设置都是默认。显卡是GeForce8800GTX，驱动是最新的169.02，板载声卡使用了Realtek 1.80驱动，操作系统是Windows XP(DX9)。
设置时，内存均设置为“by SPD”(by SPD= 5-5-5-18)，但CPU-Z侦测Phenom X4平台时会误辩为5-5-7-18，这个问题要等CPU-Z以后的更新解决了。AMD系统的内存频率是375MHz(X2)，这是由于AMD的内存频率与主频挂钩的原因，不然就要运行在428MHz(X2)，我们选择了比较接近DDR2-800的频率。
| 特别说明：为什么Phenom X4的CPU-Z图中内存显示为单通道？
因为此时打开Phenom X4的2个内存控制器，1个内存控制器控制一条内存，这样在执行多任务的表现会更好,但是提升并不是很大，这只是对AMD平台稍做优化而已。 |
从成绩来看，Phenom X4总分只是落后QX6850 5.5%，然而CPU Score却落后达9.11%，参照对象如果更换为QX9650，数值会更大一些。如果要从其他子项目的成绩来看，双核的E6850显然比Phenom X4更能发挥图形系统的效能。Phenom X4相对E6850中获得的7.17%的总分领先优势都是从CPU得分取得的。
事实上，现在多数游戏对多核优化远没有3DMark06 CPU 测试来得高，接下来你看到的一些测试可能会显示，双核的Core2处理器比Phenom X4表现更好，这并不是让人意外的情况。我们不得不提醒，Phenom X4并不是容易就能超到3GHz。Phenom X4即将发布的最高型号是9700，它的频率是2.6GHz。你要知道，并不是AMD不想直接推出超过3GHz频率的产品。
Part 3：playing Phenom X4 with 3Dmark06
After last week's Superpi (part 1) and yesterday's Crysis benchmark (part 2), some of our readers want to see 3Dmark06 result. And here it is.
All this tests are run in default setting.
The test focus on the difference of core architecture, so all the frequency are set to the same. As before, we are using a unlocked ES version Phenom X4.
In AMD test bed we are using the up-coming RD790 mobo. And in Intel test bed we are using P35. Including games, all the setting are in default. We are using GF 8800GTX,Driver is 169.02 WHQL. integrated Soundcard using Realtek 1.80 driver, and OS is XP SP2(DX9).
We set all the memory to "By SPD"(by SPD= 5-5-5-18). But when we are using the Phenom X4 platform, CPU-z wrongly detected the timing as 5-5-7-18. Please wait for the CPU-Z's further update. The AMD test bed's memory frequency is 375MHz(x2). We already know the issue.

Why CPU-Z shows Phenom X4 only have single channel? |
From the final result, Phenom only lose QX6850 about 5.5%. But the CPU Score is losing 9.11% . If the rival change to QX9650, the gap will even bigger. If we compare to other subitem, that dual core E6850 will boost Graphic system better than Phenom X4. Comparing to Phenom X4 and E6850, All the advantage score are coming from the CPU score. Phenom X4 does bad in HDR and SM subitem tests.
In fact, LOTs of games are are not have the enough dual core or quad core optimize than 3Dmark06. In other test, you may find out even a dual core Core 2 is better than Phenom X4. That means not enough optimize support for our Phenom X4.
Remember the highest version of Phenom X4 is 9700, and it's frequency is only 2.6GHz. AMD wont let 3GHz out that easliy.
