Crysis摆下比武台，新老CPU谁是真英雄？

Notice: We have done a re-test based on the earlier episode on these CPU due to the driver and system setting reason.

These days we using the Crysis built-in benchmark to do some more test on Intel QX9650, QX6850, QX6700, AMD Phenom X4, AMD Athlon64 X2 5000+ and FX62 again. For more accuracy we re-install the whole OS, using the newest driver, and adding some subitem tests.

The test focus on the difference of core architecture, so all the frequency are set to the same. Because the retail version phenom X4 have limited OC ability(multiplier locked) so that we have to use engineering sample.(we can't find any difference except the locked multiplier between ES and retail version)

The same as before, 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.

Round one: A64X2 5000+ VS. A64FX62 VS. Phenom X4 VS. QX6700

QX6700 > Phenom X4 > FX62 > 5000+

Having a bigger L2 cache, FX62 beats 5000+. And the average score of Phenom X4 is 21.5% more than FX62. But, Phenom X4 losing this round coz its final score less than QX6700 for 12.7%. We have to stress that because of the architecture difference, AMD have the memory frequency demultiplication difference between Intel systems: Phenom X4's memory frequency is 485.9MHz (x2),and QX6700 is 400MHz(x2).


Round two: AMD quad core VS. Intel quad core

Click to see E6850 and FX62 score as a refrence

QX9650 > QX6850 > E6850 > Phenom X4 > FX62 (same frequency)

Yorkfield QX9650 only have little improvement compare to Kentsfield QX6850, only 1.4%. But quad core QX6850 beats E6850 by 13.7% improvement.

Comparing to the AMD side: native quad core Phenom X4 wining FX62 by only having 17.7% improvement, Far less than E6850.

comparing to QX9650, Phenom X4 have a huge gap(21.2% less)


Round three: Overclocking, and HT link

For finding more info to detect the Phenom X4 performance, we continue on several OC test. From the final score, the HT frequency have no actual boost on Phenom X4's performance.


Final thoughts:

Testing using Crysis CPU Benchmark is a new try, We hope this test can show the CPU's actual performance.

With these score AMD can't win this fight easily. We know that the OC ability of these retail version AM2+ CPUs are limited. We can not use the multiplier to OC, and using FSB to OC only can boost up the frequency for 26X～27XMHz. Pls remember that a easily-OC-to-3GHz-PhenomX4 wont sell on market.

It is not the Frequency limiting the Phenom X4. Just read all the score for reference, Even OC to the same frequency Phenom still can not win. Compare to dual core E6850 it still have a performance gap.

But the test also show some bad news for Intel: the dual-core-to-quad-core improvement are more less than AMD's job. AMD is catching up and Intel still using their last generation advantage.

We want to ask AMD: where's native quad core's advantage? Nov.20 Phenom X4 will begin selling, at that time we will know more.
