Phenom X4 vs. Yorkfield tested in Crysis at 3Ghz

Also thrown in for comparison was an Intel Core 2 Duo E6850 and a Core 2 Extreme QX6850. As you might have already realised, the Intel chips are clocked a fair bit higher than the Phenom X4, so to make things a bit more even, the Phenom X4 was overclocked to 3GHz.

This is still not quite a fair comparison, as the Phenom X4 had it's memory running at 375MHz due to limitations of AMD's integrated memory controller which prevented it to run at 400MHz as per the Intel based test systems. The Phenom X4 system also had a lower bus speed, due to Intel's move to 1,333MHz bus.
