Update: The original Company of Heroes results we recorded showed the Intel Core 2 Quad processors delivering unusually high performance. Having run the tests several times we could not work out why this was happening as we had not seen this in the past. After giving up on the current setup we reformatted, installed Vista SP1 along with Company of Heroes, patched it up to the latest version and began testing again.

The results now recorded with the Radeon HD 4870 X2 looked much more realistic giving the Core 2 Quad processors a slightly advantage over their dual-core versions just as we saw in the other four games tested. We apologize for any inconveniences the original results may have caused and I am sorry it took so long to work out the problem.

When testing Company of Heroes with the Intel Core 2 Quad range we found quite a significant difference in performance depending on the processors clock frequency. As you can see the Q9650 running at its default frequency of 3.0GHz was 9% faster than the Q6600 at 2.4GHz which worked out to be 7fps.

A similar performance trend is found when testing the Core 2 Duo processors, though this time a 12.5% margin favors the E6850 3.0GHz processor over the E6600 running at 2.4GHz! It seems that once 3.0GHz is reached the Core 2 Duo processors hit somewhat of a limit at around 80fps.

Unfortunately the Phenom X4 processors scale quite poorly in Company of Heroes and even at the same clock speed the Core 2 Duo is superior. Despite being overclocked to 3GHz the Phenom X4 9950 was limited to 72fps matching that of the Core 2 Duo E6600.

Although the Phenom X4 processors were much faster than the Athlon64 X2 processors in Company of Heroes, the margins were not nearly as significant as those seen between the Core 2 Duo and Phenom X4 processors. The Athlon64 X2 6400+ was 40% faster than the 4000+, and from the 4800+ onwards we saw a 2fps jump every time the frequency was increased by 200MHz.
