With patch 1.2, Crysis has a very heavy CPU bench (to be found in the Bin32/Bin64 directory). The test was carried out at very high settings but at 800x600 so as to limit dependence on the graphics card. Affinity was forced on the physical processors, as Crysis is down by around 3% otherwise.
Penalised by their clocks and L2 cache size, the Athlon II X4s don’t really turn up in Crysis and are behind even the E6300. Indeed, they can’t even outdo the Athlon II X2 250, the gain given by the presence of 4 cores being completely undermined by their clocks and the lack of L2.
New to our test protocol, Arma 2 is configured with all settings at a max including max visibility (10 km), which brings the configurations to their knees. Resolution stays at 800x600 to avoid the graphics card impacting on performance. Note that you must disactivate HT or force the affinity for this game, as you’ll lose 15 to 20% of fps otherwise and it will suffer from rather disagreeable stuttering.
In Arma 2 things are different with the Athlon II X4s doing better than the Athlon II X2 250. Even better, the 620 is on a level with the Q9400 and the 630 on a par with the Q9550
