The gaming benchmarks agree that K8 architecture suits well for games, and the Sempron 2600+ for Socket 754 outperforms the Sempron 2600+ for Socket A as well as the Celeron D 325 here.
The performance of the overclocked Sempron 2600+ is higher, of course, but the reduced L2 cache and the single-channel memory controller affect negatively its speed in games. That抯 why the Sempron 2600+ overclocked to 2.5GHz is slower than the Athlon 64 3500+ that works at only 2.2GHz in games.
The results of the WinRAR test which actively uses the memory subsystem are similar to what we抳e seen in games. The overclocked Sempron 2600+ is slower than both Athlon 64 3500+ and 3400+ here.
