Old single-threaded benchmarks demonstrate almost the same performance level for both; Athlon 64 X2 3600+ and 3800+: the performance difference doesn’t exceed 2%. Moreover, Athlon 64 X2 3600+ also performs quite well when overclocked: it outpaces Athlon 64 X2 5000+ working at the same clock frequency and featuring twice bigger L2 cache. Of course, it is fast memory that contributed mostly to this victory. Thanks to increased clock generator frequency, the memory is running at over 1GHz speed.
Although the size of cache memory doesn’t seriously affect 3DMark06 results, the situation between Athlon 64 X2 5000+ and Athlon 64 X2 3600+ overclocked to 2.6GHz changes to the opposite. As for the performance of our hero in the nominal mode, we have to admit that it is again much faster than the Intel competitor with the same price – Pentium D processor.
ScienceMark 2.0 is also almost completely indifferent to the size of L2 cache of the dual-core processors. So, the only remarkable thing worth mentioning is certainly the high performance of the K8 based processors.
