You can notice the influence of the L2 cache size on the performance in the tasks of the kind only during data compression in archiving utilities we used. In all other cases Athlon 64 3200+ and Athlon 64 3000+ perform very close to one another: the performance difference lies within 1%.
As for the general performance of Athlon 64 3000+ in this type of tasks, it is pretty high during data archiving and MPEG2 data encoding. As for all other applications, such as MP3 encoding, WME and MPEG4 data encoding, and the like, Pentium 4 processors have always been much faster there. Even overclocking Athlon 64 3000+ up to 2.2GHz won’t help, as well as the use of the dual-channel memory controller in Athlon 64 FX-51.
