Mini-GZIP	Source: zlib

The Mini-GZIP benchmark contains both 64-bit benchmark that measures the performance of an AMD64 optimized version of ZLIB. It also contains a 32-bit benchmark implemented with the standard (unmodified) ZLIB. Lower is better.

AMD Sempron 3600+ (WinXP 64/32 Bit)	9.38
AMD Sempron 3600+ (WinXP 64/64 Bit)	4.57

We see the same trend here in Mini-GZIP as we do in ScienceMark, when running the 32 bit software, Sempron 3600+ trails the other processors by a fair margin. Moving the OS and software to native 64-bit mode really boosts performance.

DiVX Encoding	Source: PCStats

The DivX encoder benchmark contains both a 32-bit and a 64-bit benchmark that measures the performance of raw video encoding of the AMD optimized DivX video encoder version 503. The encoder has been optimized for AMD Athlon 64 and AMD Athlon 64 FX systems (both 32-bit and 64-bit). Lower is better.

DiVX encoding requires a lot of computing power and the AMD Sempron 3600+'s L2 cache disadvantage shows itself here. Compared to the more expensive Intel processors though, the Sempron 3600+ isn't completely out of scale.
