zlib Mini-GZIP 1.2.3	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.

The Intel Core 2 Duo E6600 does well in this compression test and is able to squeak into the lead although all systems perform well in this 64 bit compression benchmark.

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.
