picCOLOR, CINEBENCH, WAV, DivX

CINEBENCH 2003's CPU benchmark, as you may have guessed, makes full use of the E.E 955's architecture, returning 811 marks for the overclocked model. The default-clocked '955 also manages to outbenchmark AMD's Athlon 64 X2 4800+, too.

We need an overclocked Presler to lay the smackdown on the X2 4800+ in the picCOLOR image-analysis benchmark, though.

Dual-core goodness is also evident in the recently released DivX 6.1 Codec. We've encoded a 416MB DV file into high-quality DivX video. The E.E. 840 was marginally faster than AMD's best, and the Presler 955 simply builds on that lead, encoding the file in 2m 46s.

A multi-threaded version of Lame also shows just how potent dual-core CPUs are when used efficient use is made of their resources.
