Windows Media Encoder 9
Microsoft Windows Media Encoder 9

Notes
We see some pretty amazing results in Media Encoder 9 with the Athlon 64 X2 4800+ running at an aggressive 2.4 GHz and complemented by aggressively tuned DDR400 memory. Not only does the chip simply trounce every single-core offering from AMD (including the 2.6 GHz Opteron 252, but it also blows right past Intel’s dual-core Extreme Edition 840. It even cruises on by the Opteron 875, a dual-core chip running 200 MHz slower. The 4800+ very nearly halves the encoding time of AMD’s FX-55.
