Athlon 64: Video encoding
Encoding a video (duration 17m 12s) with different programs into different formats demonstrates a clear advantage for the Pentium 4 processors, with one exception. However, the P4´s advantage is slight (in the single-digit per cent range). Only with Ulead´s Video Studio 7 is the Athlon 64 FX-51 faster than the Intel processors. Obviously Ulead has not yet optimised its video application for the P4-architecture.
The TMPEG 2.52 test provides an interesting result for the Athlon 64 FX-51. This program permits the activation of special CPU features such as 3DNow, SSE, SSE2 and Hyperthreading. Although the Athlon 64 FX-51 also supports SSE2, it is slower in this mode of operation with this program than with SSE. The chip is fastest if all features up to SSE2 are activated.
