Video and Audio Encoding

Audio files encoding in Lame is a purely computational task. Therefore, among the processors with similar architecture the laurels are won by the CPUs working at higher clock frequency. Our results prove this point hundred percent.

The same picture can be observed when we encode video in MPEG-2 format. However, in this test the new Winchester core still manages to outperform the older NewCastle.

And when we perform MPEG-4 encoding with a DivX codec the older NewCastle ensures somewhat higher performance. Therefore, all CPUs based on 90nm core, namely Athlon 64 3500+ and Athlon 64 3000+ yield to their predecessors with the same performance rating. The new Socket 939 Athlon 64 3200+, however, outperforms the Socket 754 processor with the same rating.

In case of the XviD codec, the situation turns out completely different. Now the NewCastle core runs slower than Winchester. As a result, the performance of the new Athlon 64 3500+ is higher than that of its 130nm brother.
