AMD Athlon "Thunderbird" 1.33GHz/1.30GHz

The “B” portion of the benchmark is actually quite easy to explain since 65% of this score comes from a Microsoft Media Encoder test which easily shows off the Pentium 4’s impressive memory bandwidth figures. 

This particular benchmark scales very well with CPU speed as the 1.33GHz Athlon is around 26% faster than the 1GHz Athlon.

In order to support our claims we took a look at the Encoding Performance numbers, and just as we had thought, the Pentium 4 definitely does come out ahead causing it to lead in the “B” section of the WebMark 2001 suite.
