AMD Athlon "Thunderbird" 1 GHz / 800 MHz

Ever since the Athlon has been teamed with the KX133 chipset, it has been able to completely dominate most of the SPECViewperf benchmark suite. While Thunderbird is no exception, it actually comes out a bit slower than the original Athlon. One possible explanation is the immature nature of the KT133 platform. This is somewhat surprising considering the similarity of the KT133 to the KX133. The other possibility is that a larger L2 cache is more important than a fast L2 cache under these circumstances.

The results are the same here, but the Pentium III with RDRAM is finally able to edge out the Athlon 900.
