AMD Athlon "Thunderbird" 1 GHz / 800 MHz

Under the Data Explorer test, the Pentium III needs RDRAM to edge out even an Athlon 600.

The same goes for the Lightscape test, but this time the Pentium III GHz with RDRAM is barely able to beat out the Athlon 700.

The results are the same under the ProCDRS test as well. Clearly AMD is doing something right in order to dominate these professional benchmarks as much as they are. It is nevertheless somewhat surprising that the Thunderbird falls behind the original Athlon. As noted previously, it maybe the immaturity of the KT133 boards used for testing or it may just be the larger cache of the original Athlon.
