It is slightly lower clocked, but the Phenom has 6 meg of L3 cache that the Athlon II doesn't. I thought MAME favored large CPU cache? Looking at the benchmarks over at Anandtech on paper, it looks like its a better performer, but I understand traditional benches don't always apply to emulation.

Note that the athlon II X2 used in the bench is 100Mhz faster than mine.
