Back when I was upgrading my cab, I had a really old PIII in it, so I bought a cheap processor in the C2D familly with 512KB L2 cache. Concerned about the cache level, I tested it against my desktop computer's C2D with 2MB cache on the same motherboard, memory etc., both overclocked to the same speed. The result was few fps (as in ~4) in favor of the C2D with 2MB but I was never convinced it was due to cache, and attributed it to the fact that to get to the same speed, I had to overclock the 512KB processor more, since it had a lower clock.
I sincerely doubt very much you will get anything noticeable, due to the difference in L2 cache.
I also played with memory size and clock and dual vs. single channel and it was all completely irrelevant to MAME. My conclusion was clock speed and CPU architecture are the only things that really matter for MAME performance.
