I've been trying to decide whether to upgrade my PIII and if so what to replace it with. I ran some benchmark tests for comparison to other results at
http://benchmark.mameworld.net/header.htmlI've been using v102. In some previous testing, I found that anything above v102 results in a drastic slowdown on the PIII. I followed the guidelines at the site for MAME parameters. I just eliminated the ones that aren't supported anymore.
I tried to find ROMs that had been tested against most of the other processors and selected the ones that I thought were borderline and would give good comparisons against other processors. As a result, most of the ROMS I tested were challenging and the results tend to be lower than desired frame rates.
Hopefully this data will be useful to others. I have another machine that I plan to test (Core 2 Duo E6300) and will post those results when I get around to it.
