After adding a bunch of historical benchmarks to the page I figured I'd do a run on the nightly builds in the old style (pre -bench) of actually outputting video and sound.
So these are what you can expect from games running full tilt with video and sound and default mame.ini settings for 90 seconds:
mame gamename -str 90 -nothrottle -norc
It's kind of interesting.
I also added a .229 run from my venerable 2008 Core 2 Duo e8400 Wolfdale.
