Thanks for posting this, been interested to know how Zen5 would perform running MAME for a while.
Do you know what cores MAME was running on?
Be interesting to compare the performance on 3D V-Cache cores vs the slightly higher clocked cores without the extra cache, by confining MAME to only running on CCD0 and then on CCD1 to see if MAME is affected more by the extra Cache or more clock speed or if doesn't matter.
