Like I've said before, MAME runs well up to and including most 16 bit games on Tegra 3 devices (Nexus 7, Ouya, presumably the MS SurfaceRT if they sell any without having it returned). That's dual Cortex-A9 cores. This is the Tegra 4 with quad Cortex-A15 cores, which in terms of instruction efficiency is something like the jump from Pentium 4 to Core 2 Duo - double the perf at the same clock isn't unheard of.
