RiVa AMMX Benchmarks

Thanks for the link I'd seen AMMX mentioned a number of times and had fair idea of what it was but I hadn't seen anything specific laid down and wasn't aware that it was compatible with MMX.

I don't think it's in any way compatible with Intel MMX.

It's just a poorly chosen name (because it creates confusion) for a useful set of instructions that they've added to the 68k ISA, because they can.

I wonder if they'll be able to make it fast enough, or whether eventually they'll add dedicated logic for decoding video.

That'll be difficult IMO (until they switch to an FPGA with DSP hard resource on it). But surely the movie is 24p, and this this enables 480p MPEG videos?

Not that anyone surely cares anymore about MPEG 1? Can this to MPEG 2? IIRC that used to take a reasonable bit of CPU grunt back in the early 2000s before hardware acceleration.
