MMX wasn’t actually that useful. The vectors were only 64 bits wide, you had no float support and the supported operations were kind of uneven... SSE and especially SSE2 were a much bigger leap.
- ido 2y agowhat gave the pentium mmx the big speed boost (I also remember it being quite significant) was probably the bigger 16kb cache (pentium classic had only 8kb) rather than mmx itself.
- Sesse__ 2y agoYup. More cache, higher clock speeds, slightly more flexible instruction pairing. Few applications used MMX anyway, I think.
- orthoxerox 2y agoI remember upgrading from Cyrix 5x86 to the aforementioned Pentium and suddenly being able to play Carmageddon. I've been thinking it was due to MMX for almost 30 years!
