Using SIMD instructions (MMX/SSE/AVX) ○ Most operators limited to floats but recently more general purpose (integer) vector operations have been supported ○ Registers keep increasing in size -- the next generation of CPUs will have 512 byte registers which may be sufficient Nobody uses MMX these days, SSE and AVX are not mostly limited to floating point, and AVX-512 is 512 bits, not bytes.
