I thought bitcoin mining was floating point, and that was why GPUs were so adept.
- Dylan16807 7y agoMMX is obsolete. SSE/AVX has its own set of registers. It can do floating point and integer operations. It would not be correct to refer to it as a floating point unit. GPUs are good at mining because they can do so many calculations in parallel. They're just as capable of integer operations as the SIMD units on a CPU.
- wtallis 7y agoMMX was integer SIMD that re-used the FPU register file, but was not doing floating-point operations.
