Crypto doesn't do floating point. Media transcoding does SIMD, but not usually not floating point.

Fair enough wrt media. However SIMD e.g. MMX is done in the floating point unit (https://softpixel.com/~cwright/programming/simd/mmx.php)

I thought bitcoin mining was floating point, and that was why GPUs were so adept.

MMX is obsolete.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.

MMX was integer SIMD that re-used the FPU register file, but was not doing floating-point operations.
