@cmuratori@nothings Without SIMD: no diff for add/mul/sub, div/sqrt/transcendentals are 50%+ slower, 2x cache usage/mem BW. -
@rygorous@cmuratori@nothings I worked an animation studio that insisted on doubles. Main hit was BW and cache. - Show replies

@cmuratori@nothings With SIMD, you're also only half as wide as float SIMD. -

@cmuratori sounds like use floats. y u need all that precision on a phone/console? i bet ur gui is a million x slower than all your divides. -
@noojon I always do use floats, but for certain things that have numerical requirements, I have to make educated decisions... - Show replies
