I haven't looked at their newer offerings, but in years past that was definitely a problem that afflicted AMD -- having a fraction of the floating point execution units per core, creating AVX by adding an emulation layer over the existing SSE registers, etc. For a lot of use cases AMD could still be faster according to a wall clock (they weren't worse across the board -- those failings were used to purchase advantages in other chip features), but their peak flops were peanuts in comparison to the Intel offerings.
- jdsully 7y agoThat part is fixed. They even eliminated most of the downclocking issues with the AVX units on Intel. AMD has been pretty tactical with Zen2. The issues I’m talking about are execution resources for scalar code. Things like how many ALUs and which execution ports are able to execute which instructions.
