I'm trying to quantify what percentage of Firefox users could actually use this proposal.
Using [1] and [2], here's what I got. Note: this is desktop only data.
For desktop we have ~97% x86/x86_64 usage between Intel/AMD. The remaining ~3% looks like apple silicon if I'm reading right for our only major AArch64 usage.
ARMv8-A NEON fp16 3% implied from Apple Silicon
F16C: No direct data. For Intel it was added in Ivy Bridge. The successor, Haswell, introduced AVX2. We have 82% support for AVX and 72% for AVX2, so I would guess F16C is somewhere between there?
AVX-512 fp16: Only in Xeon, so I'm assuming no usage.
@SPY (or anyone else) do you have any more accurate usage numbers here?
I'm going to see if I can find any mobile usage numbers, but that will take a longer time as our pre-generated dashboards don't see to track this.
