It will be interesting to see what these tests look like when Apple updates the Mac Pro with Apple Silicon. The rumors have the GPU having 2x and 4x more than the top end M1 Max SOC.
All I'll say is that it would be genuinely unprecedented if they could make that work. The M1 is impressive, but it's family of CPUs were a technical inevitability. ARM has notorious scaling issues, so I'm greatly interested to see if they bruteforce it or go a more tactical route.
The GPU designs in Apple chips has nothing to do with ARM, so even if we accepted that "ARM has notorious scaling issues" (a confusing claim, but even if we took the most generous route and assumed it meant "vendors using ARM have scaling issues" -- also not true) it is orthogonal.
What? The ISA is basically completely orthogonal to multicore scaling.
