I agree this is the issue.
This is basically a rerun of the argument a few years ago about whether Apple was *really* faster than Intel. Obsessing over minor benchmarking details and whether a particular comparison was "fair" or not missed the more important points:
- that Apple was providing competitive performance -- in a PHONE chip...
- that Apple was on a very different annual improvement trajectory than Intel.
We see the exact same thing here. This is Apple's *first* run at a desktop class GPU and already it's "competitive" with nVidia. Soon (end of this year? this time next year?) we'll be seeing M2's with the GPU that's the successor to the A15 GPU. And that A15 GPU was a substantial boost over the A14 GPU...
Most of these benchmarks are on code that was converted to Metal sometime in the past year and has not yet had the full optimization treatment applied. That, and Apple's annual trajectory, are the issue, not whether one can find a benchmark showing this curve goes higher than that curve.
