It is hilarious that the SPEC2026 graph does not include apple's P-cores. And no, not because they are ARM and not x86, since Graviton is included. It is because their integer & FP scores of 9.8 & 13 respectively absolutely wipe out everything else on this chart.

The single-threaded results of the Apple cores are excellent, but the multi-threaded results per socket of a Zen 6 absolutely wipe out any Apple CPU.

The Apple CPUs may be great for a personal computer, but they are not competitive with a server CPU.

Moreover, the SPEC floating-point results are not really representative for the floating-point performance of Zen 5 and Zen 6 that can be reached with optimized AVX-512 programs, which is much greater.

I mean, this is a review of the server grade parts. Apple is not exactly selling m chips to hyperscalers right?

Different story when you're talking about the context of a desktop or mobile.
