If no better code exists that's the performance.

It exists. E.g. on macOS it’d actually use the AMX matrix multiplication units (for benchmarks that use BLAS) and blow away most x86_64 CPUs that have to rely on AVX2.

Fair, but phoronix is a linux site, and thus performance under macOS won't be of interest for most readers. The performance as stated is the actual performance one currently gets under linux, regardless of potential.

Which is deeply interesting to people who want to run Asahi Linux on an M2.

I found the data compelling--M2 silicon under Linux is generally competitive against contemporary strong x86 laptops, but if you are sensitive about the performance of a particular workload, choose your device carefully.

I’d say Phoronix’d audience prefers Linux but are quite friendly to other Unixes. The Mac has a very reasonable Unix running on it.

Fun to think that Apple almost has a monopoly on RISC technical workstations…

If it is not emitted by compiler running on a linux distribution targeted to run on M-Family Macs, it does not exist under Linux.

That’s technically true, but it’s also a bit like saying if there’s no fuel, a car is paperweight.

It is practically true! Beware of "Bionic Duckweed" and pricing in apparent future (thus yet nonexistent) tech (or software).

With every benchmark there is an objection, because every benchmarks measures a specific thing, and that specific thing is not the thing everyone wants to see measured.

These benchmarks tell you what performance you get with this array of programs, on linux, with these machines. You want to know something about the inherent performance capabilties of each cpu, which is very hard to figure out, since we will never know when/if any of these programs has had a totally optimal solution for each piece of hardware.

Usually the best you can do is just measure actual programs people use.

Wasn't this precisely the chicken/egg problem electric cars had to solve to start getting the adoption they're seeing now?
