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.
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.
