isn't that an interesting contradiction?

The numbers for SGEMM with NEON seem to be in the same ballpark as for a 4-core Intel CPU, while the numbers with AMX2 appear similar to the numbers for a 4-core Intel CPU with full AVX-512, or an 8-core AMD CPU. A desktop AMD CPU is much faster, obviously at a higher power consumption. I wonder if the numbers for DGEMM are only half of those for SGEMM, like in Intel/AMD, or they are worse than that (especially for AMX2).

It seems that recent versions already have good ARM optimizations, but they are probably still improving.

Even for AMD Zen 3 the optimizations keep improving, because I have tested my CPU with an older libgmp version giving a result of 7337, but a newer non-released yet libgmp version has reached 7816.
