Here are my numbers for the original M1 (not Pro or Max) soon after release: ARM Geekbench single core on M1 MacOS is 1734. ARM Geekbench single core on WinARM in VM on M1 is 1550. x86 single core on i9 MB Pro MacOS is 1138. x86 in emulation on M1 MacOS is 1254. Yes, 72% x86 Rosetta vs. M1 Native. However, x86 Rosetta on M1 was faster than the previous i9 2019 Macbook Pro x86 native. I consider that to be performant for running code that was compiled for a very different architecture.
