It is a fun way to benchmark your system. I managed to get 4.1hz on my 13th gen i5 work laptop.
Let's see an M-series chip blow that out of the water. ;)
EDIT - It was 4.1Hz in advance mode. Actually runs at between 22Hz and 44hz depending on each time I run it. Odd to have such a wide performance variation. I will just blame Windows and some power management setting/thermal throttling.

Shameless plug: I wrote a 'remix' a couple of years ago over a Christmas break using WASM+WebGL+DearImGui with better rendering performance, integrated assembler and a couple visualization tools (using the visual6502 team's original reverse engineered netlist data, and https://github.com/mist64/perfect6502 as simulation loop):
- 6502: https://floooh.github.io/visual6502remix/
- Z80: https://floooh.github.io/visualz80remix/
- 2A03 (this was contributed): https://floooh.github.io/visual2a03remix/
- source code: https://github.com/floooh/v6502r
(the simulation generally runs throttled to 1 half-clock-cycle per frame, so don't use it as any sort of benchmark)

I wish these guys would have released this amazing looking 6502 in circuits: https://www.evilmadscientist.com/2016/6502/

Well I've played the 6502 simulator as a kind on my 6502 Apple ][ clone :) :) :)
