How would a 6502 with current technology be? (piefed.social)

The current CPUs use 3 or 5 nm transistors and run at MHzs and I was thinking how small and fast would be a 6502 or a Z80 with current tech?

Well, only 6.25 MHz... when the W65C02 can run up to 14 MHz and when CPUs stopped measuring the clock speed in MHz decades ago...

But it's a nice retrocomputer.
