Western Design Center offers the W65C02 which can run at more than 14 MHz since the early 1990s so a 20 MHz 6502 is not so impressive in itself.
What’s impressive is they got it running on a VIC-20 and the fact it’s made of discreet 74 series logic ICs.

He also had it working on one of my PET machines at World of Commodore 2018. Incredible!
