Acorn machines said it was pretty fast compared with a Z80 etc
The 6502 got its speed by restricting itself to 8-bit addressing in a lot
of places. E.g. the stack was limited to 256 bytes and had to be located
in memory page 1. The Z80, on the other hand, allowed for full 16-bit
addresses in a lot more places.
