And yet we still see people comparing very small code snippets. This pisses me off.

This is true, but what to expect ? 6502 is designed to work on a setup where memory is faster than the cpu, and not the 68000. I'm no hardware designer, but isn't it obvious memory performance get worse as clock rate gets higher ?

Compare that to todays architectures experiencing a cache miss, and you'll see who's bad in terms of ram performance
