You can't just take the quotient of the processor clock frequencies and multiply by the number of threads! A current generation processor does a lot more in a single clock cycle than they did 30 years ago. Pipelines etc... didn't exist back then. The 6502 only had a single 8-bit general purpose register (although the index registers could also be used when not accessing memory).<p>An Intel Core i7 is probably more than a million times faster.
