Berkley RISC-I CPU outperformed every other single chip microprocessor in 1982. People talk about things that are good.
When a RISC CPU needs in avg 2 instruction to do the same work as the CISC CPU.
And the RISC CPU can execute 1 instruction per clock -
and the CISC CPU (like 68000) needs in average 8 clocks per instruction.
Then the RISC CPU is faster.. in avg by factor x4
This is your story of the 80th.
Now if the CISC CPU upgrades and does 4 instructions in a single cycle then the CISC CPU does the amount of work of 8 RISC instructions per cycle.
This means now the 68080 CISC CPU is many times faster then the RISC.
Very easy to understand.
