For those who are confused because some "CISC" (Intel/AMD) processors are still more powerful than very good "RISC" (M1 or M2) processors, think of it this way:Jac459 wrote: Sun Jul 09, 2023 9:45 am For RISC vs CISC, it is the same. CISC is a less elegant architecture, they keep adding specific instruction sets in order to stay in the race...
To measure the efficiency of a process/product/anything, the method is always the same. You measure how many resources you spend and how much resources you get in return.
It is like a financial investment, you look how much money you block and how much "guaranteed" money you get in return, and you know the efficiency of your investment.
For CPU it is the same, you look at the TPD (the electric energy you put) and you see how much CPU (MIPS) you get. Generally an M2 is at least 2-3 times more efficient than an intel or AMD of the same generation.
You could also say that the resource we put on a CPU is not only electricity but also actual cost. But there also it is well known that a RISC CPU is much simpler and less expansive to build than a CISC one.
So whatever the criteria you get, RISC is much much better than CISC.
So basically, the reason why today the top CPU are still CISC (Intel/AMD) is just because it is not a segment Apple tried to go. If tomorrow AMD or Intel were to do the transition to RISC and try to go to the top segment, they would create immensely more powerful CPUs.
