[citation][nom]JasonAkkerman[/nom]What are you smoking? That's what Apple said 25 years ago and we see how well that worked out for them. x86/x64... resistance is futile.[/citation]
25 years Apple was using the 68K line, a CISC processor family, and the 6502, which was also a CISC processor. The first RISC based machine, the RT PC wasn't quite out yet.
So, sorry, you're wrong. x86 processors aren'tt true CISC anymore, anyway. It's a kludge that changes x86 instructions into RISC instructions that are then executed.
There's absolutely no way Intel would choose this now for a new instruction set. The front-end of the decoupled architecture is a necessity for compatibility. So, RISC did win. So much so, even instruction sets not designed for it, found a way to use it for their processors.
CISC was a good idea when memory was very expensive and small. But, when memory capacities grew, the advantages of RISC outweighed the benefits of greater code density, by a lot.
VLIW, on the other hand ...
