CISC won over RISC? I think you meant that in reverse :)

- elai 17y agoJust look at the i86/x64 instruction sets + extensions. It's rather large.
- aaronblohowiak 17y agox86 is king. a terrible, ugly and far past its prime king, but king none-the-less. Edit: The replies below are insightful, I should not have been so reductionist.
- nzmsv 17y agoAnd beneath that CISC instruction set is a RISC core and a translation layer. The fact that the instruction set is CISC has more to do with backwards compatibility (hello, Windows) than an actual advantage of CISC.
- ssp 17y agoIt also has to do with CISC code being more compact. With memory getting slower and slower relative to the CPU, this is increasingly an (overlooked) advantage. Maybe at some point CPUs will do automatic code decompression in hardware.

- gloob 17y agoUntil you look at anything other than PCs. I'm reasonably sure there are more ARM chips in operation than x86, and ARM is (if I recollect correctly) a RISC processor.
