Apple Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

The only RISC that was ever part of x86 was so deep in the processor core and pipelines that no one programming the processor for general use ever noticed. It was only intensive applications where any special kind of optimisation made a lot of difference. The whole point of the x86/IA32 architecture was that it was meant to be backwardly compatible with the previous generations.

Again, RISC core + CISC userspace interface /= RISC processor
