RISC *is* the future of computing. It's just a lot more convenient if the RISC processors are hidden behind an x86 instruction decoder![]()
AFAIK, all x86 cpus since the pentium pro have internal RISC units or something like that. The PS1 and Sega Saturn both had RISC cpus, so you know RISC has to be a good thing
Maybe in another 14 years (in kernel 2.6.397) they will fix some of today's bugs on x86. Of course by then no one will use x86 cpus anyway.
A lot of the Alpha designers ended up going to AMD and helped design the original K8 (Athlon 64), if my memory serves correctly. Some very smart guys.
Dirk Meyer, the current CEO of AMD, was actually the co-architect of the EV4 and EV6 Alpha processors.
Before DEC/Compaq started its downward spiral, there were plans for a single motherboard/chipset to be able to support both Alpha and AMD CPUs. Remember Slot-A Athlons? Well, there were Slot-B Alphas, and Alpha motherboards using AMD chipsets.
Too bad they never got to the stage of producing motherboards that could actually swap CPU architectures.

There are lots of other cool AMD-Alpha related things that I'll let you discover on your own.
Probably there's just one way in for the instructions to the processor, so they have to go through the x86 decoder and as such must be in CISC form. I'm no expert, but I think RISC and CISC refer to the design of the chip and how it does things, so you can't really convert a CISC cpu into a RISC one just by toggling an option in the bios. If you want Linux on a RISC cpu get yourself an Alpha, or something more pratical like anything with an ARM cpu in it or a pre-intel Macintosh (PowerPC only, motorola 68K is CISC). The Wii, XBOX360 and PS2/3 all use RISC cpus as well and I think you can run Linux on those.
