IBM's Power PC 6 processor is apparently really something. Performance is such that I (for one) regret that it will not make it into desktop or workstation machines. I still think that RISC has a place in serious machines for desktop usage, but no manufacturer seems to think that way. Should one wish such a machine, she/he is stuck either co-opting a machine meant for server usage or attempting to build a special machine for themselves.
My dreams have been crushed!
