OK, I think I'll fire up a bloody discussion. Back in the old days, workstations were mostly RISC machines. Who doesn't remember the good old Alpha, MIPS, Sparc... And those beautiful SGI machines? And the predecessor to the MacPro (NeXT computer) was about to be a RISC machine too. NeXT Step would become OS X!! Personally I believe x86 should have been long gone now, as much as it's efficient and fast, but it's old tech and there should be an alternative (good one that is) already. MIPS seems to be making a comeback in the hands of Imagination, but not for this kind of application. Intel has (not for long it seems) the Itanium 9500 (Poulson) which seemed a great opportunity to kill off x86 but I guess higher values were more important. I believe only HP still uses these, and maybe not for long. The Chinese seem to be very active developing RISC processors, too bad the big players don't follow the lead on this one. Is anyone going to mention ARM? Still too far off. I guess we'll be stuck with x86 for a long time still. Any thoughts?
