I think the battle between RISC and CISC is overshadowed by the battle between non-x86 and x86. On average are new designs more RISC than CISC? I don't know but that's different from numbers of chips of a certain type sold. RISC showed what you could do with a clean sheet and the battle has really been about whether we can afford the cost of changing to a new instruction set just because it's better by a bit.

>> by the battle between non-x86 and x86. 68000 -> PowerPC -> x86 -> arm Apple has been through 4 architectures in 30 years. Given enough money and tyranny (as in "were doing this" kind of leadership, vs committee) its apparently not that terrible.

  And rumors said, they even considered IBM RS-6000, but pushed to make simplified PowerPC, and IBM had not very good times, so agreed.

  Add the transition to "32-bit clean" on 68K (and some trouble with caches) + 32-to-64-bit transitions on PPC and x86.
