Scumbria: There is no inherent penalty to a long pipeline. If branch prediction is perfect, the pipeline length does not affect IPC, yet allows for much higher clock rates. Yes, but how was the branch prediction of the Cyrix chip? (didn't we just have this BPU discussion yesterday? ;)). There are other problems with a longer pipeline as well. Instruction throughputs are, ideally, not affected, but latencies are. In the real world, instruction throughputs would seem to be affected to some degree as well - at least if you want to keep the die-size down. -fyo
