Shibumi, yes, cache hit % probably closer to 95 than 80.

Yes, but CPU companies have simulation programs that they have evolved over the years, purchased or in-house grown. These programs, especially if they have been tweaked to optimization for CPU architectures that have also been around for a few years, can be remarkably accurate in predicting performance. They take huge amount of variables data input and will do what-ifs all day, as you change the variables. I would feel quite comfortable about a new architectural feature, like RDRAM and its use in X86 computers, being a good thing, because it's being simulated by the company that invented it (the X86 computer).
