"It strikes me as bizarre how little we know about Apple CPUs even after two years. The basic numbers (logical registers, window, ROB size) seem to about match Intel these days, and the architecture seems to be 6-wide with two functional clusters. There appears to be a loop buffer (but how large?) But that's about it. How well does the branch prediction work and where does it fail? What prefetchers are provided? (at I1, D1, L2. L3) Do the caches do anything smart (like dead block prediction) for either performance or power? Does the memory manager do anything smart (like virtual write queue in the L3)? etc etc etc"
