Dan, <Two 64 bit cores couldn't be 50% faster than one 32 bit core? Why does that seem impossible?> First, 64-bit probably means that code and data structures will be bloated, so the fetch bandwidth may become a bottleneck. Bigger structures will have worse data proximity, which would lead to less cache hits, which will not alleviate the memory latency problem. Second, technologies for x86 code are already pretty much saturated and optimized. Not much can be squeezed out. Third, two computers do not do one job any faster. To effectively split a job between two processors, it requires global re-thinking of all underlying software-designing technologies, from better operating systems to new languages and compilers. Very few applications got to that level so far. Simple question of relevance: why we do not see any SPECfp benchmark results on dual P-III or quad Xeons? Regards, - Ali
