DB, "I made a short list of IPC improvements" The list you compiled looks very impressive indeed. Unfortunately, I don't see much in it that would address optimisation of outside memory traffic, the area where AMD is currently quite behind Intel. From what I am gathering, current AMD Opterons are about equal in terms of _raw_ IPC performance to Core 2. The performance lag is in handling of external memory traffic, the issue that was always overlooked historically, misunderstood and under-appreciated. Until AMD manages to manufacture caches as big as Intel does (and same low latency), no nitpicking in _raw_IPC_ would regain performance parity, IMO. Sorry, - Ali
