    The only explanation is IMO that something is wrong/suboptimal when running only one thread.Which is weird since one thread should have all the L3 for itself.
    Moreover , one thread has both IMCs working for it.

    In the multithreaded scenario , data BW from both L3 and memory is shared => welcome to Amdahl's law.

    Hate to say it, but you're right......here's my Cinebench on Server 2k3 x64. Kyosen-san's single threaded score is unusually low....



    *BTW, K10 has only ONE IMC, not two
