    the 2 AGU / 2 ALU isn't genuine at all as the new units made Bulldozer wider than K8 was which was able to do only a total of 3 AGU / ALU operations at the same time; Bulldozer is cap able of doing a total of 4 agu/alu operations at the same time
    Yes one module is capable of 4 agu/alu ops, but that requiers 2 threads. For single thread your down to 2/2, but with a fornt-end thats much more capable then that of K8

    so all cores in the 150% faster statement by AMD have to run at only 90% of their peak single thread performance, which makes calculating single thread IPC even more complicated than ever before
    Your making a mistake, your talking about relative performance, which is not related to IPC at all or is only one part of the equation.
