    so i think the numbers do make sense (when thinking about peak power draw for different chips) and we have seen amd offer really fast lower clocked cpus, but i dont think they would want to hurt their higher chips sales by making the cheaper ones win in some/alot of benchmarks.
    The L3 cache is 8MB for all chips, so no additional power needed for that. I'm starting to think it's a process restriction (over 4.2 GHz, GloFo's 32nm might consume too much power or require high voltages, both situations affecting the chips TDP) but we will know that when we can actually overclock them. Can't wait to get an eight core in my grubby mits!

    As quoted by LowRun......"So, we are one week past AMD's worst case scenario for BD's availability but they don't feel like communicating about the delay, I suppose AMD must be removed from the reliable sources list for AMD's products launch dates"
