    I thought the turbo is working on each core even in full load, isn't it?

    Let's say 2.5Ghz(3.2Ghz turbo) Trinity offers the same performance as A8-3850(2.9Ghz) then I would be totally surprised.
    Honestly, I don't think that will happen, because Trinity without L3 would need ~10-15% better IPC than Llano to perform like that and the best ES 3.8Ghz version would perform like 4.2-4.4Ghz Llano, I think that's too good to be true when BD+L3 IPC is at least ~5-10% worse than Llano.
    Yes it's surprise because Trinity is 2M4C and would have disavantages comparing to true quad core.
    There was a leak which said A1 Trinity is on par with a8-3850 in Cinebench, but the frequency is still in doubt. Even if it's the top ES then Trinity must have much higher per-thread performance. According to this chart(http://www.hardware.fr/articles/842-...s-3-2-ghz.html), 2M4C has 25% disavantages compare to deneb, it may imply ES trinity's ipc is nearly the same or less than Llano because frequency different is about 30%.

    EDIT: I found people is not that interested in trinity, right? It's sad there were too much arguement about zambezi but no more about trinity even right now.
