    LOL, thats kind of how i feel after getting this phenom rig, but if 45nm is really as good as they say it is then i guess it was worth it.

    Yes correct, the real vcore is around 1.3V afaik.

    It's aliiive! IT'S ALIVEE!!!
    Starts looking good for AMD
    This is much better demo than 65nm k10 ehh? (taskmanager anyone?)

    well... EUV is due to 2016 so we're gonna mess around with 32 nm structures for quite a while. the only thing that will matter then will be the architecture.
    Notice any grammar or spelling mistakes? Feel free to correct me! Thanks

    Also look at the latest post made by wombat containing pictures of 16 cores machine utilizing Shanghais,now with VCore readings @1.15V.

    dude just want to use opportunity and say congrats for amazing little util that become must for Intel and AMD in showing their new products!

    Please, do not confuse vCore with Core VID

    All we need to know is clockspeed. 16x 1.8/2.0ghz is not going to be as good as 8x 4.0 GHz of the Skulltrail (and its associated server equivalents) due to communications latency and overhead.

    Please correct me if I'm wrong.

    @spicypixel: These are C0-Stepping CPUs, they wont go retail before C1/2, so the clk-speeds theyre running now has nothing to say about the real clk-speeds when launching.

    Nothing but pure speculation on my part, but I'd wager those cores are running in the range of 1.8 to 2.2 ghz.
    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"

    That's fair enough. Shame its so many months away, can't even get a decent Quad Opteron system at the moment so seems my render farm is nearly a year away

    Well well, much a go as usual wherever AMD gets mentioned since Core 2. Hopefully less abnormality this billionth time.

    2.8/3.0G was mentioned as the speed for the higher clocked models, if and hopefully, they believe. Don't make too much about it yet until you see something, same as with Nehalem. Wild guesswork on no info or experience really only shows ones character rather than fact.

    Jack: AMD were supposed to ship 45nm samples to select customers for validation and testing around mid-April AFAIK but the B3 around 20th March. Both the B3 bug free Barcelona and the C0 Shanghai/Deneb samples were up and working well in stress testing Jan. 15th and being produced in the 300mm SOI wafer Fab 38 and Fab 36. Fab 36 has some testing toolsets for 45nm CPUs since November '07 AFAIK. However, on both fronts they were ahead of schedule and so shipped the validation samples of B3 Opteron beginning March along with some 45nm Shanghai/Deneb samples. The link you posted mainly dwelt on that as in here and better explained over here.

    If VID is 1.150, VCore is one step higher, i.e. 1.160-1.200 depending on the CPU MSR coding. It could easily be in power saving mode, that's usually the VID/VCore for it.

    This is almost the best news for AMD since their AMD 64 releases.

    Meh, I won't hold my breath.

The universe will go on, indifferent to our brief existence, but while we are here we touch not just part of that vastness, but also the lives around us. Life is the gift each of us has been given. Each life is our own and no one else's. It is precious beyond all counting. It is the greatest value we have. Cherish it for what it truly is."

    by no means don't...

    It's funny to se that some people just can't come to peace with the fact that AMD isn't gone of with the ways of dodo and is in fact in preparation of big come back...

    I dunno no...

    Intel using high-K gates. AMD using SOI and immersion... and probably high-K gate in later revision.

    But things are getting pretty small and crowded... when AMD was shiping 130nm K8, and building new fab to make 90nm, it was difficult to image 45nm, but here we are. How will they make 32nm or 25nm... shifting masks and immersion only go so far.
