AMD's Bulldozer: More Design Details Surface

AMD's Bulldozer is one of the most highly-anticipated CPU architectures in recent memory. For those who are eager for more info on this new processor design, some new slides outlining Zambezi for the Socket AM3+ platform recently surfaced.

Breaking down the eight-core "Bulldozer" die, we find four modules that are each composed of two cores. Each module packs 2 MB L2 cache for a total of 8 MB. The is also an integrated Northbridge that contains 8 MB of L3 cache, two 72-bit DDR3 memory channels and four 16-bit receive/16-bit transmit HyperTransport links.

From the slides, we also see how Turbo Core will behave in Bulldozer. When the CPU's workload is within the TDP headroom, there is no core boost activity. When there is TDP headroom in given a workload, the Turbo Core kicks in and increases clock speed across the board. Conversely, when there is a lightly threaded workload, half the modules go into C6 sleep state, and the remaining cores get clocked up higher for better performance.

    This looks great and all but its going to supposedly be released on september 19th right? thats the new date given to us. Hopefully this wont be like their june, july, or august release dates or "end of 2010". Yup hopefully this is it. Hopefully it was a marketing decision so they could release it with there 7000 series gpu's. Then i can FINALLY upgrade

    Taht doesn't sound like a release date to me! We don't care. AMD stop trying to be Apple.
