AMD's Bulldozer: More Design Details Surface

By - Source: donanimhaber | B 62 comments

AMD has released new documents outlining the architecture for its upcoming Bulldozer release.

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.

See the full deck of slides at Computerbase.

    I hope this will be a worthy contender or surpases the current sandy bridges, otherwise we all are sure looking at higher CPU prices with the next intel refresh - both major cpu makers need to be competing or the prices will skyrocket and at the same time lower upgrades.

    We all remember intel back in the days before the Athlon came and started the competition that we today are enjoying.

    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

    Bulldozer has been Dukeing us for years. Hopefully it has a better outcome. Ivy Bridge has been delayed til next year, so if AMD has its act together, they could make some headway this holiday season.

    If these things are mediocre chips released in homeopathic doses, AMD is in trouble.

    acadia11Taht doesn't sound like a release date to me! We don't care. AMD stop trying to be Apple.


    acadia11, nothing can be like Apple.

    Looking forward to get one.

    I'm very excited to see an APU with 2-4 Bulldozer cores and 2-4 HD 7k cores.

    Does the Bulldozer include specialized circuitry for Turbo Core which will intelligently boost/shut down cores? Sandy Bridge had such mechanism, allowing it to take advantage of available TDP more efficiently and intelligently than the Phenom II X6, which just featured a reversed Cool and Quiet mechanism and probably doesn't really have a clue when to boost or shut down cores. It's also the reason why the Phenom II X6, according to reviews, doesn't spend too much time boosting its cores.

    This is almost nothing new, but at least it's better to see something about Bulldozer than nothing at all. Kudos to Tom's for that.

    Those current (ampere) boosts seem pretty intense, I wonder how much negative impact will that have on the thermals.

    I am eager to see how these perform. I need an excuse to make a new pc

    i wouldnt get a bulldozer till revision 2 anyway, just because there will be flaws.

    this is a low end enthusiast speaking, someone who will upgrade for power but not spend 1k+ on a cpu alone.

    even if the chip sucks, compared to intel, intel has nothing on amd gpu... a bulldozer with a gpu, and i mean a 68xx model or better could be the choice laptop of next years back to school, and make the chip a very viable option for more budget setups.

    this could be really nice, id love to see a decent 7xxx in it, that way it can crossfire, and make crossfire a viable low end option for people.

    Looks like this is going to be my first AMD system since the days of the Athlon XP 2600+.
    Just release it already!

    I came from a 955BE to a i7 2600. If performance per core is similar and multitasking performance at least 10-20% better I think I might switch back to AMD.

    One can dream though.

    It doesn't really matter what's written in this article. The thing is, without benchmarks we have no clue whether this thing will be able to catch or outperform Sandy Bridge or not. That's the ticket.

    killerclickThis will be slower and use more power than Sandy Bridge. In addition, the die is too big so AMD will have slim margins.


    Uau, you know so much! Thanks for the info, I'll just forget about it entirely and go buy Intel.
