    In its latest presentation to industry partners, AMD detailed its upcoming Deccan low-power computing platform, targeting the market Intel's Atom and VIA's Nano processors do. AMD is currently behind the "Zacate" and "Ontario" processors, which deliver high performance/watt x86 computing at low power draw and costs. The company's future platform will be called "Deccan," consisting of processors codenamed "Wichita" and "Krishna," targeting the ULV desktop and netbook markets, respectively. With the next generation, AMD is looking to take advantage of the 28 nanometer manufacturing process to put four x86-64 cores based on the Bobcat architecture on a single piece of silicon, with an integrated memory controller and AMD Radeon discrete-class graphics.

    The biggest change here isn't the fact that there are four cores, or that it's built on 28 nm, but that Wichita and Krishna are completely single-chip. The FCH or Fusion Controller Hub has been completely fused into the APU silicon. Motherboards and notebook logic boards will have just one big chip, with no "chipset" of any form. This makes AMD's Wichita and Krishna the industry's very first true x86-based consumer SoC (system on chip). The integrated memory controller now supports DDR3-1600 MHz memory. The integrated AMD Radeon graphics is set to get a performance and SIMD boost, as well, including a Secure Asset Management Unit (SAMU). AMD's next generation APUs are slated for 2012.

    Too bad there's no more specificity other than the year 2012. Looking forward to see how these perform against Sandy Bridge ULV's. My girlfriend could use a lighter ULV notebook in the near future.

    Something to note is that even though the Deccan chip is 20w, it's still 2w less than the 18w Brazos because the Brazos needs a 4w FCH(an overgrown Southbridge)

    Man I'd really like something like this in a new Macbook...*hint* *hint*...Steve...I want graphics, not craphics!! I don't need i7s in a budget machine!! But I do want to have a decent GPU.

    Course, they've already lost my business outside of the used market. So, my opinion doesn't matter. That and I don't think Steve understands the meaning of the word "budget".

    If only the integrated FCH of these chips also featured at least 4-channels of ONFI, these would have made the perfect x86-based SoC.

    First and last image looks fake...look at the AMD logo in the bottom right corner

    AMD is bad at Powerpoint, you can expect such errors.

    Are these only for notebook/netbook platforms, or will they be available for desktops aswell?

    I think the "Krishna" refers to Krishna river/district.
    de.das.dude says thanks.

    Intel's answer?

    I was planning on building an e350 based htpc in the near future, but hearing about these made me wonder if I should wait. But "sometime in 2012" might just be alittle too far off. The real question though is, what will Intel's answer to this be? Sandy/Ivy Bridge based Atoms? I just wonder how much longer Intel can keep it's market share in this segment without greatly improving its video capabilities. I am impressed with what AMD is rolling out lately, but they really need to make more of an effort in marketing. If more computer illiterates or "non enthusiast" buyers knew about AMD and APUs, they would gain a lot more market share. Most people I talk to about them didn't even know they existed.

    Intel's answer is scaled down Atoms. Sandy and Ivy ULV processors could be 10 times as fast but they also cost an arm and a leg compared to Atom/Brazos

    Thats the sad part of AMD, never good at marketing!

    Sounds very promising.
    So if they can fuse all this together then AMD should be able to make some serious cpu's in the near future for Desktops ?
    Maybe a fused 24core desktop cpu eventually that is already 5 years late.

    I can see a few of these APU's in a server farm / data centre, space, size, heat, power ....

    NC37 APU in a macbook air sure, not in a ?? pro or whatever it is called now, not with the 2nd Gen I7 mobile cpu's they have now.
    As for craphics "Apple Achilles heal" there is no chance in hell that it would improve.

    I have been asking since PB G4 ATI1600 the last Apple laptop that was build.
    Remember the Apple joke " my mobile phone has a better graphics card than the PB pro"

    I love my Zacate based netbook. Playing those indie steam games or watching HD flicks in the airport. No doubt Krishna will be another winner.

    Well yes, of course they will scale them down, but do they have a quad core atom in the works? Let alone a quad core atom that can compete with the GPU capabilities of these new APUs? Even when paired with an Ion chip, the best current atom gets beat by the E-350. Intel needs to increase both cpu and gpu performance of their atoms chips in order to produce some real competition for these new APUs.

    i couldn't help but think of the movie Zombie Land when I read the name Wichita...

    so i guess they'll tell us how many gpu cores later?

    There are already ATX FM1 mobos, so yeah they are for desktops and HTPCs as well. You can even add a second HD 6450 video card in their PCI-E slot and get very decent 3D perf.

    My 2c: after the 32nm factories are depreciated in 1 or 2 years, Intel will start selling cheap sandy bridge ULVs en-mass and continue to scale down atom it hits the <1W mark.

    Problem is Atom doesn't scale so well once you increase the power package(it lacks out-of-order execution and has a very long pipe-line kinda like P4), so increasing frequency and TDP to compete with Brazos doesn't make sence. So Intel will leave the >8W space for ULVs and the <8W space for Atoms. At least this is what happened with the core solos and core duos before Atom was released...I don't think anyone can answer your question for certain. So my guess is as good as anybody's right now :p
