    Source from XbitLabs


    So these are the specs so far:

    - 32nm SOI (probably on GlobalFoundries);
    - 4 x86 cores like the Propus in Athlon II X4;
    - 6 SIMD units of 80 stream processors each = 480 SPUs;
    - No L3 cache, 512KB L2 for each x86 core totalling 2MB L2 cache;
    - DDR3 1600MHz controller;



    No word on the amount of memory channels, but If price point is an issue, I'd say it will be 2 as usual, or 3 as maximum.



    There's also no word on clocks, or on either the stream processors will have a different clock from the CPU.
    If the GPU components operate at the same clock as the x86 cores, we're probably looking at 480sp @ ~3GHz (don't forget this is 2011, and 3GHz should be standard even for mid-ends).
    So this first fusion CPU could have the same graphics processing power as nowadays' HD5850, which is kinda scary to imagine for a single CPU+GPU chip (of course, with a 128bit DDR3 controller it would drown in bandwidth limits, I guess. But AMD still has that Sideport technology to take advantage of).

    But even if the GPU part comes at the vanilla 500 to 700MHz, it will still be 10 times faster than today's typical IGP performance, which is also very good nonetheless.

    8 hours later and it has 40 views and no replys?

    wow.. this news is that uninteresting to the TPU folks?

    I'm disapointed.

    nice to see some specs from AMD here. I want to see some benchmarks of this and more specs. 480SP@3ghz would be sick but i think they are going to have different speeds. I could also see that being a problem for overclocking as you would have the 4cores+GPU to overclock and they all aren't going to reach the same limit..Thanks for the post

    Thats great .. so i guess the gpu will be better thana 3870?

    if the shaders are clocked higher then the 3870 then i don't see how it wouldn't be if it has the ram bandwidth


    EDIT:I forgot that the 3870 has 320 shaders so yes it should be faster if it has decent clocks

    It'd have edicated ram on teh mobo or shared ram ram

    i say, it will use shared ram in mobo (or maybe AMD will use sideport memory)

    i realy hope AMD can push the deadline, 2011 is so loong to wait

    I hope it uses some fast Sideport ram and have option for Sideport+shared that would be great if it did.

    Well we mainly just absorb the info. There is nothing really to say. It looks great on paper, but most people here are a "I want to see real life test numbers" kinda guys. Hell, I just read a news article that was "attack" for having the gale to be just news.

    On a side note: This looks really great for laptops, but will never have a place in the desktop world (not for use enthusiast at least).

    I think it would have a use for light gamers and workstation rigs(not high powered ones but things like CAD and photoshop/photo editing IMHO it should be great for that)

    i can see this being great in prebuilts

    If the CPU + GPU are a single die and there is enough room left on the substrate, how about:

    I drew this up in MS Paint. :D

    Well it allows two things. As a combined chip, it should use less power because their is no longer a need for a bus link between them. GPU to CPU communication will take less power. It also, even if the chip has to be bigger, will need less over all space because those bus lanes, spot for second chip, capacitors, power connections, etc. all get cut down. And by the time this is ready, Sideport GDDR3 and GDDR5 memory modules should be smaller. If I am not mistaken the Northbridge in an AMD setup sole job was graphic communications, so merge it with Southbridge (-1 more chip).

    So for laptops we get:

    *Gaming laptops with less parts, so they can be made smaller
    *Better cooling as there is now only 1 major source of heat
    *Cheaper to make due to fewer license requirements, and lest parts
    *Netbooks can be made either smaller, or given more power without increasing size
    *Less power, better battery life due to fewer components to provide power to.

    Desktops we get:
    *Dell, HP, Acer, etc. make cheaper, smaller desktops
    *Better power efficiency for pre-builts
    *Less complex Mobo decreases possible break down issues
    *More complicated upgrade paths

    You know what would be a cool feature, AMD-V for the GPU as well. You could fold on 5 of the 6 SIMD and leave one dedicated to desktop graphics. You could then easily do everything, but game with no noticeable graphics lag. And the obvious instruction set to delegate parallel processes to the GPU core when need to drastically improve performance for certain task with no need for specially programmed software. You could encode a DVD in less than 12 minutes for a 2 hour movie and still browse the next while you do it.
