    Will it have PCIe3?

    semiaccurate says that GF has problems with 28nm and amd will skip new generation bobcat :S

    17 min video for 2 slides (in case you're wondering the performance slide is at 10 minutes)?
    If that slide is real AMD can't even count the gflops on Llano... as the gpu is good for 480 gflops in the a8 on the desktop.
    In any case, seems to confirm earlier predictions. A solid increase but nothing earth-shattering (and gflops increasing more than performance - no matter the gpu arch this is almost certainly due to memory bandwidth not going up).

    But with Trinity you can get more memory bandwidth. IMC will officially support DDR3-2133, which should be enough to keep these extra FLOPS somewhat happy.

    Not nearly enough even if one creatively interprets Amdhal's opinion (yeah, perhaps not the best rule to take into account these days, but it holds merit!). They should get a better MC though (this is one of the areas where BD did improve siginifcantly vs K8L), which means reasonable increases on that front even without ludicrously priced DRAM (2133 is quite expensive when considered in the context of its slower clocked siblings).

    Actually I was wondering why AMD do not think of triple channel. I habour its gonna be useful.

    It's also expensive, and unrealistic for their targets (laptops, cheapie desktops etc.).

    It's none of that if the purpose is to make an APU that really discards a mid-high end discrete GPU.

    Unless you think adding a third memory channel is more expensive than an entire MXM card...

    But the bulk of the market remains integrated graphics. If you want a competitive product for this target, triple channel isn't realistic.

    Well, I suppose you could always design a 3-channel APU and let motherboard makers produce boards with only 2 channels for cost-sensitive markets. You'd need a bigger die and more complex socket, but maybe not significantly more expensive boards for OEMs that don't want them.

    Of course AMD wouldn't create a 3-channel solution for 500€ laptops..

    It's a matter of either creating a platform for that end or not.
    Yes, the socket would have to be more complex, but AMD coud sell APUs with 2 or 3 channels and motherboards with 2 or 3 channels, using the same sockets.

    A 28nm APU with dual-module Piledriver, Juniper-ish iGPU and efficient 3-channel memory controller would nail all the 800-1200€ laptop designs that are today ruled by Sandybridge + nVidia GF108/GF106 combos.

    Ivy Bridge GT1 @ Coolaler:
    http://www.coolaler.com/showthread.php?t=278192&page=11

    HD2500 15.26.0.2500
    900 Mhz Vantage GPU: 1150
    1500 Mhz OC Vantage GPU: 2022
    900 Mhz? 3DM11: P351 (263 graphics-score) compare

    Circle @ D3D-AF-Tester:
    [​IMG]

    So HD 4000 might go against HD 6450?
    16 EUs @ 1300MHz (Mobile-i7) should deliver ~330GFLOPs(@MAC)?

    Nice circle there. :)

    For mobile, even the dual core should have HD4000.

    Does anybody see more than 6 SIMD engines (384 SPs) in that die shot of Trinity?

    No, I don't. I think AMD promised a 50% increase in FLOPS, so that's strange. Do they intend to push clocks 56% higher than in Llano?

    Well, come to think of it, that would only be about 940MHz, which sounds doable, at least in Turbo mode. Still a bit odd.

    You're right, Llano indicates ~600 GFLOPS, Trinity indicates ~1100 GFLOPS, making the difference ~78% according to that chat. Obviously there's room for interpretation based on how thick the line is and where the labels are placed, but that's how I see it anyway.
