That picture of Llano die is actually not complete ,look up a few posts.
The not-cropped picture shows much greater section dedicated to GPU,approx. ~480SP.Total die size est. 200+mm2,est. IMC is 192b wide supporting 1600Mz DDR3 memory.

quad core +
4750-4770(ish) gpu
and only ~200mm2, sounds pretty damn sweet

wonder what kind of clocks it can reach? and how much power it will take. im thinking it could do 3ghz core for about 50W and 900mhz on the gpu could be under 50W aswell. would be a killer package for nettop pcs

The APU will succeed for these reasons:
1) Software support already exists and is supported by major software vendors; Microsoft's DirectCompute and Khronos Group's OpenCL.
2) Not only AMD, but Intel are making APU products.
3) AVX works on AMD and Intel

AMD will simply be in an amazing position with their future products. Also new AMD APUs will come out yearly, instead of every 4 years (CPU) or 6 to 12 months (GPU) thanks to the type of design AMD will be using. The AMD haters will be silenced in 2011.

Thankx for the picture :^)

It was clear that it was cropped from the DRAM IO paths, so I had
already extended that. Also the other (left) side shows a truncated
HT IO module (It seems there are four half HT units)

I had expected a 64 bit GDDR5 "side buffer" below the GPU. I wouldn't
know where they would otherwise get the memory bandwidth from...

The IMC width is 128 bit . It's exactly like the regor one. Maybe it
runs faster but it seems more logical to have a side bus with a minimum
of two GDDR5 chips with could fit in the package itself providing much
more bandwidth as the standard IMC.

The foils say it has an high frequency memory interface in a such a
way that it strongly suggest that it's GDDR5 compatible.

They are saying its 480.

Oh nice. The new OpenMM (OpenCL enabled) Folding@Home client will LOVE Llano! I wonder how the GPU cores will work with a discrete GPU installed too. Some form of Crossfire? Or better yet, have a Lucid Hydra managing the load balancing between the two .

Either way, maybe we can expect some good PPD in 2011.

i was thinking they should offload bullet physics to it

[hurleybird]

I don't think lucid hydra can interface with a GPU integrated to the NB or CPU. Hydra is meant to be to be placed between the pcie slots and the pcie controller, and is designed accordingly. Moving the GPU to the wrong side of the system probably breaks compatibility with hydra.

I can't make sense out of this, so has anyone seen some info floating around
the net on this "news", if it is and not some kind of fake.

2010 H1 would be too early but I can imagine a 2010 Q4 date for it. The offical date is ~2011 but nowadays the AMD likes to repeat the "ahead of schedule" sentence in its presentations.

Maybe he was thinking the year is Jan 2010 and meant that the product will come in q1 2011 ... lol

Or maybe his Chinese is messed up "if he gave the speech in Chinese"
Or maybe its true APC in 2010, but who am i kidding i want the bulldozer

2010 H1 would be too early but I can imagine a 2010 Q4 date for it. The offical date is ~2011 but nowadays the AMD likes to repeat the "ahead of schedule" sentence in its presentations.

But almost a year ahead

Wow, well done indeed....

The tape out has done (theoretically), and the 32nm technology will be ready for production in 2010 H2. So we will see what happen.

And Anand is saying AMD is saying it will be GigaFLOP APU

In other words HD4850 ALU performance .

yeah AMD said that, but gigaflop performance doesn't mean HD4850 ALU performance, it would have at least a HD4850 performance if they said "it will be a Teraflop APU"

[Helmore]

yeah AMD said that, but gigaflop performance doesn't mean HD4850 ALU performance, it would have at least a HD4850 performance if they said "it will be a Teraflop APU"

Current rumors say that it will have the same amount of crunching power (per clock) as a Radeon 46X0, although it will be based on the 5000 series architecture and it basically is a 56X0 with 320 SPs. Also note that I didn't say performance, but crunching power. I've no idea what kind of performance to expect. This is all just rumor so far anyway.

[Lightman]

yeah AMD said that, but gigaflop performance doesn't mean HD4850 ALU performance, it would have at least a HD4850 performance if they said "it will be a Teraflop APU"

Yeah, I know... I've made late night mistake

Anyway as Helmore says it should be HD46xx crunching power with HD5xxx or even 6xxx capabilities in that regard.

Man, just stop and think about that!


If within two years we can buy a single CPU + Motherboards and have a complete system, that delivers incredible gaming performance TO ALL, for relatively cheap. Then this platform will take the industry by storm.

AMD Fusion 2nd gen... think dx11 system, AMD Black 955 performance + ATI Radeon HD5750 graphics by 2011? Or even close to that will be impressive. Who'd buy anything else? (relatively speaking, of coarse!)

Stuff that into a small box and Microsoft has the new 360!

[Nedjo]

yeah AMD said that, but gigaflop performance doesn't mean HD4850 ALU performance, it would have at least a HD4850 performance if they said "it will be a Teraflop APU"

all AMD needs for 1TFLOP is 400 Stream Processors@1250MHz... and that's absolutely achievable! My guestimation would be 1300 MHz 'cos of appropriate multiplier - 6.5x for APU, 10.5x for NB, and let's say 15.5x for cores and yeah Q4 2010 is in line with GloFo roadmap... but Computex 2010 demo does sound plausible... remember that first DX11 accelerator (and Ll(el)iano) will be DX11 APU was demoed at Computex!

4770/4850/57x0 cards had mem bandwidth about 64Gb/s, 4670 had twice less.

How they gonna provide at least 32Gb/s to their IGP ?

umm dual channel DDR3 + on chip cache...

[Oliverda]

umm dual channel DDR3 + on chip cache...

...or two 32bit GDDR5 chip close to the socket. Freq and size can depend on the mobo manufacturer.

[Smartidiot89]

Well this is from AMDs Analysts Day 2009...

Journalist: Rick you mentioned that you will be sampling Bulldozer and Bobcat in 32nm, Fusion products in the first half of 2010. That would suggest that you either have taped out or is close to taping out all those products. Can you give us some sense off where you are in terms of the development on those cores?

Rick Bergman: We don't really give out inner milestones, but we, obviously you know how the semiconductor industry works. You know, June of 2010 is 7 months from now, it takes a few months to build these things so I don't think your comments are off-target at all we are, we're loading up the gun getting ready with our next wave of these fantastic products

Journalist: You mentioned, I think the roadmap for Global Foundries showed that you had, that they were doing 32nm in the second half of 2010. So how do you actually get those built in the first half?

Dirk Meyer: That was a production question.

Emilio Ghiraldi: That's manufacturing ramp, which is consistent with the...

Journalist: So they are doing the tape-outs now?

Rick Bergman: Oh yeah, absolutely and we have running material, we have material.

[Oliverda]

"The AMD executives said the company will begin shipping its Fusion line of integrated CPU-GPU products late in 2010. The integrated Fusion products will compete for market share with the discrete graphics processors, Meyer said. AMD is expected to ship Fusion first on a silicon-on-insulator (SOI) technology, and follow that with a bulk Fusion product."

^is that the 32nm Llano we saw with 400SPs? due late this year?

Yes it is. (with ~480SP)

I have a feeling that the evergreen refresh and fusion release will be together...

[Behemot]

I have a feeling that the evergreen refresh and fusion release will be together...

Any reason for that? Graphics are bulk, Fusion SOI completely...it usually has different cycles. Could be close, bot not exactly same time.

[marten_larsson]

The process is probably not that interesting from a marketing perspective.. To release it together with a new platform seems like a good idea to me.

You'd have all of their partners up in arms. These seem like hdtv/laptop/lowed laptop type deals to compete against the ion platforms for the next couple years. Maybe if these chips had cache like a 955 worth looking into. But for now I'm not sure why anyone is excited to be honest?

Think about it is right, MSI, Gigabyte, XFX, ASUS, ect ect ect video card sales would drop. The motherboard industry for them would practically cease. If all you need to do is keep upgrading your chip w/gpu then occasionally upgrade your mobo you sure wouldn't need to buy a motherboard much. I think the only way AMD would make these guys happy if they change sockets every 2 years to keep them in some sort of business. Most of these companies will die off if this is the case.
