AMD Llano Fusion APU to Feature Radeon HD 6550 Graphics

AMD's upcoming Llano line of accelerated processing units (APUs), to compete with Intel's Sandy Bridge LGA1155 processors, is said to embed what AMD will refer to as the Radeon HD 6550 graphics core. Unlike Sandy Bridge where a processor die is simply fused with a integrated graphics northbridge onto a single die, Llano will see the GPU part of the silicon integrated with the rest of the APU in many other levels, including assisting the x86 cores with serial processing loads.

Llano's embedded GPU carries the AMD Radeon SKU of HD 6550. It will feature on AMD's Fusion A8-3550 and A8-3550P APUs, is DirectX 11 compliant, has 400 stream processors, and a core clock speed of 594 MHz. It uses memory shared from the main memory, but in all likelihood, AMD might work on SidePort-based memory support. Further, the Radeon HD 6550 can work in tandem with discrete AMD Radeon HD 6570 and HD 6670 "Turks" based graphics cards in the same way as AMD's IGPs have been known to work with entry-level Radeon GPUs using Hybrid CrossFireX. When the HD 6550 iGPU is working in tandem with HD 6670 or HD 6570, the graphics hardware will be recognized as "Radeon HD 6690".

I think this time frame will work out well for my next Laptop purchase. Will be a nice step up from my mobile 8600gs :o

Ya 400sp is quite a lot but we have to remember that it is clocled a lot slower than most dedicated GPUs and doesn't have ot's own memory. My guess is that performance will be around hd4670/hd5550 levels

I think one thing a lot of people are looking past is this is just an early model, how many SP's do you think the next gen or the gen after will have?

Think about it, in its current form it can play games (mainly on lower settings) but in a generation or two fusion APU's should be more than powerful enough for pretty much all mainstream gaming, no maxed settings on newer games but compare that to current on board gpu's that the majority use.

Fusion APU's and Intel's on chip GPU's are a great thing for pc gaming as more and more users will have the power to game.

true, but pair that in crossfire with the current onboard igp on the mobos and you have quite a bit of graphics performance for such a low power integrated solution.

Even at 1080p, an 8800GT has no issues with most popular games. WoW, CoD, CS1.6, SC2, Portal 2...

Sure, Crysis will have issues, and BF3, and Metro 2033, but even then you'd get away with it on lowered settings (contrary to what some PC hardware reviews suggest, games are still fun on low graphics settings :P).

gpu-z of 8800 GT shows 57 gb/sec

http://gpuz.techpowerup.com/11/03/21/hp3.png

6.4 gb/sec for hd6300, no matter if you put more shaders and all that in there you wont get more than 128 bit (as system memory) and you will not get more than 12gb/sec max on current stars arch if it havent been changed (phenom II derived)
even if it got same as LGA1366, LGa1155 and bulldozer which sits right under 30gb/sec at 1866mhz ddr3 its still going to be half of a 8800GT.
Unless it has sideport its going to be alot slower than 8800GT in terms of texture and AA performance.
You can probably play crysis with low textures and good quality on effects, shaders and so on.

I sincerely hope they put sideport memory on the motherboards, and in laptops to gain a good 50gb/sec which is easy at 128bit, 700 mhz gddr5 will do, system shared memory is not the way forward!

I'm sure they could put on 600mhz GDDR5 chips, thats probably chips they throw cause I have never seen GDDR5 chips that works at 600mhz.
A friend of mine have a GTX470, memory errors so clocked down to 500 mhz and he could play through the lan, but the performance hit was severe, dedicated cards have its memory bandwidth for a reason, 3870 had 60gb/sec for 320sp

you dont have onboard on the motherboards with FM1 socket, no northbridge present, only crossfire with dedicated gpu HD6570 HD6550

Yeah, these Llano chips will be great for 720p gaming, and for the vast majority of people out there, that's just good enough (especially on a small computer screen). I like where AMD is heading in; why try to beat Intel in the CPU arms race when their strenghts are in graphics? A cheap Athlon II dual or quad-core chip is good enough for the vast majority of people, pair it with a powerful GPU to run graphics (where the real processing demands are) and you have one hell of a combo.

Nice. Been waiting for this since getting a 790GX board to cross with a 3470. Unfortunately it was during the start of DFI's decline and turned out to be a shoddy board. Never got around to trying out Crossfire. Then AMD didn't keep up (80sp IGP for 4350/4550, maybe a 320sp IGP for 5550), but no griping here, as I'm glad they brought back this concept with Llano!

Another thing they could bring back, pushing DTX again! Tri-Crossfire the 6550 with a couple 6570's ;)

I agree there and hope to see some sideport memory involved, say you egen take a 5670 GDDR3 and GDDR5 version, the GDDR5 version is quite noticeably faster (packing around twice the bandwidth). and I used a mobility 5650, which specs wise is extremely close to this APU, except it had DDR3 (800mhz) packing 25.6gb/s of bandwidth, clock that up to 950 and performance rose about 10-15%. this chip will need all the bandwidth it can get, provided it gets it, it will be a FANTASTIC chip for 720p gaming. let alone gen's to follow.

yeah, If they somehow upgraded the memory controller for the stars cpu's to match bulldozer's bandwidth and ran the apu at 128 bit we would see close to 26gb/sec which brings it to your laptops performance, but imagine... half of that again if it haven't.
