Advanced Micro Devices pins a lot of hopes onto performance of the integrated graphics cores of code-named Llano A-series accelerated processing units (APUs). Besides, the company believes that other performance-boosting technologies will make its A-series APUs even more competitive on the market.

According to AMD internal documents seen by X-bit labs, which describe performance of AMD's new products, AMD A8-3550 APU (quad-core, 4MB cache, 400 stream processors, Radeon HD 6550 graphics core at 594MHz) delivers three times higher performance in 3DMark Vantage test compared to Intel Core i5-2300 (quad-core, 2.80GHz/3.10GHz clock-speed, 6MB cache, Intel HD graphics core at 850MHz/1100MHz): P3335 versus P1007 marks. Besides offering more performance, the graphics core from AMD also supports DirectX 11 capabilities, whereas Intel's graphics engine features only DirectX 10.1.

The new AMD A-series APUs will also support Turbo Core technology, which will be able to overclock two out of four cores by 300MHz while disabling another couple of them. Unfortunately, the actual resulting clock-speeds are unclear and therefore it is unknown how completive will performance of Llano be against Intel Core i-series "Sandy Bridge" microprocessors.

Besides integrating high-performance graphics engine and Turbo Core technology, AMD will also promote so-called Dual Graphics technology, which will essentially be a CrossFireX capability for low-cost discrete and integrated graphics. Certain combinations of standalone graphics cards (code-named Whistler and Seymour) with integrated solutions will add up to 75% of graphics performance to systems. One of the messages that AMD wants to send is that while its discrete graphics cards provide additive performance with its platforms, Nvidia Corp.'s GeForce graphics cards do not provide additive performance on either AMD or Intel platforms.

AMD did not comment on the news-story.

GPU unit on Liano APU will have 400-500 stream procesing unit.So very strong GPU perfomance for APU.

Hope it will be a effective move for AMD team 'Cause they really need it to be...

I was expecting more from 400 stream processors, considering it is compared to the Intel HD Graphics 2000, not 3000. Really not that impressive.

Llano will provide ample combined CPU+GPU performance for 98% of users out there. It will be found in a lot of pre-built boxes and laptops from Dell Acer and HP, and the corner computer store.

That's all what AMD is after with the McLlano.

On the other hand, Bulldozer will be AMD's bid to reconquer the server market and the enthusiast desktop user.

Some test show that with Liano u be able to play Crysis and other demand game on low resolution ,so Liano will attack both market CPU and GPU at once.

Crysis is firstly an old game, and Llano will able to play it flawless both on high quality and performance my post.

The facts of this article are false.

core i5 2500k not over-clocked scores P6250 in 3DMark Vantage which is quite a ways from the proclaimed P1007 mark. See yourself at, click on results.

In any case, I still expect it to be 3 times faster than the i5 2300 which would mean we would getting about 45-50 FPS in Oblivion and Crysis. Not quite a replacement yet for you average video card. Dang! If only they can double it to 800 cores in there next release, then that might just do the trick.

They should release quote "a Gaming CPU" where performance focuses on video rather than thread performance. Sorry but the FX series are not gaming CPUs since they require additional video card.

Finally, the should allow for MAX GPU performance option in BIOS such that the main thing that is overclocked is the on-board GPU.

What is wrong? P1000 for HD Graphics 2000 is absolutely normal. For example:

If you search at for a Core i5-2500K with HD graphics 2000/3000, you find that the bulk of scores are in the 1700's. The i5-2500k, is faster then the i5-2300, so the results are slightly higher then you would expect to get for the i5-2300. So 1000-1500 is where i would expect the results to be.

Furthermore llano has 400 stream processors. It shouldn't be hard to imagine its performance as being equivalent to a low memory bit rate 400 stream processor desktop card (HD5670). Id play crysis on that at 1366x768. Any resolution much larger then that and its going to be to slow / to much turned of to really count as crysis.

This matches my expectations based on the Radeon 6450 review that the low end Llano will be slower than the HD 3000 on most games. I'm ready to be underwhelmed by Llano, but I'm sure it will still be a great value for money chip and okay for entry level gaming.

If the AMD A8-3550 APU is aimed at the i5 2300 then it is price competitive with it. The i5 2500k costs 20% more so we will have to wait for the competition for it.
