AMD's January GPU launch includes the dual-GPU R680  (Source: AMD)
Get ready to enter 2008 with a bang: AMD has a bunch of GPUs on the way

AMD's newest R680 graphics processor might look a whole lot like the ill-fated R600 GPU, but the reality couldn't be more bizarre.  Instead of one 80nm behemoth-of-a-GPU, the R680 consists of two 55nm processor cores.

Representatives from AMD would not confirm that the R680 is essentially two RV670 GPU cores on the same board, though the company did confirm that each core has the same specifications of an RV670 processor.

The RV670 graphics core, announced last November with the Phenom processor, is the first 55nm desktop graphics adaptor.  AMD does not target this card as a high-end adaptor, though reviewers were quick to herald the RV670 as AMD's best product of 2007.

The company also made quick mention of the RV620 and RV635 GPU cores.  These cores are nearly identical to the previous RV610 and RV630 processors, but will be produced on the 55nm node instead. 

All three of AMD's new GPUs are scheduled to launch next month. 

Dual-GPU technology is not new.  3dfx's flagship Voodoo 5 family also resorted to multiple processors to achieve its relatively high performance.  ASUS, Gigabyte, Sapphire, HIS and PowerColor all introduced dual-GPU configurations of just about every graphics processor on the market, though these were never "sanctioned" ATI or NVIDIA projects.  Ultimately, all of these projects were canned due to long development times and low demand.

Cross-state rival NVIDIA isn't sitting on idle hands though, either.   The company publicly announced plans to replace all 90nm G80 graphics cores with G92 derivatives by the end of the year.  G92's debut introduction, GeForce 8800 GT, met wild support from reviewers and analysts alike.  G92's second introduce, GeForce 8800 GTS 512MB, was met with similar but less enthusiastic acceptance during Tuesday's launch.

NVIDIA's newest roadmap claims the DirectX 10.1 family of 65nm processors will also hit store shelves this Spring.  The chipsets -- codenamed D9E, D9M and D9P -- are architecturally different from the G80/G92 family.

RE: GeForce 9???

From what I've seen 3 x GPU isn't worth it, as hardly anything supports it effectively.

As this is in the Geforce 9 thread, I was suggesting that a Geforce 9 would be capable of running Crysis on highest everything. I'm not that interested in new Geforce 8 cards- I have one, and new ones only seem about 10 - 15 % faster, which is hardly enough to get excited over. I want a 256 pipeline, 1 GB (minimum) card to come out! It probably won't for over a year- Geforce 8's are going to be milked dry before the new ones come out. It's expensive business researching new cards and until ATI deliver something which will bring the Geforce 8's to their knees, what incentive do Nvidia have for releasing faster cards? All it will do is to reduce the amount of money they gain from the 8 series.

As much as I love AMD, I didn't like the way they released the X2 series and kept the prices at about £200 for over a year until the core 2 duos came out. I know it's the same as Intel did when they had the upper hand and AMD would be struggling even more if they hadn't cashed in on it, but businesses are businesses and competition can only be a good thing. Hopefully these new ATI cards are something super special and it will lead Nvidia to release their new series.
