AMD is working on a new multi-GPU technology called CrossFireX:
Later this year AMD plans to announced new ATI CrossFireX multi-GPU technology that will bring such benefits as 3- and 4-way CrossFire, CrossFire Overdrive, hybrid CrossFire and other features that are set to improve performance, compatibility, scalability and flexibility of ATI’s multi-GPU technology, sources close to AMD told X-bit labs.
The new technology will be supported by AMD’s forthcoming chipsets, including AMD 790X and AMD 790 FX that feature PCI Express Gen. 2 as well as various graphics cards, such as ATI Radeon HD 2600-series, ATI code-named RV670-series and, perhaps, ATI Radeon HD 2900 XT/Pro/GT graphics cards. Currently AMD’s graphics product group is mulling on exact configurations and specifications to be supported via CrossFireX.
Since at the moment AMD can hardly offer the highest-performing graphics solution on the market, it is projected that the company will push its triple and quad CrossFire configurations consisting of three or four graphics cards based on ATI RV670 against Nvidia SLI and Nvidia triple SLI configurations. Even though when it comes to 3-way and 4-way graphics processing actual rendering performance is fully dependent on drivers, ATI tells its partners that the technology will deliver benefits in key DirectX 10 games, such as Bioshock, Call of Juarez, Company of Heroes, Crysis and Lost Planet.
