" AMD packed ATI Catalyst 8.3 with a double-barreled set of leading technologies to simultaneously push the Ultimate Visual Experience(TM) to new heights and to a wider population of PC users," said Rick Bergman, senior vice president, AMD Graphics Product Group. "We deliver industry firsts that make a visible difference to PC users, whether it's CrossFireX and the first ever quad-GPU performance on Windows Vista, or ATI Hybrid Graphics that bring a new level of performance to mainstream PC platforms."
Advancing Multi-GPU Gaming with CrossFireX
Through three- and four-GPU configurations in CrossFireX, gamers can see multi-GPU performance scaling across a range of today's most popular DirectX(R) 9 and DirectX(R) 10 games on Windows Vista -- up to 3.2 times the performance over a single GPU(2) in some scenarios. The flexible architecture of CrossFireX allows for the mixing and matching of high-performing ATI Radeon(TM) GPUs. Any ATI Radeon(TM) HD 3850, ATI Radeon(TM) HD 3870 or ATI Radeon(TM) HD 3870 X2 cards can be combined to harness the power of up to four GPUs. CrossFireX also supports a wide range of platforms, enabling many gamers to take advantage of three- and four-GPU gaming on their existing hardware.
Boosting Game Performance through ATI Hybrid CrossFire
ATI Catalyst 8.3 also introduces ATI Hybrid Graphics support for Windows Vista. An industry first that is unique to AMD processor-based platforms, ATI Hybrid CrossFire(TM) delivers a significant 3D performance boost. Up to 70 percent increases in performance are possible in some gaming scenarios(3) based on PCs comprised of an AMD 780G motherboard and ATI Radeon HD 3400 Series graphics product in Windows Vista. ATI Hybrid Graphics also support up to four independent displays through the SurroudView(TM) feature for those who want to maximize productivity.
Additional Innovations Found in ATI Catalyst 8.3
Beyond multi-GPU configurations in CrossFireX, ATI Catalyst 8.3 introduces a number of new features including:
-- DirectX 10.1 and Tessellation Support: ATI Catalyst 8.3 marks the first time DirectX 10.1 support for the ATI Radeon(TM) HD 3000 series, and tessellation support for the ATI Radeon(TM) HD 3800 series have been made available to developers.
-- Anti-Aliasing enhancements: ATI Catalyst introduces anti-aliasing support for all Unreal Engine 3.0-based games running in DirectX 9 mode. ATI Catalyst also allows users to enable the Custom Filter Anti-Aliasing filters (box and wide tent) while running in CrossFire Super Anti-Aliasing modes, providing superior image quality.
-- HydraVision(TM) support for Windows Vista: HydraVision support is now included in ATI Catalyst Control Center for Windows Vista. HydraVision enables users to efficiently organize multiple applications across single or multiple displays. You may configure up to nine virtual desktops, and divide the Windows Vista desktop into definable areas helping to easily move and organize multiple applications.
-- Digital Panel GPU image scaling: For those using widescreen displays, ATI Catalyst now allows users to enable GPU-accelerated scaling to maintain the aspect ratio of the display while providing superior image quality.
-- Advanced Video Quality controls: With ATI Catalyst 8.3, multimedia enthusiasts get further control over video quality. Using the new edge enhancement feature, the level of sharpness of video content can be adjusted. Through the new noise reduction feature, ghosting artifacts can be removed while preserving the details of the original video. The new slider controls can be found in the All Settings page of the Avivo(TM) Video tab found in ATI Catalyst Control Center.
ATI Catalyst 8.3 is scheduled to be available as a free download starting Tuesday, March 4 online at http://ati.amd.com/support/driver.html.

1. Based on AMD benchmark results that demonstrate a performance/$ ratio in favor of ATI Radeon GPUs vs. competing Nvidia GeForce GPUs. Cost per 3DMark determined based on AMD internal benchmark results in 3DMark06 v184.108.40.206 at 1920x1200 4xAA 8xAF on an ASUS P5E (X38) or EVGA 780i platform running an Intel X9650, 2GB DDR2-800 (5-5-5-12 timings), Windows Vista RTM 64bit, and 8.471-Beta2_080214a-059709E-ATI or ForceWare 169.28beta. Based on the average price at Newegg.com as of March 3, 2008, two ATI Radeon(TM) HD 3870 X2 cards at $900, and two Nvidia GeForce 8800 GTX cards at $900, two ATI Radeon(TM) 3870 X2 cards combine to score 16412 3DMarks while two GeForce 8800 GTX cards combine to score 12748 3DMarks resulting in the two ATI Radeon(TM) HD 3870 X2 cards delivering 28% more performance for the same price as the Nvidia solution.
2. Based on AMD benchmark results in Supreme Commander (2560x1600x32 8xAA 16xAF quality=Very High) and Unreal Tournament 3 (2560x1600x32 4xAA 16xAF dxmode=dx9) on an AMD Phenom 2.6GHz platform, using MSI K9A2 Plat (790FX) motherboard, 2GB DDR2-800 (5-5-5-12 timings), Windows Vista RTM 64bit, ATI Catalyst 8.3 beta drivers and Forceware drivers 169.28 Beta. Comparing the performance of two ATI Radeon(TM) HD 3870 X2 cards vs. one ATI Radeon(TM) HD 3870 card, Supreme Commander exhibits 3.32 times the performance of the single card when using quad CrossFireX, and Unreal Tournament 3 exhibits 3.23 times the performance of the single card when using quad CrossFireX.
3. Based on AMD benchmark results in 3DMark06 (1280x1024), Quake 4 (1600x1200 HQ), Prey (1280x1024) and FarCry (1600x1200) on an AMD Phenom 2.3 GHz platform using MSI K9A2 Plat (790FX) motherboard, 2GB DDR2-800 (5-5-5-12 timings), Windows Vista RTM 64bit, ATI Catalyst 8.3 beta drivers. With ATI Hybrid CrossFire enabled, the four applications listed above exhibit at least 1.7 times the performance of stand-alone integrated graphics on the AMD780G motherboard without ATI Hybrid CrossFire enabled.
