AMD releases ATI Catalyst 8.3 drivers, enables CrossFireX
Get ready to burn through your allowance, kids, as AMD is getting set to loose its Catalyst 8.3 drivers for all to indulge in. What does the download net you, exactly? Why, CrossFireX support, of course. Starting today, users can link up any combination of RV670- and R680-based products -- that includes the Radeon HD 3850, Radeon HD 3870 and Radeon HD 3870 X2 -- in order to acquire triple- and quad-GPU performance within Windows Vista. Additionally, the drivers also introduce ATI Hybrid Graphics support in Vista, which was boasted about already when the firm unveiled its upcoming 780G chipset. Check out the read link for the full list of changes, and keep an eye on the firm's support page for v8.3 to surface any moment now.
ATI demonstrates hybrid-chip CrossFire graphics tech
We've already seen laptops like Sony's Vaio SZ include integrated graphics alongside much more powerful (and power-hungry) dedicated chips, but AMD's looking to make such setups all the more commonplace with new chips capable of hybrid CrossFire. AMD recently demoed the tech to PC Perspective, showing off a 2.2GHz Phenom machine with both unreleased RS780 integrated graphics and a RV620-based card labeled HD Radeon 3450. Running games like Call of Duty 4 and Unreal Tournament 3, frame rates jumped from 30-35fps to around 55fps when hybrid mode was enabled. That's pretty respectable, although the system is limited to speedups of the slowest chip times two, so bigger gains are probably not in the offing. However, there can still be benefits to using chips of drastically different horsepower: the integrated chips can power down the heavy hitter to save power when not needed, and totally switch over when required. That's a pretty solid compromise, we think -- and with AMD aiming for the initial batch of hybrid CrossFire-capable cards to be priced around $50, it looks like we'll be seeing these setups a lot when AMD starts shipping these early next year.
