Folks who couldn't muster the courage to install AMD's "pre-certified" driver can now download a Microsoft-approved version. Catalyst 12.2 brings several worthwhile updates over the last stable release, though there doesn't seem to be any changes from last month's pre-certified build -- that includes a lack of support for the Radeon HD 7000 series on Windows XP, so you'll need Vista or 7.
Catalyst 12.2 totes bug fixes for games including Tom Clancy's HAWX, Modern Warfare 3, Dragon Age 2, Battleforge, Bad Company 2, StarCraft II, Arkham City, Crysis Warhead, World of Warcraft and Dirt 3. Various bugs involving Blu-ray playback have also been squashed, while a few new glitches pertaining to Alan Wake and Skyrim have been added to the release notes since the pre-certified version.
Along with adding support for super sampling anti-aliasing in DX10 and 11 applications, Catalyst 12.2 improves Eyefinity 2.1 by enabling custom resolutions, dynamic configuration changes (physically plugging/unplugging displays will automatically load the right profile), HydraVision enhancements (the Windows Taskbar can now be moved and resized), and various tweaks to the Profile Manager.
The latest Radeons aren't fully supported on Windows 8 yet either, though AMD promises that in the coming weeks. Other GPU generations can use last week's Catalyst Driver 8.93.7 RC10 to tap into WDDM 1.2, which includes native Stereo 3D support for full screen and windowed gaming, optimized screen rotation and power consumption, as well as improved sleep and resume performance.
The HD 7950 has 2048 SPUs, 128 TAUs and 32 ROPs. The only other ports are on the I/O panel where you'll find a dual DL-DVI connector, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets. Supports a max resolution of 2560x1600 on up to 3 monitors.
The AMD ATI Radeon HD 7770 measures 21cm (8.2in) long, the GPU core runs at 1GHz, it comes loaded with a 1GB frame buffer, the Radeon HD 7770 also carries 640 SPUs, 40 TAUs and 16 ROPs. The HD 7770 operates at near silence because even under load it only draws 80 watts and as little as 3 watts at idle, courtesy of the ZeroCore Power technology. Last but not least, AMD has included a single 6-pin PCI Express power connector.
The Radeon HD 7750 measures only 17cm (6.6in) long and operates at 800MHz. The HD 7750 reference card has a single slot cooler that uses a low-profile heatsink and fan measuring 3cm tall. The heatsink itself is 9.5cm long, 7.5cm wide and is cooled by a 65mm fan. The I/O panel has a dual DL-DVI connector, a single HDMI 1.4a port and a DisplayPort 1.2 socket.
