AMD might not devote quite as many resources to pimping its GPGPU efforts as Nvidia, but that doesn't mean it's not working hard on the concept. As a matter of fact, AMD has just unveiled a new version of its Stream SDK—the development toolkit that lets coders write general-purpose apps to run on Radeon graphics processors.

# Support for Microsoft Windows Vista® operating system (32-bit and 64-bit) and DirectX® 9 and DirectX 10 interoperability under Windows Vista
# Support for ATI Radeon™ HD 4850 and ATI Radeon™ HD 4870 graphics processors
# Support for ATI Catalyst™ 8.8 Display Driver
# A new unified user’s guide comprised of the most important information for developers
# Improved sample browser format and documents
# Performance enhancements to Brook+, in addition to Windows Vista OS and ATI Radeon support

Developers can grab the new SDK from the stream computing section of AMD's website in Windows XP, Windows Vista, and Linux flavors. There's more where that came from, too. AMD says it plans to release "a series of upgrades" to the Stream SDK over the coming year-and-a-half. The company aims for eventual "balanced adoption and support" of both DirectX 11 and OpenCL application programming interfaces.
