320-stream processors, named ATI Radeon HD 2900

AMD has named the rest of its upcoming ATI Radeon DirectX 10 product lineup. The new DirectX 10 product family received the ATI Radeon HD 2000-series moniker. For the new product generation, AMD has tagged HD to the product name to designate the entire lineup’s Avivo HD technology. AMD has also removed the X-prefix on its product models.

At the top of the DirectX 10 chain, is the ATI Radeon HD 2900 XT. The AMD ATI Radeon HD 2900-series features 320 stream processors, over twice as many as NVIDIA’s GeForce 8800 GTX. AMD couples the 320 stream processors with a 512-bit memory interface with eight channels. CrossFire support is now natively supported by the AMD ATI Radeon HD 2900-series; the external CrossFire dongle is a thing of the past.

The R600-based ATI Radeon HD 2900-series products also support 128-bit HDR rendering. AMD has also upped the ante on anti-aliasing support. The ATI Radeon HD 2900-series supports up to 24x anti-aliasing. NVIDIA’s GeForce 8800-series only supports up to 16x anti-aliasing. AMD’s ATI Radeon HD 2900-series also possesses physics processing.

The entire AMD ATI Radeon HD 2000-family features the latest Avivo HD technology. AMD’s upgraded Avivo with a new Universal Video Decoder, also known as UVD, and the new Advanced Video Processor, or AVP. UVD previously made its debut in the OEM-exclusive RV550 GPU core. UVD provides hardware acceleration of H.264 and VC-1 high definition video formats used by Blu-ray and HD DVD. The AVP allows the GPU to apply hardware acceleration and video processing functions while keeping power consumption low.
