The graphics processing unit (GPU) codenamed Radeon R600 is the foundation of the Radeon HD 2000 series and the FireGL 2007 series video cards developed by ATI Technologies. The HD 2000 cards competed with nVidia's GeForce 8 series.
This article is about all products under the brand "Radeon HD 2000 Series". They all contain a GPU which implements TeraScale 1, ATI's first Unified shader model microarchitecture for PCs.
The Unified Video Decoder (UVD) SIP core is on-die in the HD 2400 and the HD 2600. The HD 2900 GPU dice do not have a UVD core, as its stream processors were powerful enough to handle most of the steps of video acceleration in its stead except for entropy decoding and bitstream processing which are left for the CPU to perform.
HDTV encoding support is implemented via the integrated AMD Xilleon encoder; the companion Rage Theater chip used on the Radeon X1000 series was replaced with the digital Theater 200 chip, providing VIVO capabilities.
For display outputs, all variants include two dual-link TMDS transmitters, except for HD 2400 and HD 3400, which include one single and one dual-link TMDS transmitters. Each DVI output includes dual-link HDCP encoder with on-chip decipher key. HDMI was introduced, supporting display resolutions up to 1,920×1,080, with integrated HD audio controller with 5.1-channel LPCM and AC3 encoding support. Audio is transmitted via DVI port, with specially designed DVI-to-HDMI dongle for HDMI output that carries both audio and video.
