AMD's "RV610" and "RV630" are the codenames behind their next-gen value and midrange graphics cards, these being DX10 cards with support for shader model 4.0 and AVIVO high-definition video playback as well.

The DailyTech have sourced a bunch of info on 'em recently as per this article.

AMD's next-generation value and mainstream products are set to bring DirectX 10 and high-definition video playback to the masses. Although AMD is late to the DirectX 10 game, the upcoming RV610 and RV630 feature second-generation unified shaders with shader model 4.0 support. AMD has remained hush over the amount of unified shaders and shader clock speeds of its next-generation value and mainstream products though.

AMD is prepared to take on NVIDIA's PureVideo HD with its next-generation AVIVO video processing. AVIVO is receiving its first upgrade since its introduction with the Radeon X1k-series with the RV610 and RV630. This time around, AMD is integrating its Universal Video Decoder, or UVD, for hardware decoding of H.264 and VC-1 high-definition video formats.

Also nudging closer is the upcoming launch of NVIDIA's answer to the above; these being NVIDIA's 8600GTS, 8600GT and 8500GT. Dailytech have just acquired some more info on these babies too, along with a couple piccies for good measure.

Earlier today DailyTech received it's briefiing on NVIDIA's upcoming GeForce 8600GTS, 8600GT and 8500GT graphics processors. NVIDIA's GeForce 8600GTS and 8600GT are G84-based GPUs and target the mid-range markets. The lower-positioned G86-based GeForce 8500GT serves as the flagship low to mid-range graphics card.

The budget-priced trio feature full support for DirectX 10 features including pixel and vertex shader model 4.0. NVIDIA has yet to reveal the amount of shaders or shader clocks though. Nevertheless, the trio supports NVIDIA SLI and PureVideo technologies.
