Information about the future successors of the RV610 and RV630, found respectively in the Radeon HD 2400 and 2600, has been unearthed. The always unable to keep a secret sources close to graphics card manufacturers told DigiTimes that AMD's DirectX 10.1 entry-level and mid-range graphics processor would be known under the incremental names of RV635 and RV620.
Manufactured at TSMC like their predecessors, these two new chips will be fabricated on a 55nm half-node process, whereas current Radeon HD 2400 and 2600-powering chips are 65nm products. Additionally to their new manufacturing process, RV635 and RV620's main upgrade comes from their DirectX 10.1 compatibility, making the chips Shader Model 4.1 compliant.
The still unnamed boards, likely to be named Radeon HD 2500 and 2650 according to the same sources, will be PCI Express 2.0 and Display Port compatible. RV635 and RV620 are also expected to be pin compatible and use the same PCB design as the previous chips --RV630 and RV610—to allow add-in-board (AIB ) manufacturers a simple inventory transition between the production of old and new products.
First samples of the new chips should be sent to AIB manufacturers in October this year. These new boards should be launched by Q108, as early as January.AMD, Graphics Card, Video Card, GPUs, Radeon, DirectX 10.1, DX10.1, RV635, RV620
