The upcoming RS600 integrated graphics chipset from ATI may lack support for Shader Model 3.0, The Tech Report heard.
According to HKEPC the chip is based on the Radeon X700 GPU, it will be launched next month.
NVIDIA's GeForce 6100 and 6150 IGP chipsets support DirectX Shader Model 3.0, and Intel's G965 Express is expected to do the same. ATI's RS600, however, will support only Shader Model 2.0. HKEPC claims ATI is planning to skip the Shader Model 3.0 generation altogether with its onboard graphics and move on to Shader Model 4.0 and DirectX 10 in its future RS700 chipset. Little is known about the RS700, but it will reportedly show up in mid-2007 and support hardware acceleration for both Blu-ray and HD-DVD media.
