The Radeon Xpress 1270 Mobile IGP was a mobile integrated graphics solution by ATI, launched on February 28th, 2007. Built on the 80 nm process, and based on the RS690 graphics processor, in its RS690M variant, the device supports DirectX 9.0b. Since Radeon Xpress 1270 Mobile IGP does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. It features 4 pixel shaders and 2 vertex shaders, 4 texture mapping units, and 4 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). The GPU is operating at a frequency of 400 MHz. Its power draw is not exactly known. Radeon Xpress 1270 Mobile IGP is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
The Radeon Xpress IGP is embedded into the AMD RS690M northbridge.
