The Radeon Xpress 1270 IGP was a mobile integrated graphics solution by ATI, launched in February 2007. Built on the 80 nm process, and based on the RS690T graphics processor, the card supports DirectX 9.0b. 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 IGP is connected to the rest of the system using a PCIe 1.0 x16 interface.
