The Mobility Radeon X800 XT was a mobile graphics chip by ATI, launched on June 1st, 2005. Built on the 130 nm process, and based on the M28 graphics processor, in its M28 X800 XT variant, the chip supports DirectX 9.0b. Since Mobility Radeon X800 XT does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The M28 graphics processor is an average sized chip with a die area of 289 mm² and 160 million transistors. It features 16 pixel shaders and 6 vertex shaders, 16 texture mapping units, and 16 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). ATI has paired 256 MB GDDR3 memory with the Mobility Radeon X800 XT, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 480 MHz, memory is running at 550 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Mobility Radeon X800 XT is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
