The Radeon X800 GTO2 was a graphics card by ATI, launched in September 2005. Built on the 130 nm process, and based on the R480 graphics processor, in its R480 variant, the card supports DirectX 9.0b. Since Radeon X800 GTO2 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The R480 graphics processor is an average sized chip with a die area of 297 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 Radeon X800 GTO2, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 490 MHz.
Being a single-slot card, its power draw is not exactly known. Display outputs include: 2x DVI, 1x S-Video. Radeon X800 GTO2 is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
