The Radeon X800 GTO AGP was a graphics card by ATI, launched in November 2007. Built on the 130 nm process, and based on the R420 graphics processor, in its R420 GTO variant, the card supports DirectX 9.0b. Since Radeon X800 GTO AGP does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The R420 graphics processor is an average sized chip with a die area of 281 mm² and 160 million transistors. It features 12 pixel shaders and 6 vertex shaders, 12 texture mapping units, and 12 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 GTO AGP, 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, the ATI Radeon X800 GTO AGP draws power from 1x Molex power connector, with power draw rated at 49 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X800 GTO AGP is connected to the rest of the system using an AGP 8x interface.
