The Radeon X800 GT AGP was a graphics card by ATI, launched on November 8th, 2007. Built on the 130 nm process, and based on the R420 graphics processor, in its R420 LE variant, the card supports DirectX 9.0b. Since Radeon X800 GT 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 8 pixel shaders and 6 vertex shaders, 8 texture mapping units, and 8 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 GT AGP, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 473 MHz, memory is running at 493 MHz.
Being a single-slot card, the ATI Radeon X800 GT AGP draws power from 1x Molex power connector, with power draw rated at 40 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X800 GT AGP is connected to the rest of the system using an AGP 8x interface.
