The Radeon X800 XT Platinum AGP was a graphics card by ATI, launched on May 1st, 2004. Built on the 130 nm process, and based on the R420 graphics processor, in its R420 XTP variant, the card supports DirectX 9.0b. Since Radeon X800 XT Platinum 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 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 XT Platinum AGP, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 520 MHz, memory is running at 560 MHz.
Being a single-slot card, the ATI Radeon X800 XT Platinum AGP draws power from 1x Molex power connector, with power draw rated at 63 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X800 XT Platinum AGP is connected to the rest of the system using an AGP 8x interface.
