The Radeon X800 XT Platinum was a high-end graphics card by ATI, launched on March 1st, 2004. Built on the 130 nm process, and based on the R423 graphics processor, in its R423 XT variant, the card supports DirectX 9.0b. Since Radeon X800 XT Platinum does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The R423 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 Radeon X800 XT Platinum, 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 draws power from 1x 6-pin power connector, with power draw rated at 63 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X800 XT Platinum is connected to the rest of the system using a PCI-Express 1.0 x16 interface. Its price at launch was 499 US Dollars.
