ATI Radeon X800 XT Platinum Image ATI R423 Image
The Radeon X800 XT Platinum was a graphics card by ATI, launched in March 2004. Built on the 130 nm process, and based on the R423 graphics processor, the card supports DirectX 9.0c. 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 placed 256 MB GDDR3 memory on the card, 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.
We recommend the ATI Radeon X800 XT Platinum for gaming with highest details at resolutions up to, and including, 1280x720.
Being a single-slot card, the ATI Radeon X800 XT Platinum draws power from 1x 6-pin power connectors, 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 PCIe 1.0 x16 interface.
