ATI Radeon X850 XT Platinum Image ATI R480 Image
The Radeon X850 XT Platinum was a graphics card by ATI, launched in December 2004. Built on the 130 nm process, and based on the R480 graphics processor, the card supports DirectX 9.0b. The R480 graphics processor is an average sized chip with a die area of 297 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 540 MHz, memory is running at 590 MHz.
We recommend the ATI Radeon X850 XT Platinum for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, its power draw is rated at 67 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X850 XT Platinum is connected to the rest of the system using a PCIe 1.0 x16 interface.
