The Radeon X850 XT was a high-end graphics card by ATI, launched on December 1st, 2004. Built on the 130 nm process, and based on the R480 graphics processor, in its R480 XT X850 variant, the card supports DirectX 9.0b. Since Radeon X850 XT does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. 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 paired 256 MB GDDR3 memory with the Radeon X850 XT, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 520 MHz, memory is running at 540 MHz.
Being a dual-slot card, the ATI Radeon X850 XT draws power from 1x 6-pin power connector, with power draw rated at 69 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X850 XT is connected to the rest of the system using a PCI-Express 1.0 x16 interface. Its price at launch was 499 US Dollars.
