The Radeon X850 XT Platinum was a high-end graphics card by ATI, launched on December 21st, 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 Platinum 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 Platinum, 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.
Being a dual-slot card, the ATI Radeon X850 XT Platinum draws power from 1x 6-pin power connector, with power draw rated at 67 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon X850 XT Platinum is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card's dimensions are 186 mm x 111 mm x 41 mm, and it features a dual-slot cooling solution. Its price at launch was 549 US Dollars.
