ATI Radeon X850 XT AGP Image ATI R481 Image
The Radeon X850 XT AGP was a graphics card by ATI, launched in February 2005. Built on the 130 nm process, and based on the R481 graphics processor, in its R481 XT variant, the card supports DirectX 9.0b. The R481 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 520 MHz, memory is running at 540 MHz.
We recommend the ATI Radeon X850 XT AGP for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, the ATI Radeon X850 XT AGP draws power from 1x Molex power connectors, with power draw rated at 69 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X850 XT AGP is connected to the rest of the system using an AGP 8x interface.
