The Radeon X1950 XTX Uber Edition was a enthusiast-class graphics card by ATI, launched in January 2007. Built on the 90 nm process, and based on the R580+ graphics processor, in its R580+ XT variant, the card supports DirectX 9.0c. The R580+ graphics processor is a large chip with a die area of 352 mm² and 384 million transistors. It features 48 pixel shaders and 8 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 512 MB GDDR4 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 670 MHz, memory is running at 1050 MHz.
Being a dual-slot card, the ATI Radeon X1950 XTX Uber Edition draws power from 1x 6-pin power connectors, with power draw rated at 125 W maximum. Display outputs include: 1x DVI, 1x VHDCI. Radeon X1950 XTX Uber Edition is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 230 mm in length, and features a dual-slot cooling solution. Its price at launch was 788 US Dollars.
