ATI Radeon X1950 PRO DUAL Image ATI RV570 Image
The Radeon X1950 PRO DUAL was a performance graphics card by ATI, launched in January 2007. Built on the 80 nm process, and based on the RV570 graphics processor, the card supports DirectX 9.0c. The RV570 graphics processor is an average sized chip with a die area of 230 mm² and 330 million transistors. Radeon X1950 PRO DUAL combines two graphics processors to increase performance. It features 36 pixel shaders and 8 vertex shaders, 12 texture mapping units and 12 ROPs per GPU. 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 1,024 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 512 MB). The GPU is operating at a frequency of 575 MHz, memory is running at 690 MHz.
We recommend the ATI Radeon X1950 PRO DUAL for gaming with highest details at resolutions up to, and including, 1280x720.
Being a single-slot card, the ATI Radeon X1950 PRO DUAL draws power from 1x 6-pin power connectors, with power draw rated at 130 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon X1950 PRO DUAL is connected to the rest of the system using a PCIe 1.0 x16 interface. The card measures 300 mm in length, and features a single-slot cooling solution. Its price at launch was 349 US Dollars.
