The Radeon HD 5970 was a high-end graphics card by ATI, launched in November 2009. Built on the 40 nm process, and based on the Hemlock graphics processor, in its Hemlock XT variant, the card supports DirectX 11.0. The Hemlock graphics processor is a large chip with a die area of 334 mm² and 2,154 million transistors. Radeon HD 5970 combines two graphics processors to increase performance. It features 1600 shading units, 80 texture mapping units and 32 ROPs per GPU. ATI has placed 2,048 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 1,024 MB). The GPU is operating at a frequency of 725 MHz, memory is running at 1000 MHz.
We recommend the ATI Radeon HD 5970 for gaming with highest details at resolutions up to, and including, 2560x1440.
Being a dual-slot card, the ATI Radeon HD 5970 draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 294 W maximum. Display outputs include: 2x DVI, 1x mini-DisplayPort. Radeon HD 5970 is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 305 mm in length, and features a dual-slot cooling solution. Its price at launch was 699 US Dollars.
