The Radeon HD 8970 OEM was a graphics card by AMD, launched in January 2013. Built on the 28 nm process, and based on the Tahiti graphics processor, in its Tahiti XT variant, the card supports DirectX 12.0. The Tahiti graphics processor is a large chip with a die area of 352 mm² and 4,313 million transistors. It features 2048 shading units, 128 texture mapping units and 32 ROPs. AMD has placed 3,072 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 925 MHz, memory is running at 1375 MHz.
Being a dual-slot card, the AMD Radeon HD 8970 OEM draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 250 W maximum. Display outputs include: 1x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 8970 OEM is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 274 mm in length, and features a dual-slot cooling solution.
