The Radeon HD 7990 is a high-end graphics card by AMD, launched in April 2013. Built on the 28 nm process, and based on the Malta graphics processor, the card supports DirectX 11.2. The Malta graphics processor is a large chip with a die area of 365 mm² and 4,313 million transistors. Radeon HD 7990 combines two graphics processors to increase performance. It features 2048 shading units, 128 texture mapping units and 32 ROPs per GPU. AMD has placed 6,144 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface per GPU (each GPU manages 3,072 MB). The GPU is operating at a frequency of 950 MHz, which can be boosted up to 1000 MHz, memory is running at 1500 MHz.
We recommend the AMD Radeon HD 7990 for gaming with highest details at resolutions up to, and including, 5760x1080.
Being a dual-slot card, the AMD Radeon HD 7990 draws power from 2x 8-pin power connectors, with power draw rated at 375 W maximum. Display outputs include: 1x DVI, 4x mini-DisplayPort. Radeon HD 7990 is connected to the rest of the system using a PCIe 3.0 x16 interface. The card measures 307 mm in length, and features a dual-slot cooling solution. Its price at launch was 999 US Dollars.
