AMD Announces Radeon HD 7990 "Malta" Flagship Graphics Card

AMD announced its flagship graphics card for this generation of GPUs, the Radeon HD 7990. Although essentially a dual-GPU solution based on two 28 nm "Tahiti" chips, the card is touted to be different from the various HD 7990 "New Zealand" graphics cards launched in Q3-2012, in featuring significantly lower power draw, a 2-slot cooling solution that, according to AMD, is "whisper quiet," and the need for just two 8-pin PCIe power connectors. In comparison, most "New Zealand" cards required three power connectors, and triple-slot cooling solutions.

The Radeon HD 7990 uses a pair of 28 nm "Tahiti" GPUs with all components unlocked, featuring 2048 stream processors based on the Graphics CoreNext architecture (4096 in total), 128 TMUs (256 in total), 32 ROPs (64 in total), and the full 384-bit wide GDDR5 memory interface. Each GPU holds 3 GB of memory totaling the card's memory amount to 6 GB. The GPUs feature clock speeds of 1000 MHz core, PowerTune with Boost, and a memory clock speed of 6.00 GHz, yielding 288 GB/s of memory bandwidth per GPU. The two GPU systems are tied to the system bus using a PLX PEX8747 48-lane PCI-Express 3.0 switch. 

The new Radeon HD 7990 draws power from two PCIe power connectors. Display outputs include four mini-DisplayPort, and a dual-link DVI. The card can pair with any other Radeon HD 7900 series graphics card. It features dual-BIOS, letting you fall back to a failsafe BIOS, in case you botch up BIOS updates. 

With the Radeon HD 7990, AMD is giving away eight free games, including Far Cry 3, Far Cry 3: Blood Dragon, Crysis 3 Hunter Edition, Bioshock: Infinite, Tomb Raider (2013), Hitman Absolution, Sleeping Dogs, and Deus Ex: Human Evolution. 

AMD is pricing the card on par with NVIDIA's GeForce GTX 690, at $999.
