Tul Corp., the company behind PowerColor supplier of graphics card, has introduced the world's first graphics card that uses two AMD Radeon HD 7970 "Tahiti XT" graphics processing units (GPUs). The PowerColor Devil 13 HD 7990 graphics board uses the company's own design of printed-circuit board and a proprietary triple-slot cooling system.
PowerColor Devil 13 HD7990 graphics card features two Radeon HD 7970 "Tahiti XT" GPUs operating at 925MHz with default settings and at 1GHz once a special setting inside the BIOS is activated. The board carries 6GB of GDDR5 memory operating at 5.5GHz (3GB of memory with 384-bit memory bus per chip) and has DL DVI-I, SL DVI-D, HDMI, two miniDisplayPort connectors. The most powerful AMD Radeon HD-based graphics card requires 850W power supply unit that has three 8-pin PCI Express power connectors.
Thanks to two AMD Tahiti XT graphics chips, the dual-chip Devil 13 graphics solution has 4096 stream processors, 256 texture units, 64 render back ends and so on. The novelty is expected to set up a new performance bar for AMD-based graphics solution and will rival Nvidia Corp.'s GeForce GTX 690 graphics card.
The Devil 13 HD7990 is built with high efficiency thermal solution and solid components onboard. With trio fans and 10pcs U-shape heat pipes, maximizing the heat dissipated ability to cool down the Devil 13 board. Also, it includes 12+2+2 phases, digital PWM, super cap, UHB and PowerIRstage - all these platinum power kit enhances stability and reliability voltage for GPU with minimum conduction losses and lower temperatures at load, delivering the steadiest and most secure power to boost for performance.
Although AMD has managed to release the world's first graphics processing unit (GPU) made using 28nm process technology, the Radeon HD 7900 "Tahiti", it has evidently failed to develop a dual-chip flagship graphics card powered by two of such chips. The arch-rival of AMD, Nvidia was several months late with its first 28nm GPU, but was quick enough to launch its dual-chip graphics board for enthusiasts in late April. Apparently, select partners of AMD are capable of developing dual-chip flagship graphics solutions themselves. In fact, PowerColor first demonstrated its Devil 13 graphics card in late May, but the solution will reach the market only in late August or even September.
The Devil 13 HD7990 comes bundled with Wiha tool kit with multiple reversible blades set as well as PowerColor PowerJack, the professional graphics card supporter which provides the powerful force to support the weight of the card from the back, avoiding card bending in the case.
Pricing of PowerColor HD7990 is unknown. Considering the fact that one Radeon HD 7970 GHz Edition costs $499, the dual-chip solution will hardly cost a lot less than $999...
