Sapphire appears to be preparing to unleash a factory overclocked dual GPU card called the Radeon HD 7990 Atomic. EXPReview managed to uncover several photos and specification details of the upcoming graphics card. It is quite an impressive card, that features a custom PCB, beefy power delivery electronics, 6GB of total GDDR5, and (best of all) two AMD Radeon HD 7970 GPUs cooled by a full cover closed loop water cooler!

The Sapphire HD 7990 Atomic is based around a custom 12-layer PCB. The card also features an 18-phase VRM, 50A chokes, LFPAK MOSFETS, and Tantalum capacitors. Sapphire has divided the total 18-phase VRM up such that each GPU and 3GB of memory gets 6+2+1 power phases. Of course, the HD 7990 Atomic uses two AMD Radeon HD 7970 GHz Edition GPUs for a total of 4,096 stream processors.

Sapphire has not released clockspeed information, but it should be overclocked significantly beyond the company’s existing dual gpu 7990 card’s base and boost clockspeeds of 950 MHz and 1000 MHz.

Other features include a PLX PEX8747 PCI-E 3.0 bridge chip that connects the two 7970 GPUs together, a dual BIOS switch that will allow users to run the 7990 at stock or at overclocked speeds, and a single crossfire connector to enable quad-Crossfire multi-GPU setups. The graphics card is powered by three 8-pin PCI-E power connectors. Finally, it provides six mini-DisplayPort video outputs.

In order to effectively cool the factory overclocked card, Sapphire is bundling a pre-installed self-contained liquid cooler. The closed loop cooler consists of a full cover water block on the HD 7990 Atomic, a 240mm radiator with two 120mm fans, and a combination pump and reservoir that fits within a 5.25” optical drive bay.

Naturally, how much this card will cost and where it will be available is still unknown. With that said, ChipLoco indicates that the card is coming sometime within the “next few weeks.” The extent of the factory overclock is also unknown. It is definitely a high end card worthy of enthusiasts and overclockers. Unfortunately, it utilizes a custom PCB, so it may be difficult to find alternative blocks should users wish to integrate it into their existing custom water loops.

For GPU accelerated applications such as CAD there are only two main choices, AMD's FirePro or NVIDIA's Quadro series.  Legit Reviews got their hands on two of the three new cards from AMD, the $1600 W9000 and the $900 W8000, with the $600 W5000 missing in this review.  The results were good, the new generation cards perform better than their predecessors though in some tests only by a slim margin.  It is possible that more mature drivers will see the performance increase on those test to the large gap present in most of the other tests.  AMD has also kept the power requirements reasonable which is very important considering the huge improvement in efficiency displayed by NVIDIA's new architecture.

"AMD has successfully brought the new GCN architecture to the workstation! We noticed some pretty nice performance gains in the FirePro W8000 and W9000 cards from the previous generation of AMD FirePro graphics cards. The AMD FirePro W9000 is impressive on paper as it has 2048 stream processors running at 975MHz, 6GB of ECC GDDR5 memory at 1375MHz and the ability to drive six monitors! In some benchmarks the AMD FirePro W9000 blew away the previous generation FirePro V8800 video card, but in others it was..."
