It was only a matter of time after AMD's launch of the more energy-efficient Radeon HD 7990 "Malta" graphics card, that Sapphire would design a liquid-cooled Atomic variant. The card is based on a custom-design 12-layer PCB, ships with factory-overclocked speeds, and uses a high-grade VRM with 12-phase vGPU, 4-phase VDDCI, and 2-phase MVDD, which draw power from three 8-pin PCIe power connectors. The card is cooled by a full-coverage water-block, and features an aluminum back-plate to cool memory chips on the reverse side of the PCB. The card features 6 GB of total memory, 3 GB per GPU.

On the demo system, the full-coverage block was seen connected to a conventional-looking liquid-cooling loop, and not something closed-loop/AIO. Coolant tubes from the card run to a conventional-looking reservoir, a 240 x 120 mm radiator, and a pump that occupies a 5.25-inch drive bay, and features a pressure gauge. We're not sure if the Sapphire Atomic-branded FB blocks for the CPU and chipset are part of the package, but Sapphire has, in the past, given CPU blocks with its Atomic-branded cards. This is one card to watch out for.
