An anonymous tipster left an interesting picture on our doorsteps. It shows a pair of Radeon HD 7990 "Malta" reference-design graphics cards chugging along inside an enthusiast PC. AMD surprised us late last month, when it showed off a reference-design Radeon HD 7990 dual-GPU graphics card, at the Game Developers' Conference (GDC) event. The cards in this new picture appear to be identical to the one AMD showed. The "Radeon" embossing appears pretty clear on both cards, so one can't mistake them for FirePro S10000. Bearing a new internal codename "Malta," compared to last year's various dual-HD 7970 contraptions that were codenamed "New Zealand," the new Radeon HD 7990 is being designed to be far more energy efficient, and quiet. While the various "New Zealand" cards often featured three 8-pin PCIe power connectors and triple-slot cooling solutions, "Malta" makes do with just two 8-pin power connectors, and a dual-slot cooler. We've been talking to a lot of reliable sources in the industry, and nobody has any clue about a tentative launch date.
