There might once have been uncertainty as to whether or not Advanced Micro Devices would ever actually release a dual-GPU Radeon HD 7000 graphics card, but there is no doubt left now.
The estimated arrival date, for one, is no longer estimated. It is a sure thing: April 24, 2014, which means Tuesday, four days after the time of this article's writing. We can also finally relay the exact specifications of the adapter, thanks to ChinaDIY website. The information fits previous leaks, like the eBay auction and the report about the release day earlier this week. The Radeon HD 7990 used to be called New Zealand, back in 2012, but then AMD decided not to actually release a reference adapter. Having reconsidered this year, it chose to name it “Malta” instead, and gave it two Tahiti XT GPUs, each with a clock speed of 1 GHz, 2048 Stream processors and a memory interface of 384 bits.
The chips operate in tandem thanks to an on-board implementation of CrossFireX multi-GPU technology. And since each chip has 3 GB of GDDR5 memory backing it up, everything boils down to 4096 Stream processors, 6 GB of GDDR5 at 6 GHz clock speed, 64 Raster operating units, 2 Prim /Clock, 256 Texture mapping units, and a total memory interface of 768 bits. Thus, the bandwidth is of 576.0 GB/s and the peak compute performance is of 8.2 TERAFLOPS. As for the cooler, it is a dual-slot contraption with three fans of 92 mm in diameter, with turbine design and internal vapor chamber heatsinks. One chamber is placed on each core, and copper heatpipes link them together. The cost of the newcomer is bound to be of over $1,000 / 1,000 EUR, like that of the NVIDIA GeForce GTX 690.
It should be noted, however, that while AMD will formally introduce the product next week, availability won't ramp up immediately. The time in between can be spent finding monitors to make use of the Dual Link DVI and 4 mini Displayports (Eyefinity supported, naturally).
