A Chinese website has posted a naked picture of AMD's upcoming Radeon HD 7990 graphics card. It's a partial snapshot that shows one of the two GPUs AMD crammed onto this pixel pushing monster, which supposedly consists of a pair of Tahiti XT graphics cores, the same as found on AMD's Radeon HD 7970 videocard. If the information is correct, the card will launch in April, after Nvidia's Kepler rolls into town.
As detailed in the post over at INPAI.com.cn, the Radeon HD 7990 sports a pair of 28nm Tahiti XT GPUs, each with 2,048 stream processors, 128 texture units, 32 raster units, and 3GB of GDDR5 memory on a 384-bit bus. The GPUs are clocked at 850MHz and the memory races along at 1,250MHz, or 5GHz effective.
For the sake of comparison, a single-GPU 7970 card features a 925MHz core clockspeed and 1,375MHz memory clockspeed (5.5GHz effective), and is priced at $550.
