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.

Popping up over the weekend is a somewhat blurry photo (cleaned up as best we could) of a completely naked dual-GPU prototype of AMD's Radeon HD 6870. The full frontal snapshot shows two Barts GPUs positioned in the middle of a long slab of PCB. Each GPU boasts 1,120 stream processors for a total of 2.240, and each with its own 1GB of GDDR5 memory, also visible in the picture.

We heard back in April that Nvidia would be releasing its dual-GPU GeForce GTX 590 videocard sometime this month. We're now 10 days into March and the only modern-generation dual-GPU videocard on the market is AMD's recently released Radeon HD 6990. That won't be the case for long. According to reports, Nvidia will drop its new flagship part March 22nd, or just under two weeks from today.

A Turkish website posted a ton of information on AMD's upcoming dual-GPU Radeon HD 6990 graphics, along with a bevy of official slides, or at least really good Photoshops (not likely). Code named Antilles, the 6990 is slated to launch March 8 and will take its position as AMD's flagship videocard, Donanimhaber.com says. That puts the launch nearly a week ahead of Nvidia's dual-GPU GeForce GTX 590, running contrary to previous reports that AMD would wait until after Nvidia outed its card.
