Today, AMD would officially announce their latest Radeon HD 7990 Dual-Chip graphics card codenamed "Malta" which combines two Tahiti cores to offer blazing fast gaming performance. Announced almost a year ago, the Radeon 7990 was previously codenamed "New Zealand" and it did arrive however only in custom built boards by AIB partners of AMD.
AMD Radeon HD 7990 "Malta" - Retaking the Performance Crown
A year later, AMD has finally launched their Radeon HD 7990, featuring dual Tahiti XT (HD 7970) cores featuringa total of 8.6 Billiontransistors, 4096 Stream processors, 2 Prim /Clock, 256 Texture mapping units and 64 Raster operating units. The Tahiti XT core is clocked at 1000 MHz or 1 GHz. The card features an impressive 6GB GDDR5 memory that operates along a 384-bit x2 memoryinterface and is clocked at 6.0 GB/s effective frequency. The memorypumpouts an impressive 576.0 GB/s bandwidth. The Radeon 7990 has a peak compute performance of 8.2 TFlops.
AMD’s Radeon HD 7990 is assembled using a dual-slot cooling solution which features triple fansetchedon the shroud. These 92mm fans are part of theturbine cooling design which provides enhanced cooling performance to the internal vapor chamber heatsinks equipped on each core and fused together using copper heatpipes. Power is supplied through Dual 8-Pin connectors, a massive improvement over the Triple 8-Pin connectors over the custom boards from AIB partners which would pit the rated TDP around 375W. Even with such an improvement, the card barely delivers the same amount ofefficiencyas its competitor - the GeForce GTX 690. NVIDIA's Kepler GK104 architecture has the upper hand in this case while the Radeon HD 7990 trumps it in pure computing performance

The card features DirectX 11.1, Open CL, Open GL 5.1, AMD Eyefinity and AMD Zero core technology support. The retail price of the card is set at $999 which is similar to the NVIDIA GeForce GTX 690 and the recently launched GeForce GTX Titan.
To spice up the value of their $999 mammoth, AMD would be bundling the card would their entire Never Settleportfoliowhich includes the following games:
Far Cry 3Far Cry 3: Blood DragonTomb RaiderBioshock InfiniteCrysis 3Dues EX: Human RevolutionHitman: AbsolutionSleeping Dogs
Now that's some tremendous value that amounts to around $450 US for the games alone.
