The current generation AMD GPU series collectivelly known as "Southern Islands" were released over a year ago, with the beginning of its rollout in January 2012. Sixteen months later, the Radeon HD 7000 series is still very much relevant, as AMD continues to release new models under the same GPU family.
Although it's been over a year since AMD launched the Radeon HD 7970, we are just getting an official dual-GPU version. The Radeon HD 7990 takes a pair of 7970 GPUs with overclocked cores and memory, packing 8.2 TFLOPS computer power, 6GB GDDR5 and an upgraded PEX bridge to connect the two GPUs.
AMD has reportedly decided to push back the launch of the Radeon HD 7950 until early February. According to the Guru of 3D, AMD made the decision to avoid another paper launch and have the card available on the market when it actually launches.
