AMD’s plans to keep on making new Southern Islands graphics cards have resulted in rumors of Radeon HD 7990, HD 7790 and HD 7730 models. While these offerings are still some time away AMD has released some of the Radeon HD 7790 specs at CeBIT 2013 in Germany.
According to this preliminary information the future Radeon HD 7790 will have 896 stream processors and will be based on a GPU known as Bonaire. This GPU will be made on 28 nm tech process and will support DirectX 11.1 and OpenGL 4.3. Clock speeds and memory sizes are unknown but AMD expects the card to be around 10 per cent slower than the Radeon HD 7850. As to pricing the card is expected to sell for around EUR 135 which is comparable to the GeForce GTX 650 Ti.
The AMD Radeon HD 7790 will be an interesting product as it will be close to HD 7850 performance-wise while the card will cost the same as the Radeon HD 7770. The official release is expected in April 2013.
Furthermore AMD hinted it has working samples of the dual-GPU Radeon HD 7990 video card although such samples were not demonstrated at CeBIT 2013. AMD will release this product in H2 2013.
