The clock speed of AMD’s upcoming flagship with two gpus, the Radeon HD 7990, 850MHz amounts, claims a Chinese site. That is 75MHz slower than the Radeon HD 7970, which has a single Tahiti XT gpu.
As usual in the past few years AMD with a dual-gpu card, then the most powerful card in his range. According to rumours that should be next month happen. There are two Tahiti XT gpus on the card. This chip is also at the heart of the Radeon HD 7970. With the HD 7990 is the clock speed is lowered from 925 to 850MHz, claims Chinese site Inpai. Also the memory speed has been adjusted downward, from 1375 to 1250MHz or effective from 5500 to 5000MHz.
For the rest, would be the specifications of the gpu remain the same; the two chips have reportedly each with 2048 shaders, 128 texture units and 32 rops. In addition, the Radeon HD 7990 effectively 3GB of gddr5.
At the end of this month, the GeForce GTX 680 from Nvidia and expected that to have been which is faster than the HD 7970. Nvidia will, in all likelihood, with a dual-gpu card. The question is, how much time will pass between the release of Nvidia’s and AMD’s cards with two gpu’s and what the price and performance difference will be.
