It appears that AMD / ATI is already finalizing its new graphical kernel, RV790, and we will soon see the first card on its base. According to the Singaporean Portal VR-Zone, in April this year, the American company returns to market the card Radeon HD 4890. However, according to data from several sources that it is precisely on Radeon HD 4970, but according to the VR-Zone, this information had nothing to do with reality.
However, this does not change the crux of the matter, as well as the fact there is that AMD / ATI have already prepared a response GeForce GTX 285, and the graphics engine is quite powerful. According to recent data, the engineering sample of Radeon HD 4890 operates at a frequency of 850 MHz and uses a video GDDR5. The frequency of VRAM at 975 MHz, and the graphical kernel operating voltage - 1.3 V. For comparison, Radeon HD 4870 (RV770 - photo) A graphic core and GDDR5 graphics memory of 750 MHz and 900 MHz respectively. If you believe AMD / ATI, Radeon HD 4890 is 20% faster than its predecessor, Radeon HD 4870 and will compete with the GeForce 285 GTX.
The estimated cost of graphics cards based on the Radeon HD 4890 varies in the range of 199-249 dollars.
