The preparation for the announcement of AMD graphical solutions with directX 11 support confused many. Major information was dedicated to high end video chips, which we usually call RV870, and in the photographs of real models, for some reason, appeared a product with a step below, which can become the successor Of radeon HD 4770.
In other words, until now there was no final clarity, in which sequence will appear AMD graphical solutions , which DirectX 11 support. At the end of September will be presented one chip product with directX 11 support , which in retail will cost more than $300.
Nearer to December to public will be proposed more accessible video card with directX 11 support. Their retail cost will be arranged in region $200. If we consider that NVIDIA will inject DirectX 11 from the elder one chip solutions only in the fourth quarter this year, then the new API will cost more than $300 for video card on base of RV870. Besides the support to the sequential version directX 11, this chip will bring an increase in the speed level ; therefore, the prices level in some degree will be justified.
Products on base of RV870 chip will obtain the names radeon HD 5870 and Radeon HD 5850, and also 1 Gb GDDR-5 memory. For the work with elder video card will be required a power unit with power not less than 500 W with two six-pin power connector, plus not less than 1 Gb memory. The crossFire of two video card will require already 600 W. According to unofficial data , the announcement of video card series radeon HD 5800 is assigned on 22 September.
