Graphics card Power Color, MSI, Sapphire Technology and others have been released or are planning to submit custom design of this map, which speeds close 1000MHz mark. This is a significant increase in performance, given that the standard is RV790 GPU clock of 850MHz. But increasing the clock speeds will be the price of the card, which is currently estimated at about U.S. $ 249 for the basic model.

AMD's Radeon RV790 GPU is designed with 800 stream processors, 40 texture units 16 to make back-goal and a 256-bit memory bus. The map of the 55nm GPU with GDDR5 memory is linked to an optimal level of performance with support for increased clock speeds, when the card is presented with its own cooling solution.

Power Color has its latest Radeon HD 4890, which is equipped with a PCS + cooling and a GPU clock of 950MHz. But the next card from Sapphire provides users with the January 1 GHz GPU, directly from the box, with the launch of the company's next-generation Atom-card.
