Overclocked Radeon HD 4890 on their way to the market

Even before the official release of AMD's latest graphics processor, the RV790-based Radeon HD 4890 is expected to be an important sexton of the computer and gaming enthusiasts with the means to their computer visual performance by tweaking the GPU. When released AMD also forged the overclocking ability of the Radeon card, which said that it can deliver clock speeds of 1 GHz, a figure that is somewhat unique in the world of desktop video cards.

Following the introduction of the 55nm RV790, there were reports that AMD felt there was no need for a partner for the factory overclocked versions of Radeon cards, especially since the dual GPU Radeon HD 4870 X2 is a choice for overclocking of enthusiasts and high-end players. However, it appears that some AMD has already introduced HD 4890 card is equipped with a factory overclocked GPU.

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.
