About two weeks ago, AMD had renewed its range of entry level cards with the number 7700, and now offers the 7800 which is roughly twice as powerful. Both have a 256-bit bus with GDDR5 memory 4.8GHz. The 7850 has a 860MHz processor and 2GB of RAM, while the 7870 Edition GHz processor 1GHz. Both share 11.1 and OpenGL graphics DirectiX 4, High Speed HDMI and mini DisplayPort.
The reduced energy consumption was not the main consideration, as both AMD Powertune enjoy the feature, designed to reduce energy expenditure when the GPU is not used. The cost of both is carefully designed to place themselves into the competing Nvidia cards, and while the 7850 costs $ 250 $ 7,870 350. In this price range are likely to be the many big and small PC assemblers to take advantage of two GPUs to build the best PC exaggerated (or even Mac, if Apple will).
The launch will come in a couple of weeks, since AMD has chosen to give notice in advance to prepare partners (and wallets) to the great forum of information that will be in Hanover, CeBIT.
