With the release of the new operating system Windows Seven Microsoft has also released a new library for DirectX11 graphics, incorporating many new and inevitably need of new graphics cards compatible with the new API.

AMD at the time of the launch of Windows Vista and new libraries DX10 then found himself in extremely late with the release of the first solution compatible with the new API 6mesi with us about the party that NVIDIA was already under way with the solutions based on G80.

This delay abysmal, partly due to the mess created by the acquisition of ATI by AMD, dubbed the R600 GPU and HD2900 cards as a flop, since even performance were not comparable to the top solutions range NVIDIA 8800GTX and GTS.

In subsequent years, AMD has rolled up his sleeves and based on R600 architecture continued development by accelerating the timing as much as possible to recover the time gap with rival. AMD to recover the performance gap has also invested heavily in the adoption of new technologies on their boards as several types of bus controller for the ram and the adoption of the first and later the GDDR4 GDDR5 to offer innovations that lead to a reduction of the final price But while increasing performance.

Just over a year ago there was the coupling of ATI against NVIDIA, the new RV770 GPU arrival with one week late compared to NVIDIA's GT200 solution, although as I remember it the anabolic RV770 RV790 still managed to close the performance gap with the top single GPU solutions from NVIDIA.
