GTX 680 first graphics cards to hit the Kepler market as always the top of the range. These include 1536 graphics core running at 1006 MHz, a speed that can automatically go up to 1058 MHz through the functionality of automatic overclocking the GPU Boost. The GPU boost constantly analyzes various factors such as temperature and energy. If there is room for maneuver increases the processing speed automatically without any user intervention.
The graphic Kepler also include 2 GB of GDDR5 RAM with 256-bit bandwidth and 6 Gbps capacity and compatibility with PCIE 3.0
Kepler is an improved architecture compared to the previous generation with 3.5 billion transistors. According to Nvidia, much more power than the generation of graphics cards to replace. This increased power results in a complete redesign of the graphics. For example, a GTX 580 had groups each processing core 32 and a controller. By comparison, each group of the GTX 680 has 192 processors, six times more than the previous generation. Eight of these groups are the nuclei that make 1536 such a GTX 680.
Besides the hardware, the new GTX 680 support new antialiasing modes. According to Nvidia, the TXAA provides eight times quality of MSAA and costing the same in terms of performance of the MSAA 4x.
Finally, we Adaptive VSync, which allows us to enable VSync without the huge losses associated performance.
The average sale price suggested by Nvidia for the GTX 680 is 419 euros, excluding VAT. With VAT, the price should be € 520 in Portugal. However, we must bear in mind that these are the prices suggested by Nvidia and not by the partners who actually sell the graphics cards.
