Before GPU Boost, GPUs were held back by synthetic benchmarks that pushed power usage to the limit, far beyond the levels typically seen when playing games. This ‘worst case scenario’ forced us to throttle GPUs, leaving spare performance on the table. GPU Boost resolves this problem by continuously monitoring power usage and temperatures, enabling the GPU to use every last ounce of performance without exceeding safety or comfort limits.
With the software and hardware innovations brought to the table by Kepler GTX 600 Series GPUs in 2012, every application and game runs at a guaranteed, minimum Base Clock speed. If there’s extra power available, a Boost Clock is enabled increasing clock speeds until the graphics card hits its predetermined Power Target (170 Watts on the GTX 680, for example). This dynamic clock speed adjustment is controlled by GPU Boost 1.0, which monitors a raft of data and makes real-time changes to speeds and voltages several times per second, maximizing performance in each and every application.
But it doesn’t end here. NVIDIA’s engineers have improved on GPU Boost 1.0 and have just released GPU Boost 2.0 for GTX 700 series and newer graphics cards cards.
