GeForce GTX 680 Clocks Explained

Published: Mar 19th 2012, 14:38 GMT

Gigabyte GTX 680 2GB already arrive at my shop! :)Lots of rumors were spreaded out since first leaks surfaced. But since the card is finding new owners as we speak, we have more detailed information now. Owner of GTX 680 has explained on forums why GPU-Z shows different clocks.

There are three profiles of core clock for GeForce GTX 680. First is the “idle clock” set at 706 MHz. Full load upscales it to 1006 MHz, but there is also third clock – Turbo Boost, which can be set as default full load clock through NVIDIA Control Panel.

Memory clock is set to 1502 MHz, which is 6 GHz effectively. Shaders are clocked twice as fast as core clock. Review which was posted by HKEPC suggests this card can be easily overclocked to 1150 MHz for core and 1800 MHz for memory.

This is how clocks settings look:
