Nvidia GK104 To Introduce Dynamic Clock Adjustment

As the launch of Nvidia’s Kepler GK104-based card comes closer, more and more details are being revealed about the card. GK104 will introduce something called Dynamic Clock Adjustment which works much like Intel’s Turbo Boost or AMD’s Turbo core, adjusting the core speed above and below the base-line 705 MHz. While decreasing the speed is nothing new with most cards, an automatic overclock during high load is.

The number of power plans is reported to be “in the dozens” and will switch depending on temperature and load. While the core speed will be able to deviate both above and below the base-line speed, the shader clocks will operate independently as opposed to being linked as with current cards – current cards have shader domain clocks which are locked to twice that of the core speed. The shader clocks on GK104 will be able to scale down, but will not pass the base-line speed of 1,411 MHz which will be attained at full load. Source — VR-Zone
