Before we get to the GTX 960 performance charts, let’s look at overclocking, power draw and temperatures.
Overclocking, Power Draw & Temperatures
Thanks in part to Maxwell’s power efficiency, the GeForce GTX 960 evidently has a lot of headroom for overclocking. The base clock frequency is 1126MHz, with a boost clock of 1178MHz. In Nvidia’s internal testing, GeForce GTX 960 engineering sample boards regularly hit 1450MHz or more without any temperature target, fan speed or voltage modifications.
Additionally, since the GeForce GTX 960 runs cool, some of Nvidia’s board partners including ASUS will allow the card to run silently with the GPU’s cooling fan completely shut off under certain gaming workloads. We have noticed 8 rpm during gaming although we never actually observed zero rpm.
Overclocking, Power Draw, Noise and Temperatures
Overclocking the GTX 960 is just as easy as overclocking Maxwell or Kepler with the same features. We were able to overclock further, adding +85MHz offset to the already overclocked ASUS GTX 960 core with complete stability, even though we did not adjust the voltage nor our fan profile. Temperatures were cool. Even in a warm room they *never* exceeded 60C and the video card’s twin fans were never heard over the case and CPU cooling fans.
With our particular sample of the ASUS GTX 960 OC, the base clock was 1317MHz and it would regularly boost to 1405MHz and stay there. That is +171MHz over reference clocks. The ASUS memory clocks are also set higher at 7200MHz, up 190MHz over the reference memory clocks. We used the excellent ASUS GPU Tweak Utility to set our overclocks.
Adding +85MHz to the core brought the peak boost up to 1495MHz and it stabilized there as the temperature never exceeded 60C. Overclocking the memory to 8000MHz(!) brought performance increases but no temperature rise and the fans never had to ramp up. Adding +100MHz to the core brought the peak boost up to 1505MHz but the overclock was unstable so we settled on a 85MHz offset together with memory at 8000MHz as our final stable overclock used in our testing
Let’s head to our performance charts.
