NVIDIA GeForce GTX 770 - More Than Meets the Eye
By Michael Low & Kenny Yeo - 30 May 2013

Overclocking, Temperature and Power Consumption


The over-volting utility from EVGA Precision (version 4.2.0) didn't work for the NVIDIA GTX 770 card but we managed to overclock the GK104 chip to 1141MHz for its base clock; while for its video memory, we managed to push its operating frequency to a high of 7142MHz DDR with an offset of 200MHz.




The GeForce GTX 770 recorded a maximum sustained GPU temperature reading of 71 degrees Celsius, just a mere two degrees Celsius more than the GeForce GTX 680. It was a whopping 12 degrees Celsius cooler than the Radeon HD 7970 GHz. We have long lamented that the Radeon HD 7970’s cooler was insufficient for its GPU. More so the racket it makes compared to the new GeForce 780 and 770 graphics cards.


Power Consumption

Idle power reading of the GeForce GTX 770 was slightly lower than that of the GeForce GTX 680 and Radeon HD 7970 GHz Edition. At load, it maximum power draw was recorded to be 380W, 15% more than the NVIDIA GeForce GTX 680. Clearly, the extra performance has had a negative effect on both thermal and power characteristics. Nevertheless, its figure was considerably lower than that of the Radeon HD 7970 GHz Edition at 439W.
