GeForce GTX 690 Review: Dual NVIDIA GK104 GPUs

Overclocking the GeForce GTX 690

NVIDIA claims that the GeForce GTX 690 had overclocking plenty of headroom for overclocking thanks to its beefy 10-phase power delivery, and somewhat conservative stock frequencies, so we fired up of EVGA’s excellent Precision performance tuning utility, which already supports the GeForce GTX 690, to see just how much additional performance we could wring from the card. We also installed a slick GeForce GTX 690 skin that matches the color scheme of the card.

During some conversations we had with a few representatives from NVIDIA in the past, we were told that most GK1-4 GPUs would likely be able to hit frequencies around 1.2GHz, with stock cooling. Our testing proved that to be true.

By cranking up the power target by 35% and increasing the GPU Clock Offset by 150MHz, our GeForce GTX 690 would consistently boost to about 1.215GHz with perfect stability and zero visual artifacts. We were also able to crank the memory clock up by another 113MHz for an additional performance boost.

While we had the card overclocked, we re-ran a couple of high resolution tests, and when all was said and done we were able to increase performance considerably. Metro 2033 shows a 7.2% improvement in framerate while overclocked, and performance in Alien vs. Predator--which is mostly bound by memory bandwidth--increased by 7.6%.
