Nvidia’s Control Panel settings:
We used MSI’s Afterburner to set the Power and Temperature targets to their maximum for all benchmark runs.
There are two methods of calculating percentages. One is the “Percentage Difference” that we originally used to compare the GTX 1080 versus the TITAN X, and the other is “Percentage Change” which we are using now to show the improvements of the overclocked GTX 1080 Ti over the stock GTX 1080 Ti, and the improvements of the overclocked TITAN X over the stock TITAN X.
For the percentage change, we mean the change in framerates between the stock GTX 1080 and the overclocked GTX 1080 Ti, or the change in framerates between the stock and the overclocked TITAN X, divided by the absolute value of the original value in fps, multiplied by 100.
Percentage change may be expressed by the algebraic formula: ( ΔV / |V1| ) * 100 = ((V2 – V1) / |V1|) * 100
Let’s get to our overclocking methods, and finally to the 25-game overclocked results.
