Intro

This overclocking showdown is the third of our Pascal GTX 1080 Ti series. After introducing it seven days ago, we compared it with the GTX 1080 and the TITAN X. The GTX 1080 Ti was generally 1/3rd faster than the GTX 1080 and about 1-5% faster than the TITAN X in our 25-game benchmark suite. Then we benchmarked those same 25 games with GTX 1080 Ti SLI and found it to be ridiculously fast when SLI scales well. Now we want to overclock the GTX 1080 Ti and also the TITAN X as far as we can to see how well they each scale.

Our testing platform is Windows 10 Home 64-bit, using an Intel Core i7-6700K at 4.00GHz which turbos all cores to 4.6GHz as set in the ASRock Z7170 motherboard’s BIOS, and 16GB of HyperX DDR4 at 3333MHz. The settings and hardware are identical except for the clocks being tested.

How well do the GTX 1080 Ti & TITAN X Overclock?

The TITAN X and the GTX 1080 Ti are both large 220W+ TDP chips which tend to overclock less than the smaller and lower-TDP GPUs of the Pascal family. We are going to look the performance of the stock and overclocked TITAN X compared with the stock GTX 1080 Ti as well as overclocked as far as it can go with up to 100% fan speeds using MSI’s latest beta version of Afterburner.

We are going to concentrate only on overclocking the GTX 1080 Ti and the TITAN X. AMD’s flagship, the Fury X, is slower than the GTX 1080 and in our ongoing tests, it has failed to win a single benchmark. Both the GTX 1080 Ti and TITAN X are in a class even higher than the GTX 1080, and AMD is pinning their hopes on their upcoming big chip, Vega.

Let’s check out the test configuration.
