The GTX 1080 Ti vs. The TITAN XP Overclocking Showdown

Overclocking

Overclocking with MSI’s Afterburner

Afterburner is a free MSI utility which offers these very useful features:

  • Overclocking tools for Nvidia and AMD cards
  • Hardware monitoring
  • Overvoltaging controls (which are not supported yet for the GTX 1080 Ti nor the TITAN X)
  • Triple Overvoltage which provides precise control of the Core, Memory and PLL voltages (unsupported for TITAN X/GTX 1080 Ti)
  • Custom Fan profiles
  • FPS in-game counter for DX11/OpenGL games
  • 64-bit support/Custom Skins/Multi-language support/stability testing/video capture/mobile apps

Make sure to check out our GTX 1060 overclocking evaluation.

The TITAN X OC

A 160MHz offset turned out to be the highest stable core overclock that we could achieve with all of our games with the TITAN X.  Boost reaches 1949MHz and it stays steady through all of our benching with the fan at 100%. The fan is loud at this point, but it is more of a “whoosh” of air which is not an irritating whine and it keeps our GPU under 70C even on a hot day.  We continue to benchmark at 100% fan because we want to have the most consistent results – something that overclockers putting the TITAN X under watercooling will easily achieve.

Pascal likes low core temperatures to achieve its maximum overclock but we were unable to cool our test room below 80F on our record-setting warm Southern California Winter day.
100 fan160mhz mem-200mhzWe settled on a 200MHz memory clock offset to reach 5200MHz (10400MHz) and our highest performance in games.  Our final TITAN X overclock of an additional 160MHz to the core and 200MHz to the memory gave us a steady 1949MHz core and 5200MHz memory.

GTX 1080 Ti Overclocking

We found overclocking with the GTX 1080 Ti to be very similar to overclocking the TITAN X with the exception that the faster vRAM that the Ti uses is much more overclockable.  We were able to add 150MHz to the core and a 500MHz offset to the memory with complete stability through all of our testing on very hot days with the result that we reached a steady 1999MHz core and 6000MHz (12000MHz) memory clocks.
The GTX 1080 Ti’s fan profile is similar to the TITAN X’es and the GPU generally stayed under 70C with the fan at 100% and the noise level is similar to the TITAN X noise level.
All of our games were benchmarked at these respective overclocks with complete stability.
Let’s check the performance results of 25 games with our games at stock TITAN X and GTX 1080 Ti speeds (Power/Temp Limits at maximum) compared with our highest stable overclocks.

    Your witcher 3 results for Titan X at 1440p seem off. The OC number is lower than stock yet you list it as an increase.

      Thank-you. You are correct. The OC number was switched with the stock. I made a note of it under the chart for now, and I’ll replace the chart after rechecking it.

    Interestingly enough, I am able to attain 5900Mhz on my Titan X’s GDDR5X memory and 1986Mhz on the GPU (card is custom watercooled). So close in fact that for me, buying a GTX1080Ti is pointless. Current Titan X owners can say, “meh” and pass on the GTX1080Ti. However, for those that own a GTX1080 or less and plan to game at 1440P and higher resolutions, the GTX1080Ti is a must have if you want the best bang for the buck and want to be able to use the higher in-game graphics settings 😉

    My Titan XP gets around 2000mhz 95% of the time, only some games it has to back off to around 1950. I use it for Blender and it is a beast.

  • YUGWMB

    Can you SLI the Titan XP & 1080ti?

    • apoppin

      Not with each other. The TITAN XP can be SLI’d with another XP just as the Ti needs to be paired with another Ti.

      The only way you can use the two of these cards together would be in specific DX12 games where the dev specifically codes it to use mGPU.
