3DMark Time Spy
Rendered at a 2,560x1,440 QHD resolution and making use of DX12 technologies such as asynchronous compute, explicit multi-adapter and multi-threading, Time Spy is a forward-looking 3DMark benchmark that hints at GPU potential in various upcoming games.
There's a little more GFLOPS horsepower on the GTX 1080 Ti, and appreciating this benchmark is more compute bound, the GTX 1080 Ti wins out.
However, what's disturbing is the stability test. The Titan X has a fair bit of variability while the GTX 1080 Ti still fails the 97 per cent threshold.
Why? Both cards start off boosting up to 1,700MHz but then scale back to 1,500MHz on Titan X and 1,600MHz on GTX 1080 Ti once the temperature hits 83°C. In other words, the cooling holds the underlying GPU back. We'll cover more of this in the temperature section.
