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 are clear hierarchies for GPUs. RX 580 is decent, GTX 1080 improves matters greatly, and jumping up to GTX 1080 Ti offers best-in-class numbers.
That monstrous cooler does a grand job of keeping the card's performance consistent, however.
