The real TL;DR is no. They are about equal.
Ashes of the Singularity is a game AMD had a big hand in making. There are driver level optimizations the studio paid for. Furthermore the game leverages D3D12's Async Compute which Pascal Architecture can't handle as well as GCN.
That being said in non-AMD sponsored games they two set ups in question (RX480 CFire vs GTX1080) do manage to stay within step of one another [1].
The real issue becomes overclocking and crossfire.
The GTX1080 has a much higher overclock threshold then RX480 (currently this may change as board partners make custome PCB's). So if you start fiddling with power levels this comparison breaks down.
Also crossfire/SLI is to a degree Russian Roulette. Studio's have to opt-in to supporting it, and sometimes don't. Leaving you only with a single card. Also very weird bugs can sometimes crop up. Some people have no issue with this, some have huge issues. YMMV.
The main thing I'm trying to express is when looking into hardware reviews CPU/GPU's more information from more sources is always better. And all sources/chips aren't equal.

- rdudek 10y agoAsync Compute is a big mess for nVidia right now. Latest trouble is Total War: Warhammer game. They released dx12 support for it and nVidia cards are losing 10fps+ while AMD cards are gaining 30%+ in performance. Also reason why Ark Survival Evolved is holding off dx12 release because of nVidia ...
- jsheard 10y agoIt's really difficult to draw conclusions from DX12 benchmarks at the moment. The problem is that DX12 shifts most of the responsibility for architecture-specific optimizations (and avoiding pathological cases) from the driver to the application. So although you could draw the conclusion that Nvidia are struggling with DX12 due to their Total Warhammer performance, it's just as easily explained by Nvidias veteran DX11 driver team being better at tuning for Nvidia hardware than a game studio who partnered with AMD during development.
- dreamsofdragons 10y agoYou mean the game that AMD is giving away for free with it's cards right now, to showcase it's cards, which has been optimized completely for AMD cards is outperforming nVidia cards? I'm shocked.
