3DMark Time Spy
Rendered at QHD or UHD resolutions and making use of DX12 technologies such as asynchronous compute, explicit multi-adapter and multi-threading, Time Spy is a modern 3DMark benchmark that hints at GPU potential in today's latest games.
Knowing that the PowerColor card ought to be faster solely due to its 100MHz boost clock advantage, it is reasonable to assume performance will be marginally higher. It's good to see the Red Devil put over 300 marks into the MBA card at UHD.
Run-to-run consistency is excellent thanks to that truly massive cooler.
