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.
Using the 19.9.1 driver, performance is marginally better than the Pulse card also from Sapphire. What's not in doubt is the excellent cooling ability of the massive heatsink, evidenced by a really solid Stress Test result.
