"Given how fiercely the latest open-source AMD Linux driver
code is running now up against NVIDIA's long-standing flagship Linux GPU
driver, you might be curious how well that driver stacks up against the
Radeon Software driver on Windows? Well, you are in luck as here are
some fresh benchmarks of the Radeon RX 580 and RX Vega 64 as well as the
GeForce GTX 1060 and GTX 1080 Ti while being tested both under Microsoft
Windows 10 Pro x64 and Ubuntu 16.04 LTS while using the latest
AMD/NVIDIA drivers on each platform."
