Phoronix published a review on the The AMD Radeon R9 Fury Is Currently A Disaster On Linux
A quote from the article:
When AMD announced the Radeon R9 Fury line-up powered by the "Fiji" GPU with High Bandwidth Memory, I was genuinely very excited to get my hands on this graphics card. The tech sounded great and offered up a lot of potential, and once finally finding an R9 Fury in stock, shelled out nearly $600 for this graphics card. Unfortunately though, thanks to the current state of the Catalyst Linux driver, the R9 Fury on Linux is a gigantic waste for OpenGL workloads. The R9 Fury results only exemplifies the hideous state of AMD's OpenGL support for their Catalyst Linux driver with a NVIDIA graphics card costing $200 less consistently delivering better gaming performance.The AMD Radeon R9 Fury Is Currently A Disaster On Linux @ Phoronix
