AMD Linux Graphics Driver To Switch To More Aggressive Power Heuristics By Default

Key info, this relates to discrete cards only, not integrated graphics:

Since Linux lacks the infrastructure for properly and reliably indicating if a full-screen 3D game is running versus another application, this change will just use the full-screen 3D power profile at boot time by default. It's better in the name of performance but with more aggressive ramping of the core/memory clock frequencies it can come with an increase to power use by default.
