Radeonsi with si scheduler humiliates Catalyst in all tests

Following my last article I decided to test Axel Davy’s si scheduler and run the very same OpenGL4+ tests with both radeonsi+si scheduler and Catalyst. The si scheduler is such a huge performance boost! Not only it is faster, but now radeonsi is faster than Catalyst in *all* tests, sometimes by a wide margin! Catalyst […]

Radeonsi vs AMD Catalyst vs NVIDIA proprietary on GL4+ workloads


Radeonsi is faster than Catalyst with Steam games

As I said in my previous post radeonsi is becoming faster than Catalyst in several scenarios. Some peoples on phoronix didn’t think it was actually possible and blamed “old games”. So I decided to benchmark Steam games, in particular Half-Life 2: Lost Coast, Team Fortress 2 and Portal. Unfortunately these are the only Steam games […]
