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 with a phoronix-test-suite profile available and they all use the Source engine. Hopefully the Phoronix Test Suite’s author Michael Larabel will provide us more profiles in the future, games with different engines.
AMD Radeon HD 7950 using kernel 3.15-rc4 + PTE patches (VRAM page table entry compression) + hyperz (R600_DEBUG=hyperz). I’m also using libdrm git, xf86-video-ati git, llvm 3.5 git, mesa git (OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.0-devel (git-cf93f86)) and Keith Packard’s xorg-server glamor-server branch (1.16.0 RC 2). Catalyst version is 14.4 (kernel 3.14.3, xorg-server 1.15.1).
Radeonsi is 21% faster than Catalyst with Half-Life 2: Lost Coast.
Radeonsi is 3% faster than Catalyst with Team Fortress 2.
Radeonsi runs at 81% of Catalyst with Portal.
