AMD Radeon R9 285 Linux GPU Scaling Performance

RADEON --
For those wondering about the maximum resolution they can run given OpenGL workloads at with the AMD Radeon R9 285 "Tonga", a new ~$250 USD graphics card, here's some Linux GPU scaling benchmarks with the Catalyst driver.

If you didn't see my review from Tuesday there's a complete review of the Radeon R9 285 Tonga under Linux as the first AMD GCN 1.2 GPU on the market using Catalyst -- since the open-source driver isn't yet compatible. Following that full 12-page review I ran some GPU scaling tests. If you're curious, here's those results.


The above mentioned setup was used for this round of testing. If you wish to see how your own system compares, install the Phoronix Test Suite on your Linux distribution then run phoronix-test-suite benchmark 1410152-LI-4KSCALING41. In this article the resolution scaling of the Radeon R9 285 on Ubuntu Linux is being looked at up to 4K UHD.


Counter-Strike: Global Offensive on Linux runs well except up to 4K where it starts to dip low.


OpenArena gradually degrades, but is certainly playable through 4K, given the state of this lightweight open-source game.


Tesseract really dipped off in its performance after 1080p.


Unigine Tropics is sub-60 FPS at 3840 x 2160 on Ubuntu Linux.


Unvanquished takes a big dive at 4K.
You can see all of these benchmarking results and many others via OpenBenchmarking.org.
