The Team Fortress 2 benchmarks occurred while having to switch out many different GPUs for an upcoming Linux graphics card review of the low-end GeForce GT 610 and in feeling like running some extra Linux benchmarks over my birthday. This GeForce GT 610 review was happening from an AMD FX-8350 "Vishera" test-bed, which is more than adequate to pair with low-end graphics cards.
In the NVIDIA Linux benchmarks from Friday of Team Fortress 2, some wondered whether the FX-8350 even though it's one of AMD's high-end desktop processors whether that could be a bottleneck with some of the higher-end GeForce graphics cards. After carrying out the Radeon GPU tests on Saturday night, this does indeed appear to be the case, even at 2560 x 1600.
So while the AMD FX-8350 is lowering the numbers, by this time I had already ran some TF2 Source Engine benchmarks on the Radeon HD 5450, HD 5750, HD 5830, HD 6570, HD 6770, HD 6870, HD 7850, HD 7950, and R9 270X. All nine graphics cards were tested with Ubuntu 13.10 on the Catalyst 13.11 Beta 6 proprietary GPU driver.
I'm putting out these numbers today simply for reference purposes and you can run your own comparison by executing phoronix-test-suite benchmark 1311093-SO-AMDRADEON18.
Fortunately, NVIDIA has decided to send over some new ultra high-end GPUs for Linux testing at Phoronix. Those new GPUs will be coming soon and that testing will be from one of the more powerful Intel Core i7 4770K Haswell systems or Ivy Bridge Extreme Linux systems. At the time of running those new high-end Linux GPU benchmarks, the Team Fortress 2 benchmarks will be re-run and should be more interesting. For those that have been making other Steam-based game test requests, see my original comments why it isn't reliable benchmarking through Steam. Additionally, for the recent Metro: Last Light test requests, the built-in benchmark mode that was present in the Windows version doesn't even seem to be available on Linux.
