SteamOS vs Windows 8 Benchmark Results Are Here
A comparison between SteamOS and Windows isn’t really fair since Windows has so many background apps and services running when playing games while SteamOS is open source and tries to mimick living room experience and counter the firmwares of PS4 and Xbox One in terms of ease and performance.
Still, a guy over at Egee.io decided to do it any way with a multitude of benchmark softwares and a few games all running at 1080p.
The benchmarking was done on SteamOS 2.0 (OpenGL) and Windows 8, not the best Windows to be doing the testing on and its highly likely that it impacted the results a bit.
Even then judging by the results, Windows 8 has a very slight edge over SteamOS when it comes to Furmark and Julia FP64 benchmarks, outperforming SteamOS by 2-3 frames. This gap becomes bigger when using the Marble and Cylinder Grid test when testing out MadShader tool.
Windows 8 continues to outperform SteamOS even in other tests including Uningine Valley and Metro 2033 Redux game however what’s interesting is the fact that Valve’s very own game, Counter Strike Source at Very High settings performs better on SteamOS and that too by a margin of average 5 frames per second.
The full details of benchmark results and the system used for testing can be seen here.
