Windows 7 vs. Windows 8.1 mini-performance analysis

BabelTechReviews has made the move to Windows 8.1 because of what appears to be better support for 4K resolution when we upgraded to a Monoprice Crystal Pro K display.  Originally we had some issues switching resolutions in-game with Windows 7 that were completely resolved by upgrading to Windows 8.1 with a clean install.

Windows 8.1 is still a bit of a hybrid operating system, partly aimed at the desktop and also at the more casual, mobile user.  Although there is no Start button, Windows 8.1 has become more tolerable for desktop productivity and we will continue to benchmark with it until Windows 10 is released and stable for benching.

Evolve 2015-02-16 19-10-13-78The first thing we want to see is if the performance is similar between Windows 7 and Windows 8.1.  We reran our 30-game benchmark suite with the GTX 980 with WHQL driver 347.52.  Our testing platform is Windows 7 64-bit, using an Intel Core i7-4790K at 4.00GHz with turbo to 4.4GHz for all cores, ASUS’ Z97E motherboard, and 16GB of Kingston “Beast” HyperX RAM at 2133MHz. The only difference now is that we are using Windows 8.1 at 1920×1080 and at 2560×1600.

Here is our complete test configuration:

There are no surprises.  Windows 8.1 has an extra abstraction layer and the performance penalty is about 1-2% generally in our 30 game benchmark suite. However, there are a very small handful of games that appear to actually run better on Windows 8.1.

Conclusion

attilaSo far, we would not necessarily recommend upgrading to Windows 8.1 if you are running Windows 7.  However, there are some advantages to using the latest Windows operating system and one of them appears to be better 4K gaming.

Stay tuned, next up we are benching for a CrossFire versus SLI Showdown featuring GTX 980 SLI versus R9 290X CrossFire at up to 4K
