The Windows 10 April update brought a lot of new features. One of the little-known features is a new power plan called ultimate performance mode. According to Microsoft, this mode decreases the micro-latency between the OS and the hardware. Exactly what that means, I’m not too sure. However, this mode is more than just made up fluff.
I ran a couple of benchmarks between using the default balanced mode on my PC and the ultimate performance mode. In Cinebench, I scored 816 with balanced and 848 with ultimate performance mode. In user bench, my overall score increased in ultimate performance mode. Most notable were the increased in random read and write speeds for my SSD.
