PC StatusOverall this PC is performing as expected (60th percentile). This means that out of 100 PCs with exactly the same components, 40 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith an average single core score, this CPU can handle browsing the web, email, video playback and the majority of general computing tasks including light gaming when coupled with an appropriate GPU. Finally, with a gaming score of 48.5%, this CPU's suitability for 3D gaming is below average.
Graphics18.2% is a below average 3D score (RTX 2060S = 100%). This GPU can handle older games but it will struggle to render recent games at resolutions greater than 1080p. (Note: general computing tasks don't require 3D graphics)
Memory8GB is enough RAM to run any version of Windows and it's sufficient for the vast majority of games. 8GB is also enough for moderate file and system caches which result in a very responsive system.
OS VersionAlthough Windows 7 is still a viable option, it's now 14 years and 8 months old. This system should be upgraded to Windows 10 which is generally faster and has an improved set of core utilities including better versions of explorer and task manager.
Very high background CPU (60%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
