PC StatusOverall this PC is performing below expectations (31st percentile). This means that out of 100 PCs with exactly the same components, 69 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
ProcessorWith an extremely low single core score, this CPU can barely handle email and light web browsing. Finally, with a gaming score of 16.7%, this CPU's suitability for 3D gaming is terrible.
Graphics10.6% is a very low 3D score (RTX 2060S = 100%). This GPU can only handle very basic 3D games but it's fine for general computing tasks.
Boot DriveThe boot partition is located on a mechanical or hybrid drive. Moving the system to an SSD will yield far faster boot times, better system responsiveness and faster application load times.
Memory3GB is enough RAM to run any version of Windows and although it's sufficient for most games, some will benefit from up to 8GB of RAM. 3GB is also enough for modest file and system caches which allow for a responsive system.
OS VersionAlthough Windows 7 is still a viable option, it's now 14 years and 9 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 (65%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
