PC StatusOverall this PC is performing as expected (56th percentile). This means that out of 100 PCs with exactly the same components, 44 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith a relatively low single core score, this CPU can handle email, light web browsing and basic audio/video playback, but it will struggle to handle CPU intensive tasks. Finally, with a gaming score of 17.6%, this CPUs suitability for 3D gaming is very poor.
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.
Memory4GB 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. 4GB is also enough for modest file and system caches which allow for a responsive system.
OS VersionWindows 10 is the most recent version of Windows, and the best to date in our opinion.
Very high background CPU (51%). High background CPU reduces benchmark accuracy. Find active processes with Windows task manager (CTRL+SHIFT+ESC).
