PC StatusOverall this PC is performing as expected (59th percentile). This means that out of 100 PCs with exactly the same components, 41 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith a good single core score, this CPU can easily handle the majority of general computing tasks. Despite its good single core score this processor isn't appropriate for workstation use due to its relatively weak multi-core performance. Finally, with a gaming score of 71.2%, this CPU's suitability for 3D gaming is good.
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.
Memory5GB is enough RAM to run any version of Windows and it's sufficient for the vast majority of games. 5GB 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.
High background CPU (25%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
