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 55.4%, this CPU's suitability for 3D gaming is average.
Graphics1.78% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive32.9% is low SSD score. With a better SSD this system will boot faster, make applications more responsive and reduce IO wait 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.
Sub-optimal background CPU (14%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
