Performance Results


Gaming 7% Tree trunk	Desktop 49% Yacht	Workstation 6% Tree trunk


PC Status	Overall this PC is performing as expected (54th percentile). This means that out of 100 PCs with exactly the same components, 46 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a below average single core score, this CPU can handle email, web browsing and audio/video playback but it will struggle to handle modern 3D games or workstation tasks such as video editing. Finally, with a gaming score of 46.8%, this CPU's suitability for 3D gaming is below average.
Graphics	9.37% 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 Drive	38% is low SSD score. With a better SSD this system will boot faster, make applications more responsive and reduce IO wait times.
Memory	8GB 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 Version	Although 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.

Sub-optimal background CPU (20%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
