Performance Results


Gaming 8% Tree trunk	Desktop 61% Destroyer	Workstation 7% Tree trunk


PC Status	Overall this PC is performing as expected (50th percentile). This means that out of 100 PCs with exactly the same components, 50 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With 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 65.5%, this CPU's suitability for 3D gaming is above average.
Graphics	3.46% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	88.6% is a very good SSD score. This drive is suitable for moderate workstation use, it will facilitate fast boots, responsive applications and ensure minimum IO wait times.
Memory	16GB is enough RAM to run any version of Windows and it's more than sufficient for nearly all games. 16GB also allows for very large file and system caches, software development and batch photo editing/processing.
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 (13%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
