Performance Results


Gaming 7% Tree trunk	Desktop 55% Yacht	Workstation 6% Tree trunk


PC Status	Overall this PC is performing way below expectations (19th percentile). This means that out of 100 PCs with exactly the same components, 81 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
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 59.7%, this CPU's suitability for 3D gaming is average.
Graphics	1.22% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	48.4% is a reasonable SSD score. This drive enables fast boots and responsive applications.
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 8.1 is a recent version of Windows, it's worth upgrading to Windows 10 which has had several improvements made to the user interface including a better homescreen.

CPU throttled at 99% by Windows. Ensure maximum processor state is set to 100% via Settings > System > Power & sleep > Additional power settings > Change plan settings > Change advanced power settings > Processor power management > Maximum processor state.
