Performance Results


Gaming 10% Tree trunk	Desktop 63% Destroyer	Workstation 9% Tree trunk


PC Status	Overall this PC is performing way above expectations (90th percentile). This means that out of 100 PCs with exactly the same components, 10 performed better. The overall PC percentile is the average of each of its individual components. This PC is likely operated by a technical master!
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 63.7%, this CPU's suitability for 3D gaming is above average.
Graphics	7.31% 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	186% is an exceptional SSD score. This drive is suitable for heavy workstation use, it will facilitate fast boots, responsive applications and allow for fast transfers of multi-gigabyte files.
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 10 is not the most recent version of Windows, it remains a great option.

CPU throttled at 89% 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.
