Performance Results


Gaming 9% Tree trunk	Desktop 66% Battle cruiser	Workstation 9% Tree trunk


PC Status	Overall this PC is performing above expectations (60th percentile). This means that out of 100 PCs with exactly the same components, 40 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 62.5%, this CPU's suitability for 3D gaming is above average.
Graphics	4.85% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	85.3% 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	12GB is enough RAM to run any version of Windows and it's more than sufficient for nearly all games. 12GB also allows for very large file and system caches, software development and batch photo editing/processing.
OS Version	Windows 11 is the most recent version of Windows.

CPU throttled at 90% 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.
