ProcessorWith 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.
Graphics5.54% 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 Drive85.3% 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.
Memory12GB 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 VersionWindows 11 is the most recent version of Windows, and the best to date in our opinion.
