Microsoft engineer Raymond Chen clarified why Windows sometimes reports two different CPU speeds in the Settings app. The initial figure displayed is usually part of the processor brand string, often sourced from CPUID function codes used by manufacturers. In contrast, the second figure reflects a rough speed calculation performed by Windows. This discrepancy may assist in identifying overclocked systems or misleading marketing claims. For reliable speed metrics, Microsoft recommends checking the Task Manager's Performance tab instead.
Windows displays CPU information showing two speeds: one from the processor brand string and another from Windows' own calculation. This can cause confusion for users.
Chen suggests that the discrepancy in CPU speeds might stem from manufacturers including their own calculated speeds in the brand string to market their products.
