Where the data on the CPU page of the Computer window comes from. See Computer Window Data Sources for how to read the Source column, and for the other pages of the Computer window.

Collected by the Computer scanner from WMI Win32_Processor.

Totals

Field	Source	Derivation / Notes
Total Processors	WMI	The number of Win32_Processor instances, which is the number of populated sockets.
Total Physical Cores	Calculated	Total Processors multiplied by Physical Cores.
Total Logical Cores	Calculated	Total Processors multiplied by Logical Core.
Total Enabled Cores	Calculated	Total Processors multiplied by Enabled Cores.

NOTE: The per-processor values below are read from the first processor only, and the totals multiply them by the socket count. On the rare system with mismatched processors the totals will be wrong.

Processor

Field	Source	Derivation / Notes
Name	WMI	Win32_Processor.Name.
Description	WMI	Win32_Processor.Description - family, model, and stepping.
Processor Speed MHz	WMI	Win32_Processor.MaxClockSpeed - the rated base speed, not the current or boost speed.
L2 Cache	WMI	Win32_Processor.L2CacheSize, reported by WMI in KB.
L3 Cache	WMI	Win32_Processor.L3CacheSize, reported by WMI in KB.
Manufacturer	WMI	Win32_Processor.Manufacturer.
Architecture	Calculated	Win32_Processor.Architecture decoded to 32-bit (x86), 32-bit (ARM), 64-bit (Itanium), 64-bit (x64), or 64-bit (ARM64). On ARM hardware the host's real architecture takes precedence, so a scanner running under x64 emulation is still reported as ARM64.
Physical Cores	WMI	Win32_Processor.NumberOfCores.
Logical Core	WMI	Win32_Processor.NumberOfLogicalProcessors - threads, so twice the physical cores where hyper-threading is on.
Enabled Cores	WMI	Win32_Processor.NumberOfEnabledCore.
Asset Tag	WMI	Win32_Processor.AssetTag. Blank unless the value is set in firmware.
