For a Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz model cpu I am getting both the NumberOfCores and NumberOfLogicalProcessors as 4 .
I want to know how system is calculating NumberOfLogicalProcessors ?
What i should use to get the actual number of cpus ?
OS: win2k8 R2
That depends on what you meant by actual CPU.
Win32_Processor\NumberOfCoresspecifies the total number of physical CPU cores. A chip can contain one or more CPU cores.Win32_Processor\NumberOfLogicalProcessorsspecifies the total number of virtual CPU cores. There can be two or more virtual CPU cores in one physical CPU core. On x86 compatible computers, this is only available in Intel’s Hyper-Threading capable CPUs.On the other hand, the
Win32_ComputerSystem\NumberOfProcessorsspecifies the total number of physical processor chips installed on a multi processor motherboard.The
Win32_ComputerSystem\NumberOfLogicalProcessorsis same asWin32_Processor\NumberOfLogicalProcessors.
