Hyperthreading works by providing a second execution thread to a processor core. Please note that hyperthreading does not actually double the available pCPU. If the cores use hyperthreading, the number of logical cores is calculated as: (# pCPU) X (2 threads/physical processor) = # Virtual Processors (vCPU)įor example, if you have 2 processors with 6 cores each: (2 Processor Sockets) X (6 Cores/Processor) = 12 Physical Processors (pCPU) (12 pCPU) X (2 threads/physical processor) = 24 Virtual Processors (vCPU) The number of physical cores (pCPU) available on a host is calculated as: (# Processor Sockets) X (# Cores/Processor) = # Physical Processors (pCPU)
