-^[1]^ 1 physical core provides 2 vCPUs when hyper-threading is enabled. 1 physical core provides 1 vCPU when hyper-threading is not enabled.
+1. 1 vCPU is equivalent to 1 physical core when simultaneous multithreading (SMT), or hyperthreading, is not enabled. When enabled, use the following formula to calculate the corresponding ratio: (threads per core × cores) × sockets = vCPUs.
