Not in Google’s case. There vCPU == hyperthread. To quote https://cloud.google.com/compute/docs/machine-types https://cloud.google.com/compute/docs/machine-types: "For the n1 series of machine types, a vCPU is implemented as a single hardware hyper-thread". One more area where Google is more explicit. Only their partial vCPU instances are timesliced: "Shared-core machine types provide one vCPU that is allowed to run for a portion of the time on a single hardware hyper-thread on the host CPU running your instance".
