Excerpt
Core-pair: This is 1 of the bases for self-managed OpenShift subscriptions. It is defined as 2 physical cores or as 4 virtual central processing units (vCPUs). On a bare-metal machine, it always refers to the physical core, regardless of any hyperthreading or symmetric multithreading technology. If hyperthreading is turned on, then 2 physical cores that present as 4 vCPU are still counted as a single core-pair. For hyperscaler deployments, e.g. AWS, Azure, and GCP, 4 vCPU are always considered a single core-pair.
