Topic Name : Add a Virtual Machine to a Resource Pool

Publication Name : vSphere Resource Management

Product/Version : VMware vSphere/6.5

Question :

Can someone explain the relationship between the vCPU designated for a VM and the CPU resources available in a Resource pool?  For example, if a VM with 2 vCPU and a VM with 4 vCPU have equal shares defined in a Resource Pool, don't they then have the same processing power?  Hope this makes sense.
