VM vCPU sockets vs logical processor

Does it make a difference in performance if I configure the vCPU on a VM using multiple sockets vs 1 socket and multiple cores

If I needed 8 vCPU, for example will i get better performance using 8 sockets or 1 socket and 8 cores

Thanks in advance !

Yes, it does make a difference, although do note that this subject is one of protracted discussion as there are lots of technicals involved. The short way to state this is the following:  Unless you have specific concerns or use cases (like licensing), always configure sockets over cores.
