Number of sockets vs cores

Hi,

Can't find any relevant article about vmware  performance in case of multi socket architecture vs single socket. For instance if I have 2 CPUs of 8 cores (16) cores or single CPU with 16 cores, and I'm mapping 1 physical CPU  to 3 vCPUs.

Can anybody point difference between this two architecture that is relevant for performance?

Thanks
