Understanding the VMware ESXi limitations of the free Version
Solution 1:
Those two stats you mention are different; it's 8 virtualised CPUs per VM and 2 physical CPU sockets that they're talking about - not the same thing. BTW if you're going with the free version have a look at THIS great new ESXi add-in that gives you a vCenter-like interface into your host via a web client - it's really new and really useful :)
Solution 2:
Free version Hypervisor (Esxi) Version 6.0
- 2 (physical) CPU limit
- No Ram limit (removed since 5.5)
Hypervisor Spec
- Number of cores per physical CPU: No limit
- Number of physical CPUs per host: No limit
- Number of logical CPUs per host: 480
- Maximum vCPUs per virtual machine: 8

Solution 3:
When you apply the ESXi 6 free license, it appears :
Product : VMware vSphere Hypervisor Licenced 6 for 2 physical CPUs ( unlimited cores per CPU)
Product features:
Up to 8 -way virtual SMP
