Hi Guys,
i've been looking anywhere but cannot find an answer to my question.
so for lab purposes i installed ESXi 6.0 under a laptop run by a processor i5-5200U
hyperthreading is already on.
this processor supposed to have 4 cores in one socket but in the information i only see 2 on "Processor Cores per socket".
someone have any input of what am i missing here? i was expecting 8 vCPU with 4 cores processor and hyperthreading on.
here is the screenshot:

i5-5200U is 2 core/4 thread so ESXi can only have 4 logical processors.

For ESXi to have 8 vCPUs, the CPU needs to be 4 core/8 thread; or for dual socket server/workstation, 2 CPU sockets, each with 4 cores without hyperthreading also results in 8 logical processors.

Hyper-threading: For each processor core that is physically present, the operating system addresses two virtual (logical) cores and shares the workload between them when possible.
2 cores with Hyper-threading are 4 threads.
I totally agree with whats been mentioned before and also the link shared by bluefirestorm
Thank you guys,
i was under impression that all i5 family has 4 cores. turns out that was not right.
