Understanding System Information for a virtual machine

I love Geekbench 4! Recently I've been in interested in performance comparisons between bare metal and VM systems.

Recently I've come across an observation of how Geekbench represents the number of vCPUs for a VM. As seen in the attached screenshot, Geekbench is reporting the processor having 8 cores, which I suspect is impossible because the processor (Xeon E3-1505M v5) is only quad-core.

I understand the hypervisor will determine the # of vCPU per core, however, from my own testing it appears Geekbench is detecting the # of vCPUs and is incorrectly reporting this as # of cores.

If so, that's fine. I'm more just curious if this will be consistent across all virtual environments.

Thanks!

    Hello,

    Thanks for your message, and I apologize for the delayed response. You are correct that how Geekbench reports the topology depends on how the virtualization layer exposes the underlying topology to the guest OS. This should be consistent across virtual environments.
