Those are 2 different things, vTPM can be used without physical TPM modules in the host.
So vTPM is a VM construct while you could use the physical TPM chips to secure your hosts or to do passthrough for specific use cases
m
So then, is vTPM generally accepted as the recommended path for a vdi deployment?
k
Absolutely, in our lab env we don’t have physical TPMs yet we’ve tested the 💩 out of vTPM (Disclaimer: I work for Nutanix and lead the EUC Solutions team)

Are you aware of limitations of utilizing the physical tpm chips (in passthrough or otherwise) ? This seems to be a case where documentation regarding decision influencing information is sparse. I appreciate your responses.

Here’s some Intel on physical TPM chips, read the performance part: https://blogs.vmware.com/vsphere/2018/04/vsphere-6-7-esxi-tpm-2-0.html
