This was not about a GHz requirement but a number of cores recommendation. The https://docs.microsoft.com/en-us/microsoftteams/teams-for-vdi document or others that I had previously found USED to says the recommended number of cores for Teams was 4. It's been awhile since I looked at it so I assumed it's changed but I'm positive that it used to say 4 was the recommended number in a virtual environment.
