Below is a table that lists AMD's equivalent technologies to the ones you highlighted as being interested in.
AMD Intel AMD-Vi (IOMMU) VT-d (I/O MMU virtualization) AMD-V (Virtualization) VT-x (Virtualization) Rapid Virtualization Indexing (RVI) Extended Page Tables (EPT)
These features are included on all Zen based processors which are included in the two you highlighted.
VMware ESXi 6.7 is only officially supported on our AMD EPYC processors, I would recommend that you reach out to them to determine if the functionality you require is supported on our AMD Threadripper or AMD Ryzen processors. Additionally, if you are using a NIC faster than 25GbE I would also recommend that you look at one of our technical documents here to help you optimize your NIC for best performance on VMware ESXi.
Thank you for the answer.
KVM is of crucial importance as it traditionally outpaced ESXi in terms of performance (especially IO) and is going to be the primary hypervisor.
Sadly, it seems Threadripper has some issues with Nested Pages Table when used with KVM.
