Newer ryzen chips don't have amd-vi?

[Thibaultmol]

I noticed that AMD started to exclude ‘amd-vi’ from lower end chips.
LIke, you used to see something like a Ryzen 5 3600 with amd-vi but now it’s limited to Ryzen 9’s?

How much would I be missing out on if I plan to have a proxmox machine to do gaming/vr with inside a vm and choose something like a 7800X3D (which only has amd-v, not amd-vi)

AMD-V is supported but not Vi for both 5 and 9:

• AMD Ryzen 5 7600X
• AMD Ryzen 9 7900X

I have a Ryzen 7 which is working perfectly fine with Proxmox.

Seems like every 7000 series supports AMD-V
but non support amd-vi?
even though they do have IOMMU?

I’m wondering how much VI specifically contributes to the experience…

[Thibaultmol]

OH… so amd-vi isn’t a thing anymore and you just need to make sure you get a motherboard that has IOMMU built in?..

I thought AMD-Vi and Intel VT-d were just brand names for the same feature, IOMMU.

Kinda yeah. But what confused me was that for ryzen it depends on the mobo. While for intel it depends on the cpu. (cause it’s where the chipset is located I guess?)
