AMD has had these sorts of densities available for a minute.

I have done this math recently, and you need to stop cherry picking and move everything. And build a redundant data center to boot.

Compute is NOT the major issue for this sort of move:

Switching and bandwidth will be major costs. 400gb is a minimum for interconnects and for most orgs you are going to need at least that much bandwidth top of rack.

Storage remains problematic. You might be able to amortize compute over this time scale, but not storage. 5 years would be pushing it (depending on use). And data center storage at scale was expensive before the recent price spike. Spinning rust is viable for some tasks (backup) but will not cut it for others.

Human capital: Figuring out how to support the hardware you own is going to be far more expensive than you think. You need to expect failures and staff accordingly, that means resources who are going to be, for the most part, idle.
