Makes sense AMD gave up.
The purpose of switching to ARM was better density, with a Xeon server you can saturate a 1Gbps Ethernet connection (or even 10Gbps) and still have processing power to spare, but Intel are stingy on PCI-e lanes so you can't just add more and more ports. So if 80% of your CPU power is going spare then why do you even need it? An ARM server can be much denser, you can fit 10 servers in a 1U space, each with their own Ethernet port.
But now with AMD's Zen design they have lots of PCI-e lanes and lots of cores, so you have have 1 system running 10 VMs. This is even better then having 10 separate machines in the same space, as with VMs you can over provision resources.
