Curious what type of workload you are using them for?
We're a VMware shop so I'd be hesitant to deploy non-Intel just because I don't want to get caught holding the bag in case AMD can't keep their momentum up for the next 5 years when we'd most likely looking to lifecycle the environment.
Manufacturing is weird like that. We like VMware because we can refresh our compute and storage without downtime, since a lot (almost al) of the applications are not built for HA.
