It depends. There was a reason back in the day that if you were a telco you have phone switches from from 2 providers,ie a DMSxxx and ESSxxx. Another example would be how the big providers got screwed by the in ability of Cisco to get their GSR working right without a few forklift upgrades (really they were moved with a forklift). This opened the path for Juniper. For a long time the telcos moved to have one router from each so a nasty bug in one would not take them down. In a properly tooled setup you should be able to account for the load characteristics between AMD and Intel. Having 2 is safer then one.
Google is pushing both PowerCPU development as well as ARM. They seem to be able to sort for this just fine. You can write tools to sort the differences. You cannot write tools to fix major HW issue.
Anyway my 2 cents based on experience and history for whatever the comments of a random person on the intertubes is worth.
