It is an important distinction between designing an SOC with ARM provided cores and designing the cores from scratch. People on this thread are comparing AWS’s achievement to the M1, but that’s just in a totally different ballpark. Obviously still hard to design custom silicon and custom servers around it, but it’s fair to say that’s a for cry from “optimizing the cores for the workloads that run on EC2” as has been suggested in this thread.
