This is an awesome write up. I love reading these warts and all accounts - they're always way more useful than the typical case study "we switched to X and it saved us Y%!" marketing posts. One point that makes Intel not look quite so bad performance wise - based on my own benchmarking, I'm pretty sure when this article talks about cores they actually mean vCPUs. In AWS on x86, 1 vCPU is 1 hyperthread, so it's kind of half a core. On Graviton 2, 1 vCPU is one full core, the CPUs don't have hyperthreading. This means that you need 10 Intel cores to do the same work as 16 Graviton cores, not 20. This of course doesn't change the cost savings from switching to arm64.
