Analysis
The m6i.16xlarge is a general purpose instance in the m6i series with 64 vCPUs and 256 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m6g.16xlarge on AWS Graviton2 costs $2.46/hour, 20% less ($444 a month), though switching means rebuilding software for arm64. The other variants are the m6a.16xlarge at $2.76, the m6gd.16xlarge at $2.89 and the m6id.16xlarge at $3.80.
Running it in N. Virginia instead of São Paulo saves $1,332 a month per instance: $3.07/hour against $4.90/hour, a 59% spread.
On demand it costs $3.07/hour in US East (N. Virginia), $2,243 a month if left running, which puts it mid-table for general purpose types at the 29th percentile per vCPU ($0.0480 per vCPU-hour) and the 28th percentile per GiB ($0.0120 per GiB-hour).
Reserving it for a year with no upfront payment cuts the Linux rate to $2.03/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $1.39/hour, 55% below on demand. Windows Server roughly doubles the bill at $6.02/hour, because the licence is charged per vCPU.
The newer m7i.16xlarge on Intel Xeon Scalable (Sapphire Rapids) is 5.0% dearer at $3.23/hour.
