Analysis
The m6i.12xlarge is a general purpose instance in the m6i series with 48 vCPUs and 192 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.12xlarge on AWS Graviton2 costs $1.85/hour, 20% less ($333 a month), though switching means rebuilding software for arm64. The other variants are the m6a.12xlarge at $2.07, the m6gd.12xlarge at $2.17 and the m6id.12xlarge at $2.85.
Running it in N. Virginia instead of São Paulo saves $999 a month per instance: $2.30/hour against $3.67/hour, a 59% spread.
On demand it costs $2.30/hour in US East (N. Virginia), $1,682 a month if left running, which puts it mid-table for general purpose types at the 27th percentile per vCPU ($0.0480 per vCPU-hour) and the 25th percentile per GiB ($0.0120 per GiB-hour).
Reserving it for a year with no upfront payment cuts the Linux rate to $1.52/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $1.05/hour, 55% below on demand. Windows Server roughly doubles the bill at $4.51/hour, because the licence is charged per vCPU.
The newer m7i.12xlarge on Intel Xeon Scalable (Sapphire Rapids) is 5.0% dearer at $2.42/hour.
