Analysis
The m7i-flex.16xlarge is a general purpose instance in the m7i-flex series with 64 vCPUs and 256 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 3.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m7g.16xlarge on AWS Graviton3 costs $2.61/hour, 15% less ($331 a month), though switching means rebuilding software for arm64. The other variants are the m7i.16xlarge at $3.23, the m7gd.16xlarge at $3.42 and the m7a.16xlarge at $3.71.
Running it in N. Virginia instead of São Paulo saves $1,328 a month per instance: $3.06/hour against $4.88/hour, a 59% spread.
At $3.06/hour on demand in US East (N. Virginia), about $2,237 a month, the m7i-flex.16xlarge is one of the cheaper ways to buy general purpose capacity: only 25% of the 354 current general purpose types cost less per vCPU-hour than its $0.0479.
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 $6.01/hour, because the licence is charged per vCPU.
The newer m8i-flex.16xlarge on Intel Xeon Scalable (Granite Rapids) is 5.0% dearer at $3.22/hour.
