m7i.large

Analysis

The m7i.large is a general purpose instance in the m7i series with 2 vCPUs and 8 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 3.2 GHz), which makes it balanced at 4 GiB of memory per vCPU.

Within the same generation and size, the m7g.large on AWS Graviton3 costs $0.0816/hour, 19% less ($14.02 a month), though switching means rebuilding software for arm64. The other variants are the m7i-flex.large at $0.0958, the m7gd.large at $0.1068 and the m7a.large at $0.1159.

Running it in N. Virginia instead of São Paulo saves $43.69 a month per instance: $0.1008/hour against $0.1606/hour, a 59% spread.

Reserving it for a year with no upfront payment cuts the Linux rate to $0.0667/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $0.0457/hour, 55% below on demand. Windows Server roughly doubles the bill at $0.1928/hour, because the licence is charged per vCPU.

On demand it costs $0.1008/hour in US East (N. Virginia), $73.58 a month if left running, which puts it mid-table for general purpose types at the 39th percentile per vCPU ($0.0504 per vCPU-hour) and the 39th percentile per GiB ($0.0126 per GiB-hour).

Compared with the previous generation, it costs 5.0% more than the m6i.large on Intel Xeon 8375C (Ice Lake) ($3.50 more a month per instance), in exchange for the newer processor. The newer m8i.large on Intel Xeon Scalable (Granite Rapids) is 5.0% dearer at $0.1058/hour.
