Analysis
The m8i-flex.8xlarge is a general purpose instance in the m8i-flex series with 32 vCPUs and 128 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m8g.8xlarge on AWS Graviton4 costs $1.44/hour, 11% less ($126 a month), though switching means rebuilding software for arm64. The other variants are the m8i.8xlarge at $1.69, the m8gd.8xlarge at $1.85 and the m8a.8xlarge at $1.95.
Running it in N. Virginia instead of São Paulo saves $697 a month per instance: $1.61/hour against $2.56/hour, a 59% spread.
On demand it costs $1.61/hour in US East (N. Virginia), $1,174 a month if left running, which puts it mid-table for general purpose types at the 36th percentile per vCPU ($0.0503 per vCPU-hour) and the 36th percentile per GiB ($0.0126 per GiB-hour).
Compared with the previous generation, it costs 5.0% more than the m7i-flex.8xlarge on Intel Xeon Scalable (Sapphire Rapids) ($55.95 more a month per instance), in exchange for the newer processor.
Looking beyond its own line, 10 of 37 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.8xlarge on AWS Graviton2 at $1.23/hour.
