Analysis
The m8g.16xlarge is a general purpose instance in the m8g series with 64 vCPUs and 256 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $1,843 a month per instance: $2.05/hour against $4.58/hour, a 123% spread.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The m8a.16xlarge on AMD EPYC 9R45 costs 36% more, and the m8i-flex.16xlarge, the m8i.16xlarge and the m8gd.16xlarge also sit above it.
At $2.87/hour on demand in US East (N. Virginia), about $2,097 a month, the m8g.16xlarge is one of the cheaper ways to buy general purpose capacity: only 20% of the 354 current general purpose types cost less per vCPU-hour than its $0.0449.
Compared with the previous generation, it costs 10% more than the m7g.16xlarge on AWS Graviton3 ($191 more a month per instance), in exchange for the newer processor. The newer m9g.16xlarge on AWS Graviton5 is 9.0% dearer at $3.13/hour.
Looking beyond its own line, 4 of 35 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.16xlarge on AWS Graviton2 at $2.46/hour.
