m8g.48xlarge

Analysis

The m8g.48xlarge is a general purpose instance in the m8g series with 192 vCPUs and 768 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 $5,529 a month per instance: $6.16/hour against $13.73/hour, a 123% spread.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The m8id.48xlarge on Intel Xeon Scalable (Granite Rapids) costs 45% more, and the m8i.48xlarge, the m8gd.48xlarge and the m8a.48xlarge also sit above it.

At $8.62/hour on demand in US East (N. Virginia), about $6,290 a month, the m8g.48xlarge 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.

The newer m9g.48xlarge on AWS Graviton5 is 9.0% dearer at $9.39/hour.

Looking beyond its own line, 3 of 18 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the hpc7a.96xlarge on AMD EPYC 9R14 at $7.20/hour.

It is the largest of the 10 m8g sizes. Dropping to the m8g.24xlarge saves $3,145 a month.

Reserving it for a year with no upfront payment cuts the Linux rate to $5.70/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $3.91/hour, 55% below on demand.
