m9gd.12xlarge

Analysis

The m9gd.12xlarge is a general purpose instance in the m9gd series with 48 vCPUs and 192 GiB of memory on AWS Graviton5 (up to 3.3 GHz), which makes it balanced at 4 GiB of memory per vCPU.

Within the same generation and size, the m9g.12xlarge on AWS Graviton5 costs $2.35/hour, 22% less ($488 a month).

Running it in N. Virginia instead of Tokyo saves $643 a month per instance: $3.02/hour against $3.90/hour, a 29% spread. It is not offered in Canada Central, São Paulo, London and Mumbai, so plan around that if you need a presence there.

Compared with the previous generation, it costs 9.0% more than the m8gd.12xlarge on AWS Graviton4 ($182 more a month per instance), in exchange for the newer processor.

On demand it costs $3.02/hour in US East (N. Virginia), $2,202 a month if left running, which puts it mid-table for general purpose types at the 65th percentile per vCPU ($0.0629 per vCPU-hour) and the 65th percentile per GiB ($0.0157 per GiB-hour).

It has local instance storage (3 x 950 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.

Looking beyond its own line, 21 of 36 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.12xlarge on AWS Graviton2 at $1.85/hour.
