m9gd.48xlarge

Analysis

The m9gd.48xlarge is a general purpose instance in the m9gd series with 192 vCPUs and 768 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.48xlarge on AWS Graviton5 costs $9.39/hour, 22% less ($1,952 a month).

Running it in N. Virginia instead of Tokyo saves $2,572 a month per instance: $12.07/hour against $15.59/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.48xlarge on AWS Graviton4 ($727 more a month per instance), in exchange for the newer processor.

On demand it costs $12.07/hour in US East (N. Virginia), $8,809 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 3800 GB NVMe SSD), which is fast but lost when the instance stops. Network: 100 Gigabit.

Looking beyond its own line, 10 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.
