c9gd.24xlarge

Analysis

The c9gd.24xlarge is a compute optimized instance in the c9gd series with 96 vCPUs and 192 GiB of memory on AWS Graviton5 (up to 3.3 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Within the same generation and size, the c9g.24xlarge on AWS Graviton5 costs $4.17/hour, 19% less ($696 a month).

Running it in N. Virginia instead of Tokyo saves $1,013 a month per instance: $5.13/hour against $6.51/hour, a 27% spread. It is not offered in Canada Central, São Paulo, Ireland, London, Mumbai and Sydney, so plan around that if you need a presence there.

Compared with the previous generation, it costs 9.0% more than the c8gd.24xlarge on AWS Graviton4 ($309 more a month per instance), in exchange for the newer processor.

On demand it costs $5.13/hour in US East (N. Virginia), $3,742 a month if left running, which puts it mid-table for compute optimized types at the 65th percentile per vCPU ($0.0534 per vCPU-hour) and the 69th percentile per GiB ($0.0267 per GiB-hour).

Looking beyond its own line, 13 of 22 current types with 96 vCPUs and similar memory are cheaper. The cheapest of those is the c6a.24xlarge on AMD EPYC 7R13 at $3.67/hour.

It has local instance storage (3 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50 Gigabit.
