c9gd.48xlarge

Analysis

The c9gd.48xlarge is a compute optimized instance in the c9gd series with 192 vCPUs and 384 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.48xlarge on AWS Graviton5 costs $8.35/hour, 19% less ($1,392 a month).

Running it in N. Virginia instead of Tokyo saves $2,027 a month per instance: $10.25/hour against $13.03/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.48xlarge on AWS Graviton4 ($618 more a month per instance), in exchange for the newer processor.

On demand it costs $10.25/hour in US East (N. Virginia), $7,485 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).

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, 7 of 14 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the c6a.48xlarge on AMD EPYC 7R13 at $7.34/hour.
