r9gd.16xlarge

Analysis

The r9gd.16xlarge is a memory optimized instance in the r9gd series with 64 vCPUs and 512 GiB of memory on AWS Graviton5 (up to 3.3 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r9g.16xlarge on AWS Graviton5 costs $4.11/hour, 20% less ($742 a month).

Running it in N. Virginia instead of Frankfurt saves $754 a month per instance: $5.13/hour against $6.16/hour, a 20% spread. It is not offered in Canada Central, São Paulo, Ireland, London, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.

Compared with the previous generation, it costs 9.0% more than the r8gd.16xlarge on AWS Graviton4 ($309 more a month per instance), in exchange for the newer processor.

Looking beyond its own line, 24 of 39 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.16xlarge on AWS Graviton2 at $3.23/hour.

It has local instance storage (1 x 3800 GB NVMe SSD), which is fast but lost when the instance stops. Network: 34 Gigabit.

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 memory optimized types at the 51st percentile per vCPU ($0.0801 per vCPU-hour) and the 67th percentile per GiB ($0.0100 per GiB-hour).
