Analysis
The r5dn.8xlarge is a memory optimized instance in the r5dn series with 32 vCPUs and 256 GiB of memory on Intel Xeon Platinum 8259 (Cascade Lake) (up to 3.1 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r5a.8xlarge on AMD EPYC 7571 costs $1.81/hour, 32% less ($631 a month). The other variants are the r5.8xlarge at $2.02, the r5ad.8xlarge at $2.10 and the r5d.8xlarge at $2.30.
Running it in N. Virginia instead of Sydney saves $432 a month per instance: $2.67/hour against $3.26/hour, a 22% spread. It is not offered in Canada Central, São Paulo, London and Mumbai, so plan around that if you need a presence there.
On demand it costs $2.67/hour in US East (N. Virginia), $1,951 a month if left running, which puts it mid-table for memory optimized types at the 57th percentile per vCPU ($0.0835 per vCPU-hour) and the 73rd percentile per GiB ($0.0104 per GiB-hour).
Looking beyond its own line, 26 of 41 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.8xlarge on AWS Graviton2 at $1.61/hour.
It has local instance storage (2 x 600 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.
