r8id.32xlarge

Analysis

The r8id.32xlarge is a memory optimized instance in the r8id series with 128 vCPUs and 1024 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r8i.32xlarge on Intel Xeon Scalable (Granite Rapids) costs $8.89/hour, 16% less ($1,280 a month). The other variants are the r8ib.32xlarge at $13.39, the r8in.32xlarge at $13.39 and the r8idn.32xlarge at $15.01.

Running it in N. Virginia instead of Tokyo saves $1,619 a month per instance: $10.64/hour against $12.86/hour, a 21% spread. It is not offered in São Paulo and Singapore, so plan around that if you need a presence there.

It has local instance storage (2 x 3800 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50000 Megabit.

On demand it costs $10.64/hour in US East (N. Virginia), $7,770 a month if left running, which puts it mid-table for memory optimized types at the 54th percentile per vCPU ($0.0832 per vCPU-hour) and the 71st percentile per GiB ($0.0104 per GiB-hour).

Looking beyond its own line, 5 of 14 current types with 128 vCPUs and similar memory are cheaper. The cheapest of those is the r6a.32xlarge on AMD EPYC 7R13 at $7.26/hour.
