r6id.32xlarge

Analysis

The r6id.32xlarge is a memory optimized instance in the r6id series with 128 vCPUs and 1024 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r6a.32xlarge on AMD EPYC 7R13 costs $7.26/hour, 25% less ($1,766 a month). The other variants are the r6i.32xlarge at $8.06, the r6in.32xlarge at $11.16 and the r6idn.32xlarge at $12.50.

Running it in N. Virginia instead of Singapore saves $1,472 a month per instance: $9.68/hour against $11.69/hour, a 21% spread. It is not offered in Canada Central and São Paulo, so plan around that if you need a presence there.

On demand it costs $9.68/hour in US East (N. Virginia), $7,064 a month if left running, which puts it mid-table for memory optimized types at the 43rd percentile per vCPU ($0.0756 per vCPU-hour) and the 59th percentile per GiB ($0.00945 per GiB-hour).

It has local instance storage (4 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50000 Megabit.

Looking beyond its own line, 3 of 14 current types with 128 vCPUs and similar memory are cheaper. The cheapest of those is the r8i.32xlarge on Intel Xeon Scalable (Granite Rapids) at $8.89/hour.
