m8id.32xlarge

Analysis

The m8id.32xlarge is a general purpose instance in the m8id series with 128 vCPUs and 512 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it balanced at 4 GiB of memory per vCPU.

Within the same generation and size, the m8i.32xlarge on Intel Xeon Scalable (Granite Rapids) costs $6.77/hour, 19% less ($1,153 a month). The other variants are the m8in.32xlarge at $10.69, the m8ib.32xlarge at $10.69 and the m8idn.32xlarge at $12.22.

Running it in N. Virginia instead of Tokyo saves $1,780 a month per instance: $8.35/hour against $10.79/hour, a 29% spread. It is not offered in São Paulo and Singapore, so plan around that if you need a presence there.

On demand it costs $8.35/hour in US East (N. Virginia), $6,098 a month if left running, which puts it mid-table for general purpose types at the 68th percentile per vCPU ($0.0653 per vCPU-hour) and the 68th percentile per GiB ($0.0163 per GiB-hour).

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

Looking beyond its own line, 5 of 12 current types with 128 vCPUs and similar memory are cheaper. The cheapest of those is the m6a.32xlarge on AMD EPYC 7R13 at $5.53/hour.
