m8in.32xlarge

Analysis

The m8in.32xlarge is a general purpose instance in the m8in 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, 37% less ($2,861 a month). The other variants are the m8id.32xlarge at $8.35, the m8ib.32xlarge at $10.69 and the m8idn.32xlarge at $12.22.

Running it in N. Virginia instead of Tokyo saves $2,230 a month per instance: $10.69/hour against $13.75/hour, a 29% spread. It is not offered in Canada Central, São Paulo, London, Frankfurt, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer general purpose types: 87% of the 354 current types in the family cost less than its $0.0835 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $10.69/hour in US East (N. Virginia), or $7,806 for a 730-hour month.

Looking beyond its own line, 8 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.
