m7a.32xlarge

Analysis

The m7a.32xlarge is a general purpose instance in the m7a series with 128 vCPUs and 512 GiB of memory on AMD EPYC 9R14 (up to Up to 3.7 GHz), which makes it balanced at 4 GiB of memory per vCPU.

Compared with the previous generation, it costs 34% more than the m6a.32xlarge on AMD EPYC 7R13 ($1,379 more a month per instance), in exchange for the newer processor.

Running it in N. Virginia instead of Tokyo saves $1,580 a month per instance: $7.42/hour against $9.58/hour, a 29% spread. It is not offered in Canada Central, São Paulo, Mumbai and Singapore, so plan around that if you need a presence there.

On demand it costs $7.42/hour in US East (N. Virginia), $5,416 a month if left running, which puts it mid-table for general purpose types at the 54th percentile per vCPU ($0.0580 per vCPU-hour) and the 54th percentile per GiB ($0.0145 per GiB-hour).

Looking beyond its own line, 3 of 12 current types with 128 vCPUs and similar memory are cheaper. The cheapest of those is the m6i.32xlarge on Intel Xeon 8375C (Ice Lake) at $6.14/hour.

It is size 10 of 11 in the m7a series. Stepping up to the m7a.48xlarge gives 192 vCPUs and 768 GiB for $2,708 more a month. Dropping to the m7a.24xlarge saves $1,354 a month.
