Analysis
The m5zn.12xlarge is a general purpose instance in the m5zn series with 48 vCPUs and 192 GiB of memory on Intel Xeon Platinum 8252 (up to 4.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m5a.12xlarge on AMD EPYC 7571 costs $2.06/hour, 48% less ($1,387 a month). The other variants are the m5.12xlarge at $2.30, the m5ad.12xlarge at $2.47 and the m5d.12xlarge at $2.71.
Running it in N. Virginia instead of São Paulo saves $1,718 a month per instance: $3.96/hour against $6.32/hour, a 59% spread. It is not offered in Canada Central, London and Mumbai, so plan around that if you need a presence there.
Per vCPU it is one of the dearer general purpose types: 83% of the 354 current types in the family cost less than its $0.0826 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $3.96/hour in US East (N. Virginia), or $2,894 for a 730-hour month.
Looking beyond its own line, 28 of 36 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.12xlarge on AWS Graviton2 at $1.85/hour.
It is the largest of the 6 m5zn sizes. Dropping to the m5zn.6xlarge saves $1,447 a month.
