Analysis
The m8gb.16xlarge is a general purpose instance in the m8gb series with 64 vCPUs and 256 GiB of memory on AWS Graviton4 (up to 2.8 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m8g.16xlarge on AWS Graviton4 costs $2.87/hour, 38% less ($1,302 a month). The other variants are the m8i-flex.16xlarge at $3.22, the m8i.16xlarge at $3.39 and the m8gd.16xlarge at $3.69.
Running it in N. Virginia instead of Ireland saves $400 a month per instance: $4.66/hour against $5.20/hour, a 12% spread. It is not offered in Ohio, Canada Central, São Paulo, London, Frankfurt, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.
Per vCPU it is one of the dearer general purpose types: 77% of the 354 current types in the family cost less than its $0.0727 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $4.66/hour in US East (N. Virginia), or $3,399 for a 730-hour month.
Looking beyond its own line, 27 of 35 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.16xlarge on AWS Graviton2 at $2.46/hour.
