Analysis
The m8gd.16xlarge is a general purpose instance in the m8gd series with 64 vCPUs and 256 GiB of memory on AWS Graviton4 (up to 2.7 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, 22% less ($597 a month). The other variants are the m8i-flex.16xlarge at $3.22, the m8i.16xlarge at $3.39 and the m8a.16xlarge at $3.90.
Running it in Mumbai instead of São Paulo saves $2,500 a month per instance: $2.45/hour against $5.88/hour, a 140% spread.
Compared with the previous generation, it costs 8.0% more than the m7gd.16xlarge on AWS Graviton3 ($199 more a month per instance), in exchange for the newer processor. The newer m9gd.16xlarge on AWS Graviton5 is 9.0% dearer at $4.02/hour.
It has local instance storage (2 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 30 Gigabit.
On demand it costs $3.69/hour in US East (N. Virginia), $2,694 a month if left running, which puts it mid-table for general purpose types at the 52nd percentile per vCPU ($0.0577 per vCPU-hour) and the 52nd percentile per GiB ($0.0144 per GiB-hour).
Looking beyond its own line, 17 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.
