Analysis
The c6gn.16xlarge is a compute optimized instance in the c6gn series with 64 vCPUs and 128 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
The newer c7gn.16xlarge on AWS Graviton3 is 44% dearer at $3.99/hour.
Within the same generation and size, the c6g.16xlarge on AWS Graviton2 costs $2.18/hour, 21% less ($430 a month). The other variants are the c6a.16xlarge at $2.45, the c6gd.16xlarge at $2.46 and the c6i.16xlarge at $2.72.
Running it in N. Virginia instead of São Paulo saves $1,089 a month per instance: $2.76/hour against $4.26/hour, a 54% spread.
On demand it costs $2.76/hour in US East (N. Virginia), $2,018 a month if left running, which puts it mid-table for compute optimized types at the 31st percentile per vCPU ($0.0432 per vCPU-hour) and the 36th percentile per GiB ($0.0216 per GiB-hour).
Looking beyond its own line, 10 of 28 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the hpc7g.16xlarge on AWS Graviton3 at $1.68/hour.
It is the largest of the 8 c6gn sizes. Dropping to the c6gn.12xlarge saves $505 a month.
Reserving it for a year with no upfront payment cuts the Linux rate to $1.75/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $1.19/hour, 57% below on demand.
