Analysis
The c6gn.8xlarge is a compute optimized instance in the c6gn series with 32 vCPUs and 64 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.8xlarge on AWS Graviton3 is 44% dearer at $2.00/hour.
Within the same generation and size, the c6g.8xlarge on AWS Graviton2 costs $1.09/hour, 21% less ($215 a month). The other variants are the c6a.8xlarge at $1.22, the c6gd.8xlarge at $1.23 and the c6i.8xlarge at $1.36.
Running it in N. Virginia instead of São Paulo saves $544 a month per instance: $1.38/hour against $2.13/hour, a 54% spread.
On demand it costs $1.38/hour in US East (N. Virginia), $1,009 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, 9 of 28 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the c7g.8xlarge on AWS Graviton3 at $1.16/hour.
It is size 6 of 8 in the c6gn series. Stepping up to the c6gn.12xlarge gives 48 vCPUs and 96 GiB for $505 more a month. Dropping to the c6gn.4xlarge saves $505 a month.
