Analysis
The c6gn.4xlarge is a compute optimized instance in the c6gn series with 16 vCPUs and 32 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.4xlarge on AWS Graviton3 is 44% dearer at $0.9984/hour.
Within the same generation and size, the c6g.4xlarge on AWS Graviton2 costs $0.5440/hour, 21% less ($107 a month). The other variants are the c6a.4xlarge at $0.6120, the c6gd.4xlarge at $0.6144 and the c6i.4xlarge at $0.6800.
Running it in N. Virginia instead of São Paulo saves $272 a month per instance: $0.6912/hour against $1.06/hour, a 54% spread.
On demand it costs $0.6912/hour in US East (N. Virginia), $505 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 31 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the c7g.4xlarge on AWS Graviton3 at $0.5800/hour.
It is size 5 of 8 in the c6gn series. Stepping up to the c6gn.8xlarge gives 32 vCPUs and 64 GiB for $505 more a month. Dropping to the c6gn.2xlarge saves $252 a month.
