Analysis
The c6gn.12xlarge is a compute optimized instance in the c6gn series with 48 vCPUs and 96 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.12xlarge on AWS Graviton3 is 44% dearer at $3.00/hour.
Within the same generation and size, the c6g.12xlarge on AWS Graviton2 costs $1.63/hour, 21% less ($322 a month). The other variants are the c6a.12xlarge at $1.84, the c6gd.12xlarge at $1.84 and the c6i.12xlarge at $2.04.
Running it in N. Virginia instead of São Paulo saves $816 a month per instance: $2.07/hour against $3.19/hour, a 54% spread.
On demand it costs $2.07/hour in US East (N. Virginia), $1,514 a month if left running, which puts it mid-table for compute optimized types at the 30th percentile per vCPU ($0.0432 per vCPU-hour) and the 34th percentile per GiB ($0.0216 per GiB-hour).
Looking beyond its own line, 10 of 30 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the c7g.12xlarge on AWS Graviton3 at $1.74/hour.
It is size 7 of 8 in the c6gn series. Stepping up to the c6gn.16xlarge gives 64 vCPUs and 128 GiB for $505 more a month. Dropping to the c6gn.8xlarge saves $505 a month.
