Analysis
The c7gn.12xlarge is a compute optimized instance in the c7gn series with 48 vCPUs and 96 GiB of memory on AWS Graviton3 (up to 2.6 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c7g.12xlarge on AWS Graviton3 costs $1.74/hour, 42% less ($916 a month). The other variants are the c7i-flex.12xlarge at $2.03, the c7i.12xlarge at $2.14 and the c7gd.12xlarge at $2.18.
Compared with the previous generation, it costs 44% more than the c6gn.12xlarge on AWS Graviton2 ($673 more a month per instance), in exchange for the newer processor. The newer c8gn.12xlarge on AWS Graviton4 is 5.0% cheaper at $2.84/hour, which makes the c7gn.12xlarge hard to justify for new deployments.
Running it in N. Virginia instead of Tokyo saves $571 a month per instance: $3.00/hour against $3.78/hour, a 26% spread. It is not offered in Canada Central, São Paulo, Frankfurt, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.
Per vCPU it is one of the dearer compute optimized types: 89% of the 291 current types in the family cost less than its $0.0624 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $3.00/hour in US East (N. Virginia), or $2,186 for a 730-hour month.
