c7gn.2xlarge

Analysis

The c7gn.2xlarge is a compute optimized instance in the c7gn series with 8 vCPUs and 16 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.2xlarge on AWS Graviton3 costs $0.2900/hour, 42% less ($153 a month). The other variants are the c7i-flex.2xlarge at $0.3392, the c7i.2xlarge at $0.3570 and the c7gd.2xlarge at $0.3629.

Compared with the previous generation, it costs 44% more than the c6gn.2xlarge on AWS Graviton2 ($112 more a month per instance), in exchange for the newer processor. The newer c8gn.2xlarge on AWS Graviton4 is 5.0% cheaper at $0.4740/hour, which makes the c7gn.2xlarge hard to justify for new deployments.

Running it in N. Virginia instead of Tokyo saves $95.19 a month per instance: $0.4992/hour against $0.6296/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: 87% 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 $0.4992/hour in US East (N. Virginia), or $364 for a 730-hour month.
