Analysis
The c8gn.2xlarge is a compute optimized instance in the c8gn series with 8 vCPUs and 16 GiB of memory on AWS Graviton4 (up to 2.8 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c8g.2xlarge on AWS Graviton4 costs $0.3190/hour, 33% less ($113 a month). The other variants are the c8i-flex.2xlarge at $0.3561, the c8i.2xlarge at $0.3748 and the c8gd.2xlarge at $0.3919.
Per vCPU it is one of the dearer compute optimized types: 82% of the 291 current types in the family cost less than its $0.0592 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $0.4740/hour in US East (N. Virginia), or $346 for a 730-hour month.
Running it in Mumbai instead of São Paulo saves $186 a month per instance: $0.4740/hour against $0.7286/hour, a 54% spread.
Looking beyond its own line, 25 of 31 current types with 8 vCPUs and similar memory are cheaper. The cheapest of those is the c6g.2xlarge on AWS Graviton2 at $0.2720/hour.
It is 5.0% cheaper than the older c7gn.2xlarge on AWS Graviton3, so staying on the previous generation costs more as well as being slower.
