Analysis
The c8gb.xlarge is a compute optimized instance in the c8gb series with 4 vCPUs and 8 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.xlarge on AWS Graviton4 costs $0.1595/hour, 33% less ($56.56 a month). The other variants are the c8i-flex.xlarge at $0.1780, the c8i.xlarge at $0.1874 and the c8gd.xlarge at $0.1960.
Running it in N. Virginia instead of Frankfurt saves $24.03 a month per instance: $0.2370/hour against $0.2699/hour, a 14% spread. It is not offered in Canada Central, São Paulo, London, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.
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 $0.2370/hour in US East (N. Virginia), or $173 for a 730-hour month.
Looking beyond its own line, 25 of 31 current types with 4 vCPUs and similar memory are cheaper. The cheapest of those is the c6g.xlarge on AWS Graviton2 at $0.1360/hour.
