Analysis
The c7g.16xlarge is a compute optimized instance in the c7g series with 64 vCPUs and 128 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $1,448 a month per instance: $1.57/hour against $3.55/hour, a 126% spread.
At $2.32/hour on demand in US East (N. Virginia), about $1,694 a month, the c7g.16xlarge is one of the cheaper ways to buy compute optimized capacity: only 5% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0362.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The c7a.16xlarge on AMD EPYC 9R14 costs 42% more, and the c7i-flex.16xlarge, the c7i.16xlarge and the c7gd.16xlarge also sit above it.
Compared with the previous generation, it costs 6.6% more than the c6g.16xlarge on AWS Graviton2 ($105 more a month per instance), in exchange for the newer processor. The newer c8g.16xlarge on AWS Graviton4 is 10% dearer at $2.55/hour.
It is the largest of the 8 c7g sizes. Dropping to the c7g.12xlarge saves $423 a month.
Looking beyond its own line, 2 of 28 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the hpc7g.16xlarge on AWS Graviton3 at $1.68/hour.
