Analysis
The c7g.12xlarge is a compute optimized instance in the c7g series with 48 vCPUs and 96 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 $1,086 a month per instance: $1.18/hour against $2.67/hour, a 126% spread.
At $1.74/hour on demand in US East (N. Virginia), about $1,270 a month, the c7g.12xlarge 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.12xlarge on AMD EPYC 9R14 costs 42% more, and the c7i-flex.12xlarge, the c7i.12xlarge and the c7gd.12xlarge also sit above it.
Compared with the previous generation, it costs 6.6% more than the c6g.12xlarge on AWS Graviton2 ($78.84 more a month per instance), in exchange for the newer processor. The newer c8g.12xlarge on AWS Graviton4 is 10% dearer at $1.91/hour.
It is size 7 of 8 in the c7g series. Stepping up to the c7g.16xlarge gives 64 vCPUs and 128 GiB for $423 more a month. Dropping to the c7g.8xlarge saves $423 a month.
