Analysis
The c6in.12xlarge is a compute optimized instance in the c6in series with 48 vCPUs and 96 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c6g.12xlarge on AWS Graviton2 costs $1.63/hour, 40% less ($795 a month), though switching means rebuilding software for arm64. The other variants are the c6a.12xlarge at $1.84, the c6gd.12xlarge at $1.84 and the c6i.12xlarge at $2.04.
Per vCPU it is one of the dearer compute optimized types: 78% of the 291 current types in the family cost less than its $0.0567 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $2.72/hour in US East (N. Virginia), or $1,987 for a 730-hour month.
Running it in Mumbai instead of São Paulo saves $1,067 a month per instance: $2.72/hour against $4.18/hour, a 54% spread.
Looking beyond its own line, 23 of 30 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the c7g.12xlarge on AWS Graviton3 at $1.74/hour.
It is size 6 of 9 in the c6in series. Stepping up to the c6in.16xlarge gives 64 vCPUs and 128 GiB for $662 more a month. Dropping to the c6in.8xlarge saves $662 a month.
