Analysis
The c6gd.16xlarge is a compute optimized instance in the c6gd series with 64 vCPUs and 128 GiB of memory on AWS Graviton2 (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 $1,635 a month per instance: $1.57/hour against $3.81/hour, a 143% spread.
The newer c7gd.16xlarge on AWS Graviton3 is 18% dearer at $2.90/hour.
Within the same generation and size, the c6g.16xlarge on AWS Graviton2 costs $2.18/hour, 11% less ($206 a month). The other variants are the c6a.16xlarge at $2.45, the c6i.16xlarge at $2.72 and the c6gn.16xlarge at $2.76.
At $2.46/hour on demand in US East (N. Virginia), about $1,794 a month, the c6gd.16xlarge is one of the cheaper ways to buy compute optimized capacity: only 11% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0384.
It has local instance storage (2 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.
Looking beyond its own line, 4 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.
It is the largest of the 8 c6gd sizes. Dropping to the c6gd.12xlarge saves $449 a month.
