Analysis
The c8i.32xlarge is a compute optimized instance in the c8i series with 128 vCPUs and 256 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
It is the cheapest of the 4 processor variants AWS sells at this size and generation. The c8ib.32xlarge on Intel Xeon Scalable (Granite Rapids) costs 45% more, and the c8id.32xlarge and the c8in.32xlarge also sit above it.
Running it in Mumbai instead of São Paulo saves $2,370 a month per instance: $6.00/hour against $9.24/hour, a 54% spread.
Windows Server roughly doubles the bill at $11.89/hour, because the licence is charged per vCPU.
On demand it costs $6.00/hour in US East (N. Virginia), $4,378 a month if left running, which puts it mid-table for compute optimized types at the 47th percentile per vCPU ($0.0469 per vCPU-hour) and the 50th percentile per GiB ($0.0234 per GiB-hour).
Looking beyond its own line, 2 of 9 current types with 128 vCPUs and similar memory are cheaper. The cheapest of those is the c6a.32xlarge on AMD EPYC 7R13 at $4.90/hour.
It is size 9 of 11 in the c8i series. Stepping up to the c8i.48xlarge gives 192 vCPUs and 384 GiB for $2,189 more a month. Dropping to the c8i.24xlarge saves $1,095 a month.
