Analysis
The c8i.48xlarge is a compute optimized instance in the c8i series with 192 vCPUs and 384 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.
Within the same generation and size, the c8g.48xlarge on AWS Graviton4 costs $7.66/hour, 15% less ($978 a month), though switching means rebuilding software for arm64. The other variants are the c8gd.48xlarge at $9.41, the c8a.48xlarge at $10.35 and the c8id.48xlarge at $10.64.
Running it in Mumbai instead of São Paulo saves $3,554 a month per instance: $9.00/hour against $13.87/hour, a 54% spread.
Windows Server roughly doubles the bill at $17.83/hour, because the licence is charged per vCPU.
On demand it costs $9.00/hour in US East (N. Virginia), $6,567 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).
Compared with the previous generation, it costs 5.0% more than the c7i.48xlarge on Intel Xeon Scalable (Sapphire Rapids) ($313 more a month per instance), in exchange for the newer processor.
Looking beyond its own line, 4 of 14 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the c6a.48xlarge on AMD EPYC 7R13 at $7.34/hour.
