Analysis
The c8id.12xlarge is a compute optimized instance in the c8id series with 48 vCPUs and 96 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.12xlarge on AWS Graviton4 costs $1.91/hour, 28% less ($545 a month), though switching means rebuilding software for arm64. The other variants are the c8i-flex.12xlarge at $2.14, the c8i.12xlarge at $2.25 and the c8gd.12xlarge at $2.35.
Running it in N. Virginia instead of Sydney saves $607 a month per instance: $2.66/hour against $3.49/hour, a 31% spread. It is not offered in São Paulo, Ireland, London and Singapore, so plan around that if you need a presence there.
On demand it costs $2.66/hour in US East (N. Virginia), $1,943 a month if left running, which puts it mid-table for compute optimized types at the 73rd percentile per vCPU ($0.0554 per vCPU-hour) and the 75th percentile per GiB ($0.0277 per GiB-hour).
Looking beyond its own line, 22 of 30 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the c6g.12xlarge on AWS Graviton2 at $1.63/hour.
It has local instance storage (1 x 2850 GB NVMe SSD), which is fast but lost when the instance stops. Network: 22500 Megabit.
