Analysis
The c8gd.12xlarge is a compute optimized instance in the c8gd series with 48 vCPUs and 96 GiB of memory on AWS Graviton4 (up to 2.7 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, 19% less ($319 a month). The other variants are the c8i-flex.12xlarge at $2.14, the c8i.12xlarge at $2.25 and the c8a.12xlarge at $2.59.
Running it in Mumbai instead of São Paulo saves $1,574 a month per instance: $1.49/hour against $3.65/hour, a 144% spread.
Compared with the previous generation, it costs 8.0% more than the c7gd.12xlarge on AWS Graviton3 ($127 more a month per instance), in exchange for the newer processor. The newer c9gd.12xlarge on AWS Graviton5 is 9.0% dearer at $2.56/hour.
It has local instance storage (3 x 950 GB NVMe SSD), which is fast but lost when the instance stops. Network: 22500 Megabit.
Looking beyond its own line, 17 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.
On demand it costs $2.35/hour in US East (N. Virginia), $1,717 a month if left running, which puts it mid-table for compute optimized types at the 53rd percentile per vCPU ($0.0490 per vCPU-hour) and the 57th percentile per GiB ($0.0245 per GiB-hour).
