Analysis
The c8gd.4xlarge is a compute optimized instance in the c8gd series with 16 vCPUs and 32 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.4xlarge on AWS Graviton4 costs $0.6381/hour, 19% less ($106 a month). The other variants are the c8i-flex.4xlarge at $0.7122, the c8i.4xlarge at $0.7497 and the c8a.4xlarge at $0.8622.
Running it in Mumbai instead of São Paulo saves $525 a month per instance: $0.4976/hour against $1.22/hour, a 144% spread.
Compared with the previous generation, it costs 8.0% more than the c7gd.4xlarge on AWS Graviton3 ($42.37 more a month per instance), in exchange for the newer processor. The newer c9gd.4xlarge on AWS Graviton5 is 9.0% dearer at $0.8544/hour.
It has local instance storage (1 x 950 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 15 Gigabit.
Looking beyond its own line, 17 of 31 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the c6g.4xlarge on AWS Graviton2 at $0.5440/hour.
On demand it costs $0.7838/hour in US East (N. Virginia), $572 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).
