Analysis
The c8gd.16xlarge is a compute optimized instance in the c8gd series with 64 vCPUs and 128 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.16xlarge on AWS Graviton4 costs $2.55/hour, 19% less ($426 a month). The other variants are the c8i-flex.16xlarge at $2.85, the c8i.16xlarge at $3.00 and the c8a.16xlarge at $3.45.
Running it in Mumbai instead of São Paulo saves $2,099 a month per instance: $1.99/hour against $4.87/hour, a 144% spread.
Compared with the previous generation, it costs 8.0% more than the c7gd.16xlarge on AWS Graviton3 ($170 more a month per instance), in exchange for the newer processor. The newer c9gd.16xlarge on AWS Graviton5 is 9.0% dearer at $3.42/hour.
It has local instance storage (2 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 30 Gigabit.
Looking beyond its own line, 16 of 28 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the hpc7g.16xlarge on AWS Graviton3 at $1.68/hour.
On demand it costs $3.14/hour in US East (N. Virginia), $2,289 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).
