c9g.4xlarge pricing and specs in US East (N. Virginia)
16 vCPU · 32 GiB · Up to 17 Gigabit · AWS Graviton5 Processor Graviton
$0.6955/hour on-demand · $508/month (Linux, Shared)
c9g.4xlarge is a compute-optimized EC2 instance with 16 vCPU and 32 GiB, generation 9 of the c family on AWS Graviton (Arm). On-demand it costs $0.6955 an hour, about $508 a month if it runs all month. A one-year commitment with nothing up front works out at $0.4583 an hour and pays for itself above roughly 481 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.3056 an hour, 56% below on-demand. The newer c9gd.4xlarge offers the same size for $0.8544 an hour, 23% more. Across regions the cheapest place to run c9g.4xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $0.6790 an hour, 2% below US East (N. Virginia).

Newer generations of the same size
Same family letter and size in a newer generation, ranked by price. “vCPU per $” uses vCPU as the performance proxy — newer chips usually add more, so it is a floor.
