c9g.12xlarge pricing and specs in US East (N. Virginia)
48 vCPU · 96 GiB · 25 Gigabit · AWS Graviton5 Processor Graviton
$2.0866/hour on-demand · $1,523/month (Linux, Shared)
c9g.12xlarge is a compute-optimized EC2 instance with 48 vCPU and 96 GiB, generation 9 of the c family on AWS Graviton (Arm). On-demand it costs $2.0866 an hour, about $1,523 a month if it runs all month. A one-year commitment with nothing up front works out at $1.3750 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 $0.9169 an hour, 56% below on-demand. The newer c9gd.12xlarge offers the same size for $2.5632 an hour, 23% more. Across regions the cheapest place to run c9g.12xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $2.0371 an hour, 2% below US East (N. Virginia).
