64 vCPU · 128 GiB · 200 Gigabit · AWS Graviton4 Processor Graviton

$3.7920/hour on-demand · $2,768/month (Linux, Shared)

c8gn.16xlarge is a compute-optimized EC2 instance with 64 vCPU and 128 GiB, generation 8 of the c family on AWS Graviton (Arm). On-demand it costs $3.7920 an hour, about $2,768 a month if it runs all month. A one-year commitment with nothing up front works out at $2.3890 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $1.3769 an hour, 64% below on-demand. The newer c8g.16xlarge offers the same size for $2.5523 an hour, 33% less. Across regions the cheapest place to run c8gn.16xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $3.7011 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.

Caveat: instance price is only part of the bill. Cross-region and internet data transfer, latency to your users, data-residency rules and service availability can outweigh a few percent on compute.
