64 vCPU · 128 GiB · 25 Gigabit · AWS Graviton2 Processor Graviton

$2.1760/hour on-demand · $1,588/month (Linux, Shared)

c6g.16xlarge is a compute-optimized EC2 instance with 64 vCPU and 128 GiB, generation 6 of the c family on AWS Graviton (Arm). On-demand it costs $2.1760 an hour, about $1,588 a month if it runs all month. A one-year commitment with nothing up front works out at $1.3709 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 $0.8182 an hour, 62% below on-demand. The newer c7g.16xlarge offers the same size for $2.3200 an hour, 7% more. Across regions the cheapest place to run c6g.16xlarge is Asia Pacific (Mumbai) (ap-south-1) at $1.3632 an hour, 37% below US West (Oregon).

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.
