$4.1094/hour on-demand · $3,000/month (Linux, Shared)

r9g.16xlarge is a memory-optimized EC2 instance with 64 vCPU and 512 GiB, generation 9 of the r family on AWS Graviton (Arm). On-demand it costs $4.1094 an hour, about $3,000 a month if it runs all month. A one-year commitment with nothing up front works out at $2.7184 an hour and pays for itself above roughly 482 hours a month; below that, on-demand is cheaper. The three-year options go down to $1.8640 an hour, 55% below on-demand. The newer r9gd.16xlarge offers the same size for $5.1258 an hour, 25% more. US East (N.

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.
