64 vCPU · 512 GiB · 30 Gigabit · AWS Graviton4 Processor Graviton

$3.7702/hour on-demand · $2,752/month (Linux, Shared)

r8g.16xlarge is a memory-optimized EC2 instance with 64 vCPU and 512 GiB, generation 8 of the r family on AWS Graviton (Arm). On-demand it costs $3.7702 an hour, about $2,752 a month if it runs all month. A one-year commitment with nothing up front works out at $2.4940 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 $1.4885 an hour, 61% below on-demand. The newer r9g.16xlarge offers the same size for $4.1094 an hour, 9% more. Across regions the cheapest place to run r8g.16xlarge is Asia Pacific (Mumbai) (ap-south-1) at $2.6426 an hour, 30% 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.
