r8g.8xlarge pricing and specs in US East (N. Virginia)

32 vCPU · 256 GiB · 15 Gigabit · AWS Graviton4 Processor Graviton

$1.8851/hour on-demand · $1,376/month (Linux, Shared)

r8g.8xlarge is a memory-optimized EC2 instance with 32 vCPU and 256 GiB, generation 8 of the r family on AWS Graviton (Arm). On-demand it costs $1.8851 an hour, about $1,376 a month if it runs all month. A one-year commitment with nothing up front works out at $1.2470 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 $0.7443 an hour, 61% below on-demand. The newer r9g.8xlarge offers the same size for $2.0547 an hour, 9% more. Across regions the cheapest place to run r8g.8xlarge is Asia Pacific (Mumbai) (ap-south-1) at $1.3213 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.
