r8gd.4xlarge pricing and specs in US East (N. Virginia)

16 vCPU · 128 GiB · Up to 15 Gigabit · AWS Graviton4 Processor Graviton

$1.1757/hour on-demand · $858/month (Linux, Shared)

r8gd.4xlarge is a memory-optimized EC2 instance with 16 vCPU and 128 GiB, generation 8 of the r family on AWS Graviton (Arm). On-demand it costs $1.1757 an hour, about $858 a month if it runs all month. A one-year commitment with nothing up front works out at $0.7389 an hour and pays for itself above roughly 458 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.5081 an hour, 57% below on-demand. The newer r8g.4xlarge offers the same size for $0.9426 an hour, 20% less. Across regions the cheapest place to run r8gd.4xlarge is Asia Pacific (Mumbai) (ap-south-1) at $0.7603 an hour, 35% 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.
