16 vCPU · 128 GiB · Up to 15 Gigabit · Intel Xeon Scalable (Granite Rapids)

$1.3957/hour on-demand · $1,019/month (Linux, Shared)

r8id.4xlarge is a memory-optimized EC2 instance with 16 vCPU and 128 GiB, generation 8 of the r family. On-demand it costs $1.3957 an hour, about $1,019 a month if it runs all month. A one-year commitment with nothing up front works out at $0.8793 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 $0.6029 an hour, 57% below on-demand. The newer r8g.4xlarge offers the same size for $0.6606 an hour, 53% less and moves to Graviton. Across regions the cheapest place to run r8id.4xlarge is US East (N. Virginia) (us-east-1) at $1.3306 an hour, 5% below Asia Pacific (Mumbai).

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.

List prices are where it starts. Your bill is where it matters.

TruCost reads your actual AWS usage and tells you which of these commitments you should really buy, what your idle capacity costs, and where every dollar of the bill goes. Thirty minutes on your own data.
