r8idb.96xlarge pricing and specs in EU (Ireland)

384 vCPU · 3072 GiB · 400 Gigabit · Intel Xeon Scalable (Granite Rapids)

$50.1389/hour on-demand · $36,601/month (Linux, Shared)

r8idb.96xlarge is a memory-optimized EC2 instance with 384 vCPU and 3072 GiB, generation 8 of the r family. On-demand it costs $50.1389 an hour, about $36,601 a month if it runs all month. A one-year commitment with nothing up front works out at $31.5875 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 $20.9506 an hour, 58% below on-demand. The newer r8i.96xlarge offers the same size for $29.8464 an hour, 40% less. Across regions the cheapest place to run r8idb.96xlarge is US East (N. Virginia) (us-east-1) at $45.0182 an hour, 10% below EU (Ireland).

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.
