r8idb.32xlarge pricing and specs in EU (Ireland)

128 vCPU · 1024 GiB · 133.33 Gigabit · Intel Xeon Scalable (Granite Rapids)

$16.7130/hour on-demand · $12,200/month (Linux, Shared)

r8idb.32xlarge is a memory-optimized EC2 instance with 128 vCPU and 1024 GiB, generation 8 of the r family. On-demand it costs $16.7130 an hour, about $12,200 a month if it runs all month. A one-year commitment with nothing up front works out at $10.5292 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 $6.9835 an hour, 58% below on-demand. The newer r8i.32xlarge offers the same size for $9.9488 an hour, 40% less. Across regions the cheapest place to run r8idb.32xlarge is US East (N. Virginia) (us-east-1) at $15.0061 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.

Public AWS list prices (USD), refreshed nightly (catalog 2026-10-22). RI and Savings Plan rates are effective hourly (upfront amortised over the term) and are charged for every hour of the term.

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.
