r8idb.24xlarge pricing and specs in US East (N. Virginia)

96 vCPU · 768 GiB · 100 Gigabit · Intel Xeon Scalable (Granite Rapids)

$11.2546/hour on-demand · $8,216/month (Linux, Shared)

r8idb.24xlarge is a memory-optimized EC2 instance with 96 vCPU and 768 GiB, generation 8 of the r family. On-demand it costs $11.2546 an hour, about $8,216 a month if it runs all month. A one-year commitment with nothing up front works out at $7.0904 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 $4.5824 an hour, 59% below on-demand. The newer r8g.24xlarge offers the same size for $5.6554 an hour, 50% less and moves to Graviton. US East (N. Virginia) is already the cheapest region for r8idb.24xlarge.

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.
