r7i.8xlarge pricing and specs in EU (Ireland)

32 vCPU · 256 GiB · 12.5 Gigabit · Intel Xeon Scalable (Sapphire Rapids)

$2.3688/hour on-demand · $1,729/month (Linux, Shared)

r7i.8xlarge is a memory-optimized EC2 instance with 32 vCPU and 256 GiB, generation 7 of the r family. On-demand it costs $2.3688 an hour, about $1,729 a month if it runs all month. A one-year commitment with nothing up front works out at $1.5670 an hour and pays for itself above roughly 482 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.9352 an hour, 61% below on-demand. The newer r7g.8xlarge offers the same size for $1.9176 an hour, 19% less and moves to Graviton. Across regions the cheapest place to run r7i.8xlarge is US East (N. Virginia) (us-east-1) at $2.1168 an hour, 11% 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.
