r8i.xlarge pricing and specs in EU (Ireland)

4 vCPU · 32 GiB · Up to 12.5 Gigabit · Intel Xeon Scalable (Granite Rapids)

$0.3109/hour on-demand · $227/month (Linux, Shared)

r8i.xlarge is a memory-optimized EC2 instance with 4 vCPU and 32 GiB, generation 8 of the r family. On-demand it costs $0.3109 an hour, about $227 a month if it runs all month. A one-year commitment with nothing up front works out at $0.2057 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 $0.1410 an hour, 55% below on-demand. The newer r8g.xlarge offers the same size for $0.2637 an hour, 15% less and moves to Graviton. Across regions the cheapest place to run r8i.xlarge is US East (N. Virginia) (us-east-1) at $0.2778 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.
