r6id.4xlarge pricing and specs in EU (Ireland)

16 vCPU · 128 GiB · Up to 12.5 Gigabit · Intel Xeon 8375C (Ice Lake)

$1.3440/hour on-demand · $981/month (Linux, Shared)

r6id.4xlarge is a memory-optimized EC2 instance with 16 vCPU and 128 GiB, generation 6 of the r family. On-demand it costs $1.3440 an hour, about $981 a month if it runs all month. A one-year commitment with nothing up front works out at $0.8467 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 $0.5053 an hour, 62% below on-demand. The newer r6g.4xlarge offers the same size for $0.9024 an hour, 33% less and moves to Graviton. Across regions the cheapest place to run r6id.4xlarge is US East (N. Virginia) (us-east-1) at $1.2096 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.
