r6idn.16xlarge pricing and specs in EU (Ireland)

64 vCPU · 512 GiB · 100 Gigabit · Intel Xeon 8375C (Ice Lake)

$6.9638/hour on-demand · $5,084/month (Linux, Shared)

r6idn.16xlarge is a memory-optimized EC2 instance with 64 vCPU and 512 GiB, generation 6 of the r family. On-demand it costs $6.9638 an hour, about $5,084 a month if it runs all month. A one-year commitment with nothing up front works out at $4.3872 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 $2.5326 an hour, 64% below on-demand. The newer r6g.16xlarge offers the same size for $3.6096 an hour, 48% less and moves to Graviton. Across regions the cheapest place to run r6idn.16xlarge is US East (N. Virginia) (us-east-1) at $6.2525 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.
