r5.16xlarge pricing and specs in EU (Ireland)

64 vCPU · 512 GiB · 20 Gigabit · Intel Xeon Platinum 8175 previous generation

$4.5120/hour on-demand · $3,294/month (Linux, Shared)

r5.16xlarge is a memory-optimized EC2 instance with 64 vCPU and 512 GiB, generation 5 of the r family; AWS lists it as a previous generation. On-demand it costs $4.5120 an hour, about $3,294 a month if it runs all month. A one-year commitment with nothing up front works out at $2.8430 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 $1.6965 an hour, 62% below on-demand. The newer r6g.16xlarge offers the same size for $3.6096 an hour, 20% less and moves to Graviton. Across regions the cheapest place to run r5.16xlarge is US East (N. Virginia) (us-east-1) at $4.0320 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.
