r7a.16xlarge pricing and specs in EU (Ireland)
64 vCPU · 512 GiB · 25 Gigabit · AMD EPYC 9R14 Processor
$5.4483/hour on-demand · $3,977/month (Linux, Shared)
r7a.16xlarge is a memory-optimized EC2 instance with 64 vCPU and 512 GiB, generation 7 of the r family. On-demand it costs $5.4483 an hour, about $3,977 a month if it runs all month. A one-year commitment with nothing up front works out at $3.6041 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 $2.1510 an hour, 61% below on-demand. The newer r7g.16xlarge offers the same size for $3.8352 an hour, 30% less and moves to Graviton. Across regions the cheapest place to run r7a.16xlarge is US East (N. Virginia) (us-east-1) at $4.8688 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.

List prices are where it starts. Your bill is where it matters.
TruCost reads your actual AWS usage and tells you which of these commitments you should really buy, what your idle capacity costs, and where every dollar of the bill goes. Thirty minutes on your own data.
