r8idn.32xlarge pricing and specs in EU (Ireland)
128 vCPU · 1024 GiB · 200 Gigabit · Intel Xeon Scalable (Granite Rapids)
$16.7130/hour on-demand · $12,200/month (Linux, Shared)
r8idn.32xlarge is a memory-optimized EC2 instance with 128 vCPU and 1024 GiB, generation 8 of the r family. On-demand it costs $16.7130 an hour, about $12,200 a month if it runs all month. A one-year commitment with nothing up front works out at $10.5292 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 $6.9835 an hour, 58% below on-demand. The newer r8i.32xlarge offers the same size for $9.9488 an hour, 40% less. Across regions the cheapest place to run r8idn.32xlarge is US East (N. Virginia) (us-east-1) at $15.0061 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.
