r8i.48xlarge pricing and specs in EU (Ireland)
192 vCPU · 1536 GiB · 75 Gigabit · Intel Xeon Scalable (Granite Rapids)
$14.9232/hour on-demand · $10,894/month (Linux, Shared)
r8i.48xlarge is a memory-optimized EC2 instance with 192 vCPU and 1536 GiB, generation 8 of the r family. On-demand it costs $14.9232 an hour, about $10,894 a month if it runs all month. A one-year commitment with nothing up front works out at $9.8717 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 $6.7692 an hour, 55% below on-demand. The newer r8g.48xlarge offers the same size for $12.6566 an hour, 15% less and moves to Graviton. Across regions the cheapest place to run r8i.48xlarge is US East (N. Virginia) (us-east-1) at $13.3363 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.
