i3en.12xlarge pricing and specs in EU (Ireland)

48 vCPU · 384 GiB · 50 Gigabit · Intel Xeon Platinum 8175

$6.0000/hour on-demand · $4,380/month (Linux, Shared)

i3en.12xlarge is a storage-optimized EC2 instance with 48 vCPU and 384 GiB, generation 3 of the i family. On-demand it costs $6.0000 an hour, about $4,380 a month if it runs all month. A one-year commitment with nothing up front works out at $4.0980 an hour and pays for itself above roughly 498 hours a month; below that, on-demand is cheaper. The three-year options go down to $2.2695 an hour, 62% below on-demand. The newer i8g.12xlarge offers the same size for $4.5384 an hour, 24% less and moves to Graviton. Across regions the cheapest place to run i3en.12xlarge is US East (N. Virginia) (us-east-1) at $5.4240 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.

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.
