i4i.12xlarge pricing and specs in EU (Ireland)

48 vCPU · 384 GiB · 28.12 Gigabit · Intel Xeon 8375C (Ice Lake)

$4.5410/hour on-demand · $3,315/month (Linux, Shared)

i4i.12xlarge is a storage-optimized EC2 instance with 48 vCPU and 384 GiB, generation 4 of the i family. On-demand it costs $4.5410 an hour, about $3,315 a month if it runs all month. A one-year commitment with nothing up front works out at $2.9610 an hour and pays for itself above roughly 476 hours a month; below that, on-demand is cheaper. The three-year options go down to $1.8240 an hour, 60% below on-demand. The newer i8g.12xlarge offers the same size for $4.5384 an hour, 0% less and moves to Graviton. Across regions the cheapest place to run i4i.12xlarge is US East (N. Virginia) (us-east-1) at $4.1180 an hour, 9% 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.

Public AWS list prices (USD), refreshed nightly (catalog 2026-10-22). RI and Savings Plan rates are effective hourly (upfront amortised over the term) and are charged for every hour of the term.

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.
