m8i-flex.12xlarge pricing and specs in EU (Ireland)

48 vCPU · 192 GiB · Up to 22.5 Gigabit · Intel Xeon Scalable (Granite Rapids)

$2.6897/hour on-demand · $1,963/month (Linux, Shared)

m8i-flex.12xlarge is a general-purpose EC2 instance with 48 vCPU and 192 GiB, generation 8 of the m family. On-demand it costs $2.6897 an hour, about $1,963 a month if it runs all month. A one-year commitment with nothing up front works out at $1.7792 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 $1.2201 an hour, 55% below on-demand. The newer m8g.12xlarge offers the same size for $2.4010 an hour, 11% less and moves to Graviton. Across regions the cheapest place to run m8i-flex.12xlarge is US East (N. Virginia) (us-east-1) at $2.4132 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.

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.
