m8i.12xlarge pricing and specs in US East (N. Virginia)

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

$2.5402/hour on-demand · $1,854/month (Linux, Shared)

m8i.12xlarge is a general-purpose EC2 instance with 48 vCPU and 192 GiB, generation 8 of the m family. On-demand it costs $2.5402 an hour, about $1,854 a month if it runs all month. A one-year commitment with nothing up front works out at $1.6803 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 $1.1522 an hour, 55% below on-demand. The newer m8g.12xlarge offers the same size for $2.1542 an hour, 15% less and moves to Graviton. US East (N. Virginia) is already the cheapest region for m8i.12xlarge.

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.
