m8idn.8xlarge pricing and specs in US West (Oregon)

32 vCPU · 128 GiB · 50 Gigabit · Intel Xeon Scalable (Granite Rapids)

$3.0550/hour on-demand · $2,230/month (Linux, Shared)

m8idn.8xlarge is a general-purpose EC2 instance with 32 vCPU and 128 GiB, generation 8 of the m family. On-demand it costs $3.0550 an hour, about $2,230 a month if it runs all month. A one-year commitment with nothing up front works out at $1.9247 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $1.1878 an hour, 61% below on-demand. The newer m8g.8xlarge offers the same size for $1.4362 an hour, 53% less and moves to Graviton. Across regions the cheapest place to run m8idn.8xlarge is US East (N. Virginia) (us-east-1) at $3.0550 an hour, 0% below US West (Oregon).

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.
