m8i.4xlarge pricing and specs in US West (Oregon)

16 vCPU · 64 GiB · Up to 15 Gigabit · Intel Xeon Scalable (Granite Rapids)

$0.8467/hour on-demand · $618/month (Linux, Shared)

m8i.4xlarge is a general-purpose EC2 instance with 16 vCPU and 64 GiB, generation 8 of the m family. On-demand it costs $0.8467 an hour, about $618 a month if it runs all month. A one-year commitment with nothing up front works out at $0.5601 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 $0.3841 an hour, 55% below on-demand. The newer m8g.4xlarge offers the same size for $0.7181 an hour, 15% less and moves to Graviton. Across regions the cheapest place to run m8i.4xlarge is US East (N. Virginia) (us-east-1) at $0.8467 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.

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.
