16 vCPU · 64 GiB · Up to 33.33 Gigabit · Intel Xeon Scalable (Granite Rapids)

$1.5275/hour on-demand · $1,115/month (Linux, Shared)

m8idb.4xlarge is a general-purpose EC2 instance with 16 vCPU and 64 GiB, generation 8 of the m family. On-demand it costs $1.5275 an hour, about $1,115 a month if it runs all month. A one-year commitment with nothing up front works out at $0.9623 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper.

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.
