m8a.4xlarge pricing and specs in US East (N. Virginia)

16 vCPU · 64 GiB · Up to 15 Gigabit · AMD EPYC 9R45 Processor

$0.9738/hour on-demand · $711/month (Linux, Shared)

m8a.4xlarge is a general-purpose EC2 instance with 16 vCPU and 64 GiB, generation 8 of the m family. On-demand it costs $0.9738 an hour, about $711 a month if it runs all month. A one-year commitment with nothing up front works out at $0.6441 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 $0.4417 an hour, 55% below on-demand. The newer m8g.4xlarge offers the same size for $0.7181 an hour, 26% less and moves to Graviton. US East (N. Virginia) is already the cheapest region for m8a.4xlarge.

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.
