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

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

$0.8044/hour on-demand · $587/month (Linux, Shared)

m8i-flex.4xlarge is a general-purpose EC2 instance with 16 vCPU and 64 GiB, generation 8 of the m family. On-demand it costs $0.8044 an hour, about $587 a month if it runs all month. A one-year commitment with nothing up front works out at $0.5321 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 $0.3649 an hour, 55% below on-demand. The newer m8g.4xlarge offers the same size for $0.7181 an hour, 11% less and moves to Graviton.

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.
