c8i-flex.8xlarge pricing and specs in US West (Oregon)

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

$1.4243/hour on-demand · $1,040/month (Linux, Shared)

c8i-flex.8xlarge is a compute-optimized EC2 instance with 32 vCPU and 64 GiB, generation 8 of the c family. On-demand it costs $1.4243 an hour, about $1,040 a month if it runs all month. A one-year commitment with nothing up front works out at $0.9422 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 $0.6271 an hour, 56% below on-demand. The newer c8g.8xlarge offers the same size for $1.2762 an hour, 10% less and moves to Graviton. Across regions the cheapest place to run c8i-flex.8xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $1.3960 an hour, 2% 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.
