c8gn.4xlarge pricing and specs in EU (Ireland)

16 vCPU · 32 GiB · 50 Gigabit · AWS Graviton4 Processor Graviton

$1.0709/hour on-demand · $782/month (Linux, Shared)

c8gn.4xlarge is a compute-optimized EC2 instance with 16 vCPU and 32 GiB, generation 8 of the c family on AWS Graviton (Arm). On-demand it costs $1.0709 an hour, about $782 a month if it runs all month. A one-year commitment with nothing up front works out at $0.6747 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.4487 an hour, 58% below on-demand. The newer c8g.4xlarge offers the same size for $0.6822 an hour, 36% less. Across regions the cheapest place to run c8gn.4xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $0.9253 an hour, 14% below EU (Ireland).

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.

Public AWS list prices (USD), refreshed nightly (catalog 2026-10-21). RI and Savings Plan rates are effective hourly (upfront amortised over the term) and are charged for every hour of the term.

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.
