c8gn.16xlarge pricing and specs in EU (Ireland)

64 vCPU · 128 GiB · 200 Gigabit · AWS Graviton4 Processor Graviton

$4.2835/hour on-demand · $3,127/month (Linux, Shared)

c8gn.16xlarge is a compute-optimized EC2 instance with 64 vCPU and 128 GiB, generation 8 of the c family on AWS Graviton (Arm). On-demand it costs $4.2835 an hour, about $3,127 a month if it runs all month. A one-year commitment with nothing up front works out at $2.6986 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 $1.7950 an hour, 58% below on-demand. The newer c8g.16xlarge offers the same size for $2.7290 an hour, 36% less. Across regions the cheapest place to run c8gn.16xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $3.7011 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.
