c8ib.16xlarge pricing and specs in US East (N. Virginia)
64 vCPU · 128 GiB · 66.66 Gigabit · Intel Xeon Scalable (Granite Rapids)
$4.3546/hour on-demand · $3,179/month (Linux, Shared)
c8ib.16xlarge is a compute-optimized EC2 instance with 64 vCPU and 128 GiB, generation 8 of the c family. On-demand it costs $4.3546 an hour, about $3,179 a month if it runs all month. A one-year commitment with nothing up front works out at $2.7434 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 $1.5811 an hour, 64% below on-demand. The newer c8g.16xlarge offers the same size for $2.5523 an hour, 41% less and moves to Graviton. US East (N. Virginia) is already the cheapest region for c8ib.16xlarge.
