Per hour on Windows, in each type's cheapest region. Typical spot: per pricing run of the last 7 days, the cheapest zone's spot price, averaged, as the finder shows it with that region selected. On-demand: the same region's price. Per vCPU-hour: the spot price, or without spot the on-demand price, per vCPU. Every region is under Prices by region.
Description #
The C5AD instance family, generally available since August 2020, is powered by 2nd generation AMD EPYC 7R32 processors clocked up to 3.3 GHz, offering a cost-effective x86 compute-optimized solution. These instances feature fast, local NVMe-based SSD instance storage for high-speed, low-latency access to temporary data, a key differentiator from the C5A family. Built on the AWS Nitro System, they leverage the Elastic Network Adapter (ENA) to provide up to 20 Gbps of network bandwidth. This family is ideal for workloads like video encoding, gaming, and high-performance web servers.
