Per hour on Linux/UNIX, 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.

The R8a instance family, generally available since November 4, 2025, features 5th Gen AMD EPYC processors (formerly code named "Turin") with a maximum frequency of 4.5 GHz. These memory-optimized instances offer up to 75 Gbps of network bandwidth and up to 60 Gbps EBS bandwidth. R8a instances are EBS-only and built on the AWS Nitro System and sixth-generation Nitro Cards. They are ideal for high-performance, memory-intensive workloads.
