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.
