AWS introduced R8in, R8idn, R8ib, and R8idb Amazon EC2 instance types to the Tokyo and European (Frankfurt, Ireland) regions in mid-2026. These instances, featuring custom sixth generation Intel Xeon Scalable processors and sixth generation AWS Nitro cards, yield up to 43% better compute performance per vCPU compared to prior R6in and R6idn instances. Specific configurations prioritize network bandwidth or EBS throughput, with R8in and R8idn providing up to 600 Gbps network bandwidth and R8ib and R8idb offering up to 300 Gbps EBS bandwidth, suitable for diverse workloads including real-time analytics and storage-intensive databases.
Complementing raw performance, these instances support Elastic Fabric Adapter (EFA) networking on large sizes, enabling lower latency and enhanced cluster performance for tightly coupled workloads such as AI/ML. Availability extends beyond Asia Pacific and Europe to multiple US regions, with flexible purchasing options including Savings Plans and Spot Instances. The varied instance types offer optimized choices for network-intensive, storage-intensive, and general-purpose applications, according to AWS documentation, though third-party verification of performance claims remains pending.
