Introducing Amazon EC2 R8in and R8ib instances

Posted on: Apr 27, 2026

AWS is announcing the general availability of memory optimized Amazon EC2 R8in network optimized instances and Amazon EC2 R8ib EBS optimized instances. These new instances are powered by custom sixth generation Intel Xeon Scalable processors, available only on AWS. These instances also feature the latest sixth generation AWS Nitro cards. M8in and M8ib deliver up to 43% higher performance compared to previous generation M6in and M6ib instances.

R8in instances deliver 600 Gbps network bandwidth, the highest network bandwidth among enhanced networking EC2 instances, and are ideal for workloads such as real-time big data analytics, caching fleets for AI/ML clusters, and distributed web scale in-memory caches.

R8ib instances deliver up to 300Gbps EBS bandwidth, the highest among non-accelerated compute EC2 instances, and are best suited for workloads that benefit from high block storage performance, such as large commercial databases, data lakes, SQL and NoSQL databases, and in-memory databases such as SAP HANA.

Amazon EC2 R8in and Amazon EC2 R8ib instances are available in US East (N. Virginia, Ohio), US West (Oregon), and Europe (Spain) regions, via Savings Plans, On-Demand, and Spot instances. For more information, visit the Amazon EC2 R8i instance page.
