Amazon EC2 R8gb instances are now generally available

Posted on: Sep 23, 2025

Today, AWS announces the general availability of the new Amazon Elastic Block Storage (Amazon EBS) optimized Amazon Elastic Compute Cloud (Amazon EC2) R8gb instances. These instances are powered by AWS Graviton4 processors to deliver up to 30% better compute performance than AWS Graviton3 processors. At up to 150 Gbps of EBS bandwidth, these instances offer higher EBS performance compared to same-sized equivalent Graviton4-based instances. Take advantage of the higher block storage performance offered by these new EBS optimized EC2 instances to scale the performance and throughput of workloads such as high performance databases and NoSQL databases, while optimizing the cost of running your workloads.

For increased scalability, these instances offer instance sizes up to 24xlarge, including one metal size, up to 768 GiB of memory, up to 150 Gbps of EBS bandwidth, up to 200 Gbps of networking bandwidth. These instances support Elastic Fabric Adapter (EFA) networking on the 16xlarge, 24xlarge, and metal-24xl sizes, which enables lower latency and improved cluster performance for workloads deployed on tightly coupled clusters.

The new R8gb instances are available in US East (N. Virginia) and US West (Oregon) regions. Metal sizes are only available in US East (N. Virginia) region.
