AWS Graviton3-based R7g database instances are now generally available for Amazon Aurora with PostgreSQL compatibility and Amazon Aurora with MySQL compatibility in US East (N. Virginia, Ohio), US West (Oregon), and Europe (Ireland) regions. Graviton3 instances provide up to 30% performance improvement and up to 20% price-performance improvement over Graviton2 instances for Aurora depending on database engine, version, and workload.
AWS Graviton3 processors are the latest generation of custom-designed AWS Graviton processors built on the AWS Nitro System. The Graviton3 processors offer several improvements over the second-generation Graviton processors. Graviton3-based R7g are the first AWS database instances to feature the latest DDR5 memory, which provides 50% more memory bandwidth compared to DDR4, enabling high-speed access to data in memory. R7g database instances offer up to 30Gbps enhanced networking bandwidth and up to 20 Gbps of bandwidth to the Amazon Elastic Block Store (Amazon EBS).
You can spin up Graviton3 R7g database instances in the Amazon RDS Management Console or using the AWS CLI. Graviton3is supported by Aurora MySQL version 3.03.1 and higher, and Aurora PostgreSQL version 13.10 and higher, Aurora PostgreSQL 14.7 and higher, and Aurora PostgreSQL 15.2 and higher. Upgrading a database instance to Graviton3 requires a simple instance type modification. For more details, refer to the Aurora documentation.
Amazon Aurora is designed for unparalleled high performance and availability at global scale with full MySQL and PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.
