Amazon RDS for PostgreSQL, MySQL, and MariaDB expands supports for Graviton3-based M7g and R7g instance types in Amazon Web Services China Regions. M7g and R7g instances are available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. Graviton3-based instances provide up to a 30% performance improvement over Graviton2-based instances on RDS for open-source databases depending on database engine, version, and workload.
Graviton3 processors offer several improvements over the second-generation Graviton processors. Graviton3-based M7g and R7g feature DDR5 memory, which provides 50% more memory bandwidth compared to DDR4, enabling high-speed access to data in memory. M7g and R7g database instances also 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-based M7g and R7g database instances in the Amazon RDS Management Console or using the Amazon CLI. For more details, refer to the RDS documentation.
