Amazon Relational Database Service (Amazon RDS) now supports AWS Graviton2-based X2g database (DB) instances for MySQL, MariaDB, and PostgreSQL databases. X2g DB instances offer double the memory per vCPU compared to R6g/R5 instances and the lowest cost per GiB of memory in Amazon RDS for MySQL, MariaDB, and PostgreSQL databases. The X2g.16xl DB instance has 33% more memory than previously available in Amazon RDS DB instances for MySQL, MariaDB, and PostgreSQL databases and is a great choice for memory-intensive DB workloads.
AWS Graviton2 processors are based on 64-bit Arm Neoverse cores and custom silicon designed by AWS for optimized performance and cost. AWS Graviton2 Processors deliver 7x more performance, 4x more compute cores, 5x faster memory, and 2x larger caches versus first-generation AWS Graviton Processors. Additionally, the AWS Graviton2 processors feature always-on fully encrypted DDR4 memory and 50% faster per core encryption performance.
You can launch new X2g DB instances with a single click in the Amazon RDS Management Console or via a single command in the AWS Command Line Interface (AWS CLI). If you want to upgrade your existing Amazon RDS DB instance to X2g, you can do so on the Modify DB Instance page in the Amazon RDS Management Console or via the AWS CLI. Amazon RDS X2g DB instances are supported on MySQL version 8.0.25 and higher, MariaDB version 10.4.18 and higher, and PostgreSQL version 12.5 and higher. For more details, refer to the Amazon RDS User Guide.
X2g DB instances are available for Amazon RDS in the AWS US East (N. Virginia and Ohio), US West (Oregon), and Europe (Ireland) regions. They are offered in 7 sizes, providing up to 64 vCPUs and 1,024 GiB of memory.
