AWS Graviton2 processors are custom built by Amazon Web Services using 64-bit Arm Neoverse cores and deliver several performance optimizations over first-generation AWS Graviton processors. This includes 7x the performance, 4x the number of compute cores, 2x larger private caches per core, 5x faster memory, and 2x faster floating-point performance per core. Additionally, the AWS Graviton2 processors feature always-on fully encrypted DDR4 memory and 50% faster per core encryption performance. These performance improvements make Graviton2 R6g database instances a great choice for database workloads.
You can launch Graviton2 R6g database instances in the Amazon RDS Management Console or using the AWS CLI. Graviton2 is supported by Aurora MySQL version 2.09.1 and higher, and Aurora PostgreSQL version 11.9 and higher. Upgrading a database instance to Graviton2 requires a simple instance type modification, using the same steps as any other instance modification. Your applications will continue to work as normal and you will not have to port application code. For more details, refer to the Aurora documentation.
The R6g database instances are available in the US East (N. Virginia, Ohio), US West (Oregon), Europe (Ireland, Frankfurt), and Asia Pacific (Mumbai, Singapore, Sydney, Tokyo) regions.
