• Graviton2 processors feature always-on fully encrypted DDR4 memory and are 50% faster per core encryption performance.
• AWS RDS Graviton2 instances provide up to 52% price/performance improvement for RDS open-source databases depending on the database engine, version, and workload. They also provide up to 35% price/performance improvement for Aurora depending on database size.
• AWS Elasticache Gravitron2 instances provide up to 45% price/performance improvement over previous generation instances.
• AWS Elasticsearch Service Graviton2 instances provide up to 44% price/performance improvement over previous generation instances.
