Amazon ElastiCache now supports the next generation general-purpose and memory-optimized Amazon EC2 M5 and R5 nodes for high-performance applications. Both M5 and R5 nodes are based on the AWS Nitro System and feature Enhanced Networking based on Elastic Network Adapter (ENA), to deliver up to 25 Gbps of aggregate network bandwidth. M5 and R5 nodes are powered by custom Intel® Xeon Scalable processors with a sustained all core frequency of up to 3.1 GHz. These processors also feature Intel’s newest vector processing instruction set, Advanced Vector Extension 512 (AVX-512), for faster processing of high-performance workloads. The general-purpose M5 nodes offer memory size flexibility ranging from 6.38 GiB to 314.32 GiB. The memory optimized R5 nodes offer memory size flexibility of 13.07 GiB to 635.61 GiB.
