Introducing Amazon R6id instances



AWS announces the general availability of new memory-optimized Amazon EC2 R6id instances. R6id instances are powered by 3rd generation Intel Xeon Scalable Ice Lake processors, with an all-core turbo frequency of 3.5 GHz, up to 7.6 TB of local NVMe-based SSD block-level storage, and up to 15% better price performance than R5d instances. Furthermore, R6id instances also offer up to 58% higher TB storage per vCPU and 34% lower cost per TB and come with always-on memory encryption using Intel Total Memory Encryption (TME). R6id instances are ideal for memory-intensive workloads, distributed web-scale in-memory caches, in-memory databases, and real-time big data analytics. They will also benefit applications that need temporary data storage, such as caches and scratch files. To provide increased scalability, R6id instances offer a new 32xlarge size that has 33% more vCPU and memory than previous generation instances and up to 20% higher memory bandwidth per vCPU; the 32xlarge size also integrates with the [Elastic Fabric Adapter](/hpc/efa/), which enables low latency and highly scalable inter-node communication. R6id instances also provide up to 50 Gbps of networking speed and 40 Gbps of bandwidth to the [Amazon Elastic Block Store (EBS)](/ebs/). These instances are generally available today in the US East (Ohio), US East (N. Virginia), US West (Oregon), and Europe (Ireland) [Regions](/about-aws/global-infrastructure/regional-product-services/). To get started, visit the [AWS Management Console,]( [AWS Command Line Interface (CLI)](/cli/), and [AWS SDKs]( To learn more, visit the [R6i instance pages](/ec2/instance-types/r6i/).
