Introducing Amazon EC2 R7iz instances



Today, AWS announces the general availability of memory-optimized, high CPU performance Amazon Elastic Cloud Compute (Amazon EC2) R7iz instances. R7iz instances are the fastest 4th generation Intel Xeon Scalable-based (Sapphire Rapids) instances in the cloud with 3.9 GHz sustained all-core turbo frequency. They deliver up to 20% better performance than previous generation z1d instances. These instances are built on the [AWS Nitro System]( The Nitro System is a collection of AWS-designed hardware and software innovations that enables the delivery of efficient and flexible cloud services with enhanced security, isolated multi-tenancy, private networking, and fast local storage. R7iz instances are ideal for front-end Electronic Design Automation (EDA), relational databases with high per-core licensing fees, financial, actuarial, data analytics simulations, and other workloads requiring a combination of high compute performance and high memory footprint. For increased memory and scalability, R7iz instances are available in eight sizes, with up to 128 vCPUs and up to 1,024 GiB of memory. R7iz instances use DDR5 memory and deliver up to 2.4x higher memory bandwidth than comparable high-frequency instances. They also deliver up to 50 Gbps of networking speed and 40 Gbps of Amazon Elastic Block Store (EBS) bandwidth. All of these instances are available in the following [AWS Regions]( US East (N. Virginia), and US West (Oregon). To learn more, see [Amazon EC2 R7iz instances]( To get started, see [AWS Management Console](, [AWS Command Line Interface (AWS CLI)](, and [AWS SDKs](
