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.
