Services
Starting today, memory-optimized, high-frequency [Amazon EC2 R7iz](/ec2/instance-types/r7iz/) instances are available in preview. R7iz instances are the first EC2 instances powered by 4th generation Intel Xeon Scalable processors (code named Sapphire Rapids) with an all core turbo frequency up to 3.9 GHz. These instances have the highest performance per vCPU among x86-based EC2 instances, and they deliver up to 20% higher performance than z1d instances. The instances are built on the [AWS Nitro System](/ec2/nitro/), a combination of dedicated hardware and lightweight hypervisor that delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security. R7iz instances are ideal for front-end Electronic Design Automation (EDA), relational database 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 various sizes, including two bare metal sizes, with up to 128 vCPUs and up to 1,024GiB of memory. R7iz instances are the first x86-based EC2 instances to 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.
