New EC2 R7iz Instances

AWS Activates 4th Gen Intel Xeon Scalable Processors for New EC2 R7iz Instances.

New instances deliver up to 20% higher performance with Sapphire Rapids.

November 28, 2022 – Amazon Web Services (AWS) announced the private preview of Amazon EC2 R7iz instances powered by 4th Gen Intel® Xeon® Scalable processors, code-named Sapphire Rapids.

R7iz instances deliver an all-core turbo frequency up to 3.9 gigahertz and AWS claim up to 20% higher performance over comparable high-frequency EC2 instances. Leveraging 4th Gen Intel Xeon Scalable processors and AWS Nitro System, R7iz instances offer a combination of dedicated hardware and a lightweight hypervisor – delivering better overall cost, performance and security.

Customers can now take advantage of accelerated performance for compute-intensive and memory-intensive workloads, including front-end electronic design automation (EDA), relational database workloads with high per-core licensing fees, and workloads for financial, actuarial and data analytics simulation.

To meet customer demands for increased memory and scalability, R7iz instances are available in various sizes with up to 128 vCPUs and up to 1,024 gigabytes of memory, resulting in up to 2.6 times more vCPU and memory than comparable high-frequency instances. The first x86-based EC2 instances to use DDR5 memory, R7iz delivers up to 2.4 times higher memory bandwidth than comparable high frequency instances.

“Data center customers are looking to keep up with demand, increase business value of their data and improve their overall costs,” said Lisa Spelman, corporate vice president and general manager of Intel Xeon Products. “AWS is delivering new instances that leverage the accelerated performance and security of 4th Gen Intel Xeon to support the most demanding workloads.”

As per AWS:

Starting today, memory-optimized, high-frequency Amazon EC2 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, 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.
