AWS reveals pricing and benefits of R6i instances vs R5 instances

Amazon Web Services (AWS) announced the pricing and advantages of the Amazon EC2 R6i instances powered by Intel Xeon Scalable processors.
AWS event for CIOsToday’s news follows two earlier Amazon announcements of its EC2 instances powered by 3rd generation Intel Xeon Scalable processors, the Amazon EC2 M6i and C6i instances.

Advantages of new R6i instances vs R5 instances

# A larger instance size (r6i.32xlarge) with 128 vCPUs and 1,024 GiB of memory that makes it easier and more cost-efficient to consolidate workloads and scale up applications

# Up to 15 percent improvement in compute price/performance

# Up to 20 percent higher memory bandwidth

# Up to 40 Gbps for Amazon Elastic Block Store (EBS) and 50 Gbps for networking which is 2x more than R5 instances

# Always-on memory encryption

The R6i instances are powered by 3rd generation Intel Xeon Scalable processors (code named Ice Lake). Amazon measured up to 15 percent better compute price performance over R5 instances, with an all-core turbo frequency of 3.5 GHz and always-on memory encryption using Intel Total Memory Encryption (TME).

R6i instances are SAP-Certified and are ideal for workloads such as relational and noSQL databases, distributed web scale in-memory caches like Memcached and Redis, in-memory databases like SAP HANA, and real time big data analytics like Hadoop and Spark clusters.

Built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor, R6i instances deliver practically all of the compute and memory resources of the host hardware to the customers’ instance.

R6i instances provide two new sizes (32xlarge and metal) with 128 vCPUs and 1,024 GiB of memory, which is 33 percent more than the largest previous generation R5 instance. They  provide up to 20 percent higher memory bandwidth per vCPU compared to R5 instances, AWS said.

The EC2 R6i instances are generally available today in AWS Regions: U.S. East (Ohio), U.S. East (Northern Virginia), U.S. West (Oregon), Europe (Ireland).

Availability and Pricing
EC2 R6i instances are available in four AWS Regions: US East (N. Virginia), US West (Oregon), US East (Ohio), Europe (Ireland). Customers can pay for what they use. For more information, see the EC2 pricing page.

AWS is the #1 cloud service provider well ahead of Microsoft and Google Cloud in terms of revenue share.
