Today, I’m happy to share that we’re expanding these seventh-generation x86-based offerings to include memory-optimized Amazon EC2 R7i instances. These instances are powered by custom 4th Generation Intel Xeon Scalable Processors (Sapphire Rapids) exclusive to AWS and will offer the highest compute performance among the comparable fourth-generation Intel processors in the cloud. The R7i instances are available in eleven sizes including two bare metal sizes (coming soon), and offer 15 percent improvement in price-performance compared to Amazon EC2 R6i instances.
Amazon EC2 R7i instances are SAP Certified and are an ideal fit for memory-intensive workloads such as high-performance databases (SQL and NoSQL databases), distributed web scale in-memory caches (Memcached and Redis), in-memory databases (SAP HANA), real-time big data analytics (Apache Hadoop and Spark clusters) and other enterprise applications. Amazon EC2 R7i offers larger instance sizes (48xlarge) with up to 192 vCPUs and 1,536 GiB of memory, including both virtual and bare metal instances, enabling you to consolidate your workloads and scale-up applications.
You can attach up to 128 EBS volumes to each R7i instance; by way of comparison, the R6i instances allow you to attach up to 28 volumes.
Here are the specs for the R7i instances:
|r7i.large||2||16 GiB||Up to 12.5 Gbps||Up to 10 Gbps|
|r7i.xlarge||4||32 GiB||Up to 12.5 Gbps||Up to 10 Gbps|
|r7i.2xlarge||8||64 GiB||Up to 12.5 Gbps||Up to 10 Gbps|
|r7i.4xlarge||16||128 GiB||Up to 12.5 Gbps||Up to 10 Gbps|
|r7i.8xlarge||32||256 GiB||12.5 Gbps||10 Gbps|
|r7i.12xlarge||48||384 GiB||18.75 Gbps||15 Gbps|
|r7i.16xlarge||64||512 GiB||25 Gbps||20 Gbps|
|r7i.24xlarge||96||768 GiB||37.5 Gbps||30 Gbps|
|r7i.48xlarge||192||1,536 GiB||50 Gbps||40 Gbps|
We’re also getting ready to launch two sizes of bare metal R7i instances soon:
|r7i.metal-24xl||96||768 GiB||37.5 Gbps||30 Gbps|
|r7i.metal-48xl||192||1,536 GiB||50.0 Gbps||40 Gbps|
The Sapphire Rapids processors include four built-in accelerators, each providing hardware acceleration for a specific workload:
Advanced Matrix Extensions are available on all sizes of R7i instances. The Intel QAT, Intel IAA, and Intel DSA accelerators will be available on the r7i.metal-24xl and r7i.metal-48xl instances.
The new instances are available in the US East (Ohio, N. Virginia), US West (Oregon), Europe (Spain), Europe (Stockholm), and Europe (Ireland) AWS Regions.
R7i instances are available in On-Demand, Reserved, Savings Plan, and Spot Instance form. R7i instances are also available in Dedicated Host and Dedicated Instance form.
