New – Amazon EC2 R7a Situations Powered By 4th Gen AMD EPYC Processors for Reminiscence Optimized Workloads


Voiced by Polly

We launched the reminiscence optimized Amazon EC2 R6a cases in July 2022 powered by third Gen AMD EPYC (Milan) processors, working at frequencies as much as 3.6 GHz. Many purchasers who run workloads which are depending on x86 directions, resembling SAP, are on the lookout for methods to optimize their cloud utilization. They’re benefiting from the compute selection that EC2 presents.

Immediately, we’re asserting the final availability of recent reminiscence optimized Amazon EC2 R7a cases powered by 4th Gen AMD EPYC (Genoa) processors with a most frequency of three.7 GHz, which provide as much as 50 % increased efficiency in comparison with the earlier era cases. You should use this elevated efficiency to course of information sooner, consolidate workloads, and decrease the price of possession.

R7a cases additionally help AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These cases function Double Information Price 5 (DDR5) reminiscence, which permits high-speed entry to information in-memory, and ship 2.25 occasions extra reminiscence bandwidth in comparison with R6a cases for decrease latency. Furthermore, these cases help always-on reminiscence encryption utilizing AMD safe reminiscence encryption (SME).

These cases are SAP-certified and best for prime efficiency, memory-intensive workloads, resembling SQL and NoSQL databases, distributed net scale in-memory caches, in-memory databases, real-time massive information analytics, and Digital Design Automation (EDA) purposes.

R7a cases function sizes of as much as 192 vCPUs with 1536 GiB RAM. Listed below are the detailed specs:

Identify vCPUs Reminiscence (GiB) Community Bandwidth (Gbps) EBS Bandwidth (Gbps)
r7a.medium 1 8 As much as 12.5 As much as 10
r7a.giant 2 16 As much as 12.5 As much as 10
r7a.xlarge 4 32 As much as 12.5 As much as 10
r7a.2xlarge 8 64 As much as 12.5 As much as 10
r7a.4xlarge 16 128 As much as 12.5 As much as 10
r7a.8xlarge 32 256 12.5 10
r7a.12xlarge 48 384 18.75 15
r7a.16xlarge 64 512 25 20
r7a.24xlarge 96 768 37.5 30
r7a.32xlarge 128 1024 50 40
r7a.48xlarge 192 1536 50 40

R7a cases have as much as 50 Gbps enhanced networking and 40 Gbps EBS bandwidth, which has similarities to R6a cases. You might have a brand new medium occasion dimension, which you need to use to right-size your workloads extra precisely, providing 1 vCPUs, 8 GiB. Moreover, with R7a cases you possibly can connect as much as 128 EBS volumes to an occasion in comparison with as much as 28 EBS quantity attachments with R6a cases. R7a cases help AES-256 in comparison with AES-128 in R6a cases for enhanced safety.

R7a cases are constructed on the AWS Nitro System and help Elastic Cloth Adapter (EFA) for workloads that profit from decrease community latency and extremely scalable inter-node communication, resembling high-performance computing and video processing.

Now Accessible
Amazon EC2 R7a cases at the moment are accessible in AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As regular with Amazon EC2, you solely pay for what you employ. For extra data, see the Amazon EC2 pricing web page.

To be taught extra, go to the EC2 R7a cases web page, and AWS/AMD associate web page. You possibly can ship suggestions to, AWS re:Put up for EC2, or by your regular AWS Assist contacts.
