New – Amazon EC2 C7a Instances Powered By 4th Gen AMD EPYC Processors for Compute Optimized Workloads


Voiced by Polly

We launched the compute optimized Amazon EC2 C6a situations in February 2022 powered by third Gen AMD EPYC (Milan) processors, working at frequencies as much as 3.6 GHz.

Today, we’re saying the overall availability of latest, compute optimized Amazon EC2 C7a situations, powered by the 4th Gen AMD EPYC (Genoa) processors with a most frequency of three.7 GHz, which provide as much as 50 p.c larger efficiency in comparison with C6a situations. You can use this elevated efficiency to course of knowledge quicker, consolidate workloads, and decrease the price of possession.

C7a situations offer as much as 50 p.c larger efficiency in comparison with C6a situations. These situations are perfect for working compute-intensive workloads resembling high-performance internet servers, batch processing, advert serving, machine studying, multiplayer gaming, video encoding, excessive efficiency computing (HPC) resembling scientific modeling, and machine studying.

C7a situations help AVX-512, Vector Neural Network Instructions (VNNI), and mind floating level (bfloat16). These situations characteristic Double Data Rate 5 (DDR5) reminiscence, which allows high-speed entry to knowledge in-memory, and ship 2.25 instances extra reminiscence bandwidth in comparison with the earlier technology situations for decrease latency.

C7a situations characteristic sizes of as much as 192 vCPUs with 384 GiB RAM, which you’ve gotten a brand new medium occasion dimension, which allows you to right-size your workloads extra precisely, providing 1 vCPU, 2 GiB. Here are the detailed specs:

NamevCPUsMemory (GiB)Network Bandwidth (Gbps)EBS Bandwidth (Gbps)
c7a.medium12Up to 12.5Up to 10
c7a.giant24Up to 12.5Up to 10
c7a.xlarge48Up to 12.5Up to 10
c7a.2xlarge816Up to 12.5Up to 10
c7a.4xlarge1632Up to 12.5Up to 10

C7a situations have as much as 50 Gbps enhanced networking and 40 Gbps EBS bandwidth, and you’ll connect as much as 128 EBS volumes to an occasion, in comparison with as much as 28 EBS quantity attachments with the earlier technology situations.

C7a situations help always-on reminiscence encryption with AMD safe reminiscence encryption (SME) and new AVX-512 directions for accelerating encryption and decryption algorithms, convolutional neural community (CNN) based mostly algorithms, monetary analytics, and video encoding workloads. C7a situations additionally help AES-256 in comparison with AES-128 in C6a situations for enhanced safety.

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

Now Available
Amazon EC2 C7a situations at the moment are obtainable within the following AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Ireland). As regular with Amazon EC2, you solely pay for what you utilize. For extra data, see the Amazon EC2 pricing web page.

To be taught extra, go to the EC2 C7a situations web page and AWS/AMD associate web page. You can ship suggestions to, AWS re:Post for EC2, or by way of your regular AWS Support contacts.
