We launched the compute optimized Amazon EC2 C6a situations in February 2022 powered by third Gen AMD EPYC (Milan) processors, operating at frequencies as much as three.6 GHz.

Immediately, we’re asserting 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 supply as much as 50 % increased efficiency in comparison with C6a situations. You should use this elevated efficiency to course of information quicker, consolidate workloads, and decrease the price of possession.

C7a situations offer as much as 50 % increased efficiency in comparison with C6a situations. These situations are perfect for operating compute-intensive workloads equivalent to high-performance net servers, batch processing, advert serving, machine studying, multiplayer gaming, video encoding, excessive efficiency computing (HPC) equivalent to scientific modeling, and machine studying.

C7a situations assist AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These situations function Double Knowledge Fee 5 (DDR5) reminiscence, which allows high-speed entry to information in-memory, and ship 2.25 occasions extra reminiscence bandwidth in comparison with the earlier era situations for decrease latency.

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

Identify vCPUs Reminiscence (GiB) Community Bandwidth (Gbps) EBS Bandwidth (Gbps)
c7a.medium 1 2 As much as 12.5 As much as 10
c7a.giant 2 four As much as 12.5 As much as 10
c7a.xlarge four eight As much as 12.5 As much as 10
c7a.2xlarge eight 16 As much as 12.5 As much as 10
c7a.4xlarge 16 32 As much as 12.5 As much as 10
c7a.8xlarge 32 64 12.5 10
c7a.12xlarge 48 96 18.75 15
c7a.16xlarge 64 128 25 20
c7a.24xlarge 96 192 37.5 30
c7a.32xlarge 128 256 50 40
c7a.48xlarge 192 384 50 40
c7a.metal-48xl 192 384 50 40

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

C7a situations assist 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 assist AES-256 in comparison with AES-128 in C6a situations for enhanced safety.

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

Now Accessible
Amazon EC2 C7a situations are actually accessible within the following AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As ordinary 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 accomplice web page. You’ll be able to ship suggestions to ec2-amd-customer-feedback@amazon.com, AWS re:Submit for EC2, or by your ordinary AWS Help contacts.
