We launched the compute optimized Amazon EC2 C6a cases in February 2022 powered by third Gen AMD EPYC (Milan) processors, operating at frequencies as much as 3.6 GHz.
At this time, we’re saying the overall availability of recent, compute optimized Amazon EC2 C7a cases, powered by the 4th Gen AMD EPYC (Genoa) processors with a most frequency of three.7 GHz, which supply as much as 50 p.c increased efficiency in comparison with C6a cases. You should use this elevated efficiency to course of information quicker, consolidate workloads, and decrease the price of possession.
C7a cases o?er as much as 50 p.c increased efficiency in comparison with C6a cases. These cases are perfect for operating compute-intensive workloads reminiscent of high-performance internet servers, batch processing, advert serving, machine studying, multiplayer gaming, video encoding, excessive efficiency computing (HPC) reminiscent of scientific modeling, and machine studying.
C7a cases assist AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These cases function Double Knowledge Fee 5 (DDR5) reminiscence, which permits high-speed entry to information in-memory, and ship 2.25 instances extra reminiscence bandwidth in comparison with the earlier era cases for decrease latency.
C7a cases function sizes of as much as 192 vCPUs with 384 GiB RAM, which you have got a brand new medium occasion dimension, which lets you right-size your workloads extra precisely, providing 1 vCPU, 2 GiB. Listed below 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 | 4 | As much as 12.5 | As much as 10 |
| c7a.xlarge | 4 | 8 | As much as 12.5 | As much as 10 |
| c7a.2xlarge | 8 | 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 cases 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 era cases.
C7a cases 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 cases additionally assist AES-256 in comparison with AES-128 in C6a cases for enhanced safety.
These cases are constructed on the AWS Nitro System and assist Elastic Cloth Adapter (EFA) for workloads that profit from decrease community latency and extremely scalable inter-node communication, reminiscent of high-performance computing and video processing.
Now Accessible
Amazon EC2 C7a cases at the moment are obtainable within the following AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As typical with Amazon EC2, you solely pay for what you utilize. For extra info, see the Amazon EC2 pricing web page.
To study extra, go to the EC2 C7a cases web page and AWS/AMD accomplice web page. You may ship suggestions to ec2-amd-customer-feedback@amazon.com, AWS re:Submit for EC2, or by way of your typical AWS Help contacts.
