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.
At present, we’re saying the final 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 p.c greater efficiency in comparison with C6a situations. You should utilize this elevated efficiency to course of information quicker, consolidate workloads, and decrease the price of possession.
C7a situations offer as much as 50 p.c greater efficiency in comparison with C6a situations. These situations are perfect for working compute-intensive workloads reminiscent of high-performance net servers, batch processing, advert serving, machine studying, multiplayer gaming, video encoding, excessive efficiency computing (HPC) reminiscent of scientific modeling, and machine studying.
C7a situations help AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These situations characteristic Double Information Charge 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 technology situations for decrease latency.
C7a situations characteristic sizes of as much as 192 vCPUs with 384 GiB RAM, which you might have a brand new medium occasion measurement, which lets you right-size your workloads extra precisely, providing 1 vCPU, 2 GiB. Listed here are the detailed specs:
| Title | 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 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 Material 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 Obtainable
Amazon EC2 C7a situations at the moment are out there within the following AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As traditional with Amazon EC2, you solely pay for what you employ. For extra info, see the Amazon EC2 pricing web page.
To study extra, go to the EC2 C7a situations web page and AWS/AMD companion web page. You may ship suggestions to ec2-amd-customer-feedback@amazon.com, AWS re:Put up for EC2, or by means of your traditional AWS Help contacts.
