AMD and Amazon just introduced Elastic Compute Cloud EC2 C5a instances that run on 2nd Gen AMD EPYC processors, promising better performance at lower costs!
Amazon EC2 C5a Now Runs On 2nd Gen AMD EPYC!
The new Amazon Elastic Compute Cloud EC2 C5a instances are powered by a 2nd Gen AMD EPYC processor running at up to 3.3 GHz.
These C5a instances are designed to deliver the best possible price-performance value for compute-intensive workloads like batch processing, distributed analytics, data transformations, log analytics and web applications.
In the beginning, Amazon will offer these eight EC2 C5a instances, which will cost 10% less than comparable instances.
| EC2 C5a Instance |
vCPUs | RAM | EBS-Optimised Bandwidth |
Network Bandwidth |
| c5a.large | 2 | 4 GiB | Up to 3.710 Gbps | Up to 10 Gbps |
| c5a.xlarge | 4 | 8 GiB | Up to 3.710 Gbps | Up to 10 Gbps |
| c5a.2xlarge | 8 | 16 GiB | Up to 3.710 Gbps | Up to 10 Gbps |
| c5a.4xlarge | 16 | 32 GiB | Up to 3.710 Gbps | Up to 10 Gbps |
| c5a.8xlarge | 32 | 64 GiB | 3.710 Gbps | 10 Gbps |
| c5a.12xlarge | 48 | 96 GiB | 4.750 Gbps | 12 Gbps |
| c5a.16xlarge | 64 | 128 GiB | 6.3 Gbps | 20 Gbps |
| c5a.24xlarge | 96 | 192 GiB | 9.5 Gbps | 20 Gbps |
These instances are fully 64-bit x86 compatible, and managed by the same Nitro platform used across Amazon EC2, with similar sizes as C5 instances, and the AMIs work on either.
They will eventually add disk variants like C5ad (with fast, local NVMe instance storage) and bare metal variants like C5an.metal and C5adn.metal.
