Amazon EC2 C6a Instances

Compute optimized instances powered by third generation AMD EPYC processors

Why Amazon EC2 C6a Instances?

Amazon EC2 C6a instances are powered by 3rd generation AMD EPYC processors, deliver up to 15% better price performance compared to C5a instances, and offer 10% lower cost than comparable x86-based EC2 instances. C6a instances feature a 2:1 ratio of memory to vCPU, just like C5a instances and support increased sizes up to 192 vCPUs per instance, which is double that of C5a instances. These instances feature more than twice the network bandwidth of C5a instances, and are designed for compute-intensive workloads such as batch processing, distributed analytics, high performance computing (HPC), ad serving, highly-scalable multiplayer gaming, and video encoding.
