Amazon introduced the EC2 C7a instances powered by 4th Gen AMD EPYC Genoa processors, boosting maximum frequency to 3.7 GHz and providing up to 50% higher performance compared to the preceding C6a instances. Equipped with advanced processor features such as AVX-512, VNNI, and bfloat16, along with DDR5 memory for 2.25 times greater bandwidth, these instances target latency-sensitive, compute-intensive applications.
The C7a family includes 12 sizes, from medium to 48xlarge, and introduces support for attaching up to 128 EBS volumes per instance, a significant increase over the C6a limit of 28. Built on AWS Nitro System, they serve workloads like batch processing, distributed analytics, HPC, gaming, and video encoding, available through multiple pricing models, including On-Demand and Spot Instances.
