Amazon EC2 C7a instances now available in the US West (N. California) Region

Amazon EC2 C7a instances, powered by 4th Gen AMD EPYC processors, deliver up to 50% higher performance than C6a instances with DDR5 memory and support for up to 128 EBS volumes per instance.

Amazon EC2 C7a instances are now available in the AWS US West (N. California) Region. Powered by 4th Gen AMD EPYC processors (code-named Genoa) with a maximum frequency of 3.7 GHz, C7a instances deliver up to 50% higher performance compared to C6a instances. They offer new processor capabilities such as AVX-512, VNNI, and bfloat16, and feature Double Data Rate 5 (DDR5) memory for high-speed data access with 2.25x more memory bandwidth than C6a instances, making them ideal for latency-sensitive workloads. C7a instances come in 12 sizes from medium to 48xlarge, including a bare-metal size. With the launch of C7a instances, customers can attach up to 128 EBS volumes to an EC2 instance, compared to C6a instances which allow up to 28 EBS volume attachments. Built on the AWS Nitro System, these instances are ideal for high-performance, compute-intensive workloads such as batch processing, distributed analytics, high-performance computing (HPC), ad serving, highly scalable multiplayer gaming, and video encoding. C7a instances are available through On-Demand, Spot Instances, and Savings Plans.
