AWS announces the general availability of Amazon Elastic Compute Cloud (Amazon EC2) Hpc7g instances. Amazon EC2 Hpc7g instances are powered by AWS Graviton processors, which are custom Arm-based processors designed by AWS. Arm-based architectures are known for their higher core counts with better performance per watt and their energy efficiency owing to simple instructions (RISC) that generate less heat, offering better heat dissipation.
