AWS previewed Graviton4 at its re:Invent 2023 conference, and since then, more than 100 customers have tested their workloads on AWS Graviton4-based R8g instances, according to Kayabali. “SmugMug achieved 20-40% performance improvements using AWS Graviton4-based instances compared to AWS Graviton3-based instances for their image and data compression operations. Epic Games found AWS Graviton4 instances to be the fastest EC2 instances they have ever tested and Honeycomb.io achieved more than double the throughput per vCPU compared to the non-Graviton based instances that they used four years ago,” Kayabali wrote.
Amazon also claims R8g instances provide the best energy efficiency for memory-intensive workloads in EC2, but it did not give numbers or specifics.
R8g instances will be rolled out across different Amazon zones over time. They’re currently available in the following AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Frankfurt).
