The C7g instances also deliver 20 percent higher networking bandwidth capabilities compared to AWS Graviton2-based instances and support Elastic Fabric Adapter (EFA), which allows applications to communicate directly with network interface cards, enhancing the performance of HPC and other applications. The C7g instances use the latest DDR5 memory, which provides 50 percent higher memory bandwidth compared to AWS Graviton2-based instances, which improves the performance of memory-intensive applications like scientific computing. 30 blog post announcing the new Graviton3 instances, Jeff Barr, chief evangelist for AWS, wrote that that the new offerings will better serve customers who need to run compute-intensive workloads including HPC, batch processing, electronic design automation (EDA), media encoding, scientific modeling, ad serving, distributed analytics, and CPU-based machine learning inferencing.Īccording to AWS, the new Graviton3-powered instances are up to 60 percent more energy efficient than the previous Graviton2-powered EC2 instances. The AWS Graviton2 processors debuted in late 2019, a year after the initial Graviton chips were unveiled. AWS customers today have a choice of about 12 different Graviton2-powered instances. All Graviton processors include dedicated cores and caches for each vCPU.
The AWS Graviton chips are Arm-based 7nm processors designed by AWS and custom-built for cloud workloads by Israeli-based engineering firm Annapurna Labs, which AWS acquired about six years ago. AWS CEO Adam Selipsky introduces Graviton3-backed instances live at re:Invent on Nov. The new Graviton3 instances are also up to 2x faster when running cryptographic workloads compared to AWS Graviton2 instances, the company said.įor machine learning workloads, the new Graviton3-powered instances are expected to deliver up to 3x better performance compared to Graviton2-powered instances, including support for bfloat16, said AWS. Three years after unveiling the first generation of its AWS Graviton chip-powered instances in 2018, Amazon Web Services announced that the third generation of the processors – the AWS Graviton3 – will power all-new Amazon Elastic Compute 2 (EC2) C7g instances that are now available in preview.ĭebuting at the AWS re:Invent 2021 conference in Las Vegas, the new Graviton3-powered instances will deliver up to 25 percent faster compute performance and up to 2x higher floating-point performance compared to the current generation of AWS EC2 C6g Graviton2-powered instances, according to AWS.
