Graviton2, aws announces 64-core arm chip for servers
Table of contents:
In late November 2018, Amazon Web Services made an announcement that signaled a changing dynamic in the semiconductor industry. AWS's Graviton processor, with 16 of ARM's Cortex-72 cores, was officially announced at this time. The chip powered AWS's cloud server platform and its launch introduced ARM's chip designs for the cloud. Now, Amazon announced the Graviton2 processor, with greater computing power.
Graviton2 offers great performance improvements over the first generation of AWS Graviton CPUs
A year after the announcement of the first generation Graviton, AWS has returned with a completely different chip called the Graviton2. This chip features 64 Neoverse N1 ARM cores, is manufactured at the 7nm process node, packs 30 billion transistors, and supports eight channels of DDR4-3200 memory.
Amazon introduces its Graviton2 processor for M6g, C6g, and R6G EC2 workloads with up to 40% performance gain and 20% energy efficiency compared to Amazon EC2 M5 instances.
The Graviton2 is a great improvement over its predecessor. ARM's Neoverse N1 cores are specifically designed for the server market, and were announced earlier this year. The N1 CPU shares its design with ARM's Cortex A76 CPUs, but as it is designed for the infrastructure market, key optimizations ensure that successive iterations of Neoverse and the N1 CPU will become increasingly proficient.

Compared to the Graviton, the Graviton2 features serious performance improvements in every respect. The chip improves performance on SPECint2017, SPECjvn2008, and Memcached by 40%, performance on SPECfp2017, NGINX, and media encoding for uncompressed 1080p to H.264 by 20%, deep learning performance by 25%, and exploratory data performance by 50%.
The launch of Graviton2 confirms that Amazon's plans to give diversity to its cloud platform. AWS now offers Intel, AMD, and Graviton processors, and the Graviton2 will also power AWS next-generation EC2 instances to match what their AMD and Intel instances already offer.
