AWS to Unveil Graviton4 Update with Industry-Leading 600 Gbps Cloud Network Speed by June End

Amazon Web Services (AWS) is preparing to roll out an upgrade to its Graviton4 chip, featuring 600 gigabits per second of network bandwidth—the highest offered in the public cloud, CNBC reported. Graviton4-powered instances currently offer network speeds of up to 50 Gbps.

AWS plans to announce the Graviton4 update schedule by the end of June.

It is also reported that Trainium3 is set to launch later this year, which will deliver twice the performance of Trainium2. The chip will also reduce energy consumption by an additional 50%.

Graviton4 is the fourth generation in AWS’s custom Graviton CPU lineup, built on Arm Holdings’ Neoverse N2 architecture and featuring 96 cores. It includes a significantly larger L2 cache of 192 megabytes—up from just 8 megabytes in the original Graviton chip—and packs 73 billion transistors, according to AWS.

The chip also introduces enhanced cybersecurity features. It incorporates Arm’s Branch Target Identification (BTI) technology, which helps prevent attacks that exploit the CPU’s branch prediction system—a feature that anticipates calculations in advance to improve speed.

Additionally, all hardware interfaces used by Graviton4 to transmit data within AWS infrastructure are encrypted for added security.

Interestingly, Anthropic’s Claude Opus 4 model runs on these chips. At re:Invent 2024, AWS unveiled Project Rainier, an AI supercomputer built for Anthropic, powered by over 500,000 Trainium2 chips.
