Amazon Web Services (AMZN) has unleashed the Graviton5, which it said is its most powerful and efficient central processing unit, as the cloud and e-commerce giant continues to expand its chip offerings.
Although AWS continues to use chips from Nvidia (NVDA), Intel (INTC) and AMD (AMD) in its data centers, its leadership has always stressed the importance of offering its clientele an array of choices. This marks the third year in a row that more than half of the new CPU capacity added to AWS was powered by Graviton.
“Traditional approaches often force trade-offs, leaving you to choose between speed and efficiency,” AWS said. “To address this need, today we are introducing Graviton5 processors—AWS’s most advanced custom chip to date for a broad set of cloud workloads. Graviton5 delivers up to 25% better compute performance than the previous generation while maintaining leading energy efficiency, enabling you to run applications faster, reduce costs, and meet sustainability goals.”
Some of the large-scale AWS customers utilizing Graviton chips include Adobe (ADBE), Airbnb (ABNB), SAP (SAP), Snowflake (SNOW), Synopsys (SNPS), Atlassian (TEAM), Siemens (OTCPK:SIEGY), Pinterest (PINS), and Epic Games.
“Demanding workloads like real-time gaming, high-performance databases, big data analytics, application servers, and Electronic Design Automation can now scale up with faster data exchange between processing cores,” AWS said.
Each Graviton5 core has access to 2.6x more L3 cache than the Graviton4. It also has 15% to 20% more network and storage bandwidth. It is built with 3-nanometer technology, which was also used on AWS’ new Trainium3 chip, which was released earlier this week.
Graviton5-based M9g instances designed for general-purpose workloads are available in preview now. C9g instances for compute-intensive workloads and R9g instances for memory-intensive workloads are planned for 2026.
The announcements coincide with AWS’s re:Invent 2025 conference being held this week in Las Vegas. AWS recently reached an annual revenue run rate of $132B.
