AWS Graviton5 is its most powerful and efficient CPU to date - and could mean big changes for your key cloud workloads (www.techradar.com)

Amazon Web Services (AWS) has announced the launch of its most powerful CPU to date, the Graviton5, at its re:Invent 2025 event. Built using cutting-edge 3nm technology, the Graviton5 significantly enhances efficiency and performance for demanding workloads in sectors like high-performance databases and big data analytics. The introduction of Graviton5-based EC2 M9g instances showcases this hardware's potential, featuring 192 cores with over five times the L3 cache of previous generations. This setup allows for substantial performance improvements, with each core benefiting from 2.6 times more L3 cache, driving better overall performance and consistency. The Graviton5 also boasts enhanced memory speeds and up to 15% higher network bandwidth, alongside 20% increased Amazon Elastic Block Store (EBS) bandwidth. These advancements promise faster data transfers and more efficient processing of larger datasets, which is crucial for memory-intensive applications. Early adopters like Adobe and Airbnb are already experiencing notable performance gains, indicating that Graviton5 could lead to significant changes in cloud computing practices and sustainability efforts within the AI/ML community.
