- AWS Graviton5 will be launched at re:Invent 2025
- New CPU offers huge advances in efficiency and performance
- New Graviton5-based EC2 M9g instances show the potential
Amazon Web Services (AWS) has unveiled its next major hardware advancement with the launch of the AWS Graviton5 CPU.
Announced at AWS re:Invent 2025 and aimed at tackling demanding workloads from industries such as high-performance databases, big data analytics, application servers, Graviton5 gives customers a much more efficient way to process their data.
By using the latest 3nm technology, the Graviton5 also allows for improved cooling and energy efficiency, helping customers achieve sustainability goals without compromising on capacity.
AWS Graviton5 is here
The new hardware is being showcased in AWS’ new Graviton5-based EC2 M9g instances, which it says offer the highest CPU core density available in Amazon EC2.
“Graviton5 delivers 192 cores in one package and delivers more than five times the L3 cache over previous generations,” declared Dave Brown, VP, Compute and Machine Learning Services, AWS at AWS re:Invent 2025 today, “meaning each core now gets up to 2.6 times more L3 cache, leading to better performance and coherence overall.”
AWS said that memory performance has also improved in Graviton5, which now provides faster memory speeds, allowing you to process larger data sets and run memory-intensive applications more efficiently.
Graviton5 also offers up to 15% higher network bandwidth and 20% higher Amazon Elastic Block Store (EBS) bandwidth on average across instance sizes and up to double the network bandwidth for the largest instances. This should lead to faster data transfers, faster backups and improved performance for distributed applications – with customers like Adobe and Airbnb already seeing big improvements across the board.
