- AWS Graviton5 launches at re:Invent 2025
- New CPU offers huge leaps in efficiency and performance
- New Graviton5-based EC2 M9g instances show potential
Amazon Web Services (AWS) has unveiled its next big hardware advancement with the launch of the AWS Graviton5 CPU.
Announced at AWS re:Invent 2025 and intended to address demanding workloads in industries such as high-performance databases, big data analytics, and application servers, Graviton5 offers customers a much more efficient way to process their data.
Employing the latest 3nm technology, Graviton5 also enables improved cooling and energy efficiency, helping customers meet sustainability goals without compromising capacity.
AWS Graviton5 is here
The new hardware is showcased in AWS’s new Graviton5-based EC2 M9g instances, which it says offer the highest CPU core density available on Amazon EC2.
“Graviton5 offers 192 cores in one package and offers more than five times the L3 cache of previous generations,” Dave Brown, vice president of AWS Compute Services and Machine Learning, stated today at AWS re:Invent 2025, “that means each core now gets up to 2.6 times more L3 cache, and that leads to better overall performance and consistency.”
AWS said memory performance has also improved in Graviton5, which now provides faster memory speeds, allowing it to process larger data sets and run memory-intensive applications more efficiently.
Graviton5 also delivers up to 15% more network bandwidth and 20% more Amazon Elastic Block Store (EBS) bandwidth on average across all instance sizes, and up to 2x more network bandwidth for larger instances. This should lead to faster data transfers, faster backups, and better performance for distributed applications; Customers like Adobe and Airbnb are already seeing significant improvements across the board.
