AWS, a subsidiary of Amazon, has release their latest Graviton chip, Graviton5. The Graviton5 chips will be used to create M9g, C9g, and R9g instances once they’re released in 2026. M9g instances are designed for general purpose workloads, and are available for preview as of December 4, 2025. The C9g and R9g instances will be used for compute-intensive and memory-intensive workloads respectively.
Graviton chips are used to power numerous massive businesses such as Airbnb, Pinterest, Formula 1, Epic Games, and many more. Each of these companies report improved performance across numerous metrics upon utilizing the Graviton5 based instances.
The Graviton5 chips boast 192 cores in a single package, which reduces the distance data has to travel between cores. This new design decreases the latency of inter-core communication by 33%, while simultaneously increasing the bandwidth. This improvement of data transfer speeds allows for improved performance while under incredibly demanding workloads such as:
- real-time gaming
- high-performance databases
- big data analytics
- application servers
- and Electronic Design Automation (EDA)
The Graviton5 also reports a 5 times increase in the L3 cache size. For those who don’t know, L3 cache is data that the CPU frequently needs to access. Furthermore, each core has access to 2.6 times more L3 cache than its predecessor, the Graviton4 cores. This leap in L3 cache enables faster data transfers and increases the response times of applications.
Graviton5 also proudly boasts an average 20% increase in Amazon EBS (Elastic Block Store) bandwidth across several instance sizes, however there can be up to a 2 times increase of the network bandwidth for the largest instances. Aside from Amazon EBS, the Graviton5 also comes with a 15% overall increase in the network bandwidth; allowing for faster data transfers and performance.
AWS also reports their new Graviton5 chips as being significantly more energy efficient. This leap in efficiency is due to the utilization of the latest 3nm technology. They also utilize bare-die cooling, which is when you put a liquid coolant directly on the die of a CPU.
As the demand for better cloud computing increases, it is great to see that AWS is managing to exceed demand with powerful leaps in computing. As more websites use their cloud computing services, will AWS be able to stay ahead of demand? Only time will tell.
