en.Wedoany.com Reported - Amazon Web Services (AWS) has launched the Graviton5 processor with support for PCIe 6.0, becoming the first vendor to offer this interface standard to users in commercial cloud infrastructure. The processor is now available to users through Amazon EC2 M9g and M9gd instances, allowing hourly rental of PCIe 6.0 hardware.
The Graviton5, developed by AWS's Annapurna Labs team, adopts a chiplet design based on TSMC's 3nm manufacturing process. The processor integrates four compute dies, each containing 48 Arm v3 cores, for a total of 192 cores. Each core has 1MB of dedicated cache, and the platform features 12 DDR5 memory channels running at speeds up to DDR5-8800, delivering over 800GB/s of aggregate memory bandwidth under demanding workloads. The processor includes 96 PCIe 6.0 lanes, making it the first cloud CPU with PCIe 6.0 support that users can actively access. Communication between chiplets relies on a coherent interconnect, capable of transferring data at 420GB/s while maintaining unified operation.
According to AWS data, the Graviton5 offers up to a 25% performance improvement over the previous generation. In application workloads, performance can be up to 35% faster, and database operations see a 30% improvement under appropriate conditions. Network bandwidth has increased by 15%, and storage bandwidth by approximately 20%. For large-scale deployments, network throughput can double compared to the previous generation. The M9gd instances also include local SSD storage with capacities up to 11.4TB, offering 30% higher IOPS than the previous generation.
Despite its technical advantages, the practical benefits of PCIe 6.0 are currently limited by the peripheral hardware ecosystem. Few storage devices can currently utilize this interface standard. Micron's 9650 NVMe SSD is one of the first PCIe 6.0 drives to reach commercial availability, with sequential read speeds of approximately 28GB/s, primarily targeting AI inference environments rather than traditional cloud workloads. Teamgroup's PCIe 6.0 SSD also achieves 28GB/s, but mainstream adoption remains distant.
For most AWS customers, factors such as processor architecture, memory bandwidth, cache capacity, and software optimization may have a more significant practical impact. The launch of the Graviton5 marks an evolution in cloud infrastructure interface standards, but the widespread value of this technology depends on the maturity of the hardware and software ecosystem supporting PCIe 6.0.
