Amazon Unveils Graviton 4 EC2 Instances Featuring Enhanced Networking Capabilities
Seattle, WA – July 2, 2025 – Amazon Web Services (AWS) has announced the latest iteration of its custom-designed Arm-based processors for its Elastic Compute Cloud (EC2) instances, the Graviton 4. This new generation brings significant advancements, most notably the integration of dual 300Gbps network interface controllers (NICs) across its EC2 offerings. This substantial upgrade in networking throughput is poised to deliver enhanced performance and efficiency for a wide array of cloud workloads.
The Graviton processors, developed by AWS, are engineered to offer a compelling combination of performance, cost-effectiveness, and power efficiency, particularly for cloud-native applications. By leveraging the Arm architecture, Graviton instances have consistently provided a strong alternative to traditional x86-based processors. The introduction of Graviton 4, with its bolstered networking capabilities, signifies AWS’s commitment to further optimizing its infrastructure for the evolving demands of modern cloud computing.
The inclusion of dual 300Gbps NICs represents a considerable leap forward in network bandwidth for Graviton-powered EC2 instances. This enhanced throughput is particularly beneficial for applications that are heavily reliant on network performance. Examples include high-performance computing (HPC) clusters, big data analytics, machine learning training and inference, real-time data processing, and large-scale content delivery networks. With double the network capacity compared to previous generations, these instances can now handle significantly larger volumes of data transfer with greater speed and reduced latency.
This networking prowess is expected to translate into tangible benefits for AWS customers. By enabling faster data ingestion and egress, Graviton 4 instances can accelerate complex data analysis tasks, reduce the time required for model training in machine learning, and improve the responsiveness of latency-sensitive applications. Furthermore, the increased bandwidth can contribute to greater efficiency by allowing more operations to be performed concurrently, potentially leading to cost savings through optimized resource utilization.
The Graviton 4 processors themselves are also expected to feature architectural improvements over their predecessors, although specific details on core count, clock speeds, and cache configurations have not yet been fully elaborated. However, the strategic focus on network performance underscores AWS’s understanding of the critical role networking plays in achieving peak application performance within the cloud.
This announcement positions AWS to further solidify its leadership in providing high-performance and cost-efficient computing solutions. The Graviton 4 EC2 instances, with their advanced networking, are likely to be a compelling option for businesses seeking to maximize the performance and value of their cloud deployments, particularly those undertaking data-intensive and network-bound operations. Customers can anticipate a more robust and responsive cloud experience as these new instances become widely available.
