chip WX5025

Overview

The Netswift WX5025 chip is a 25G Ethernet controller chip with independent intellectual property rights released by Netxun Technology in 2024. It has ultra-low power consumption performance under the same working state in the industry, improves computing performance and reduces TCO. It supports up to PCIe Gen4 x8 (compatible with PCIe Gen4/3/2/1, x4/x2/x1), supports 10/25GbE Ethernet ports, and supports hardware isolation and virtualization. WX5025 provides high-performance and flexible network processing capabilities for cloud computing, network security, storage, big data analysis, database and other applications.
