   Zhongxingwei launches China's first PCIe 6.0 switch and 800G AI NIC

   Chinese interconnect chip maker Zhongxingwei held its first brand and full-stack product launch in Wuxi, showing 12 mass-produced chips and releasing three new products: what it calls China's first PCIe 6.0 Switch (C82-4G), its first 800G multi-protocol AI NIC, and a multi-mode RAID chip. The C82-4G supports up to 144 PCIe 6.0 lanes at 64 GT/s per lane, double PCIe 5.0, plus Fabric networking and CXL memory pooling; the 800G AI NIC integrates a 48-lane PCIe Gen6 switch, targets Hygon CPUs and next-generation Compute Tray supernode architectures, and supports RoCE v2 and VeRoCE offload with hardware packet spraying, out-of-order reassembly and programmable congestion control. The company said it shipped more than 400,000 chips in 2025 with over 1 billion yuan in sales and more than 800,000 cumulative units, and claims its multi-mode RAID chip roughly doubles overseas advanced products and delivers up to a 47% write-bandwidth edge over Broadcom in a 16-drive RAID5 256KiB sequential write test; those comparisons come from the vendor.
