Cisco's 51.2T Silicon One P200 Chip Brings Scale-Across To Distributed AI
siliconANGLE, Wednesday, October 8th, 2025
Cisco Systems Inc. today announced its 8223 routing system, powered by its new Silicon One P200 chip - a new network system designed to unlock artificial intelligence's potential through massive scale.
Earlier this year, Nvidia Corp. introduced the concept of 'scale-across' architectures as AI is now hitting the limits of a single data center. A 'unit of compute' was once a server then evolved into a rack and then the entire data center. Scale across enables multiple data centers to act as a single unit of compute, and Cisco designed the 8223 and P200 silicon for the specific rigors of this task.
The new chip sets a new high-water mark for networking with a whopping 51.2 terabits per second of full-duplex throughput. There are two models of the new router. Both are 3RU and have 64 800G ports.
