Cisco Introduces Silicon One G300 Switch
8.9
Cisco is introducing Silicon One G300, a high-performance switching silicon delivering 102.4 Tbps, 1.6T Ethernet port support, a 252MB shared packet buffer, and up to 512-port scaling, with an SDK available and first systems targeted for 2H2026. Cisco reports simulations showing 33% higher throughput and 28% faster job completion times, positioning the chip to lower TCO for large GPU clusters.
Key Points
- 1Announces Cisco Silicon One G300 delivering 102.4 Tbps switching and 1.6T port support
- 2Highlights 252MB shared buffer and path-based load balancing to reduce congestion and latency
- 3Enables up to 33% throughput and 28% faster job completion, lowering TCO for AI clusters
Scoring Rationale
Significant silicon upgrade promising throughput and TCO gains; claims rely on vendor simulations without independent benchmarking.
