The firm has now moved a step ahead into the realm of AI infrastructure with the announcement of its Silicon One G300 offering, a 102.4 terabits per second (Tbps) switche silicon offering meant for the current AI infrastructure demand. Also, the firm has now introduced the N9000 systems and 8000 systems, along with other important AI infrastructure efficiency boosts.
Cisco’s declaration during Cisco Live EMEA 2026 marks a strategic initiative in the “Agentic Era,” a time during which AI applications are not only “trained” on a large scale but will be “running” on distributed computing setups.
At the core of this initiative is the Silicon One G300, built to power gigawatt-scale AI clusters for training, real-time inference, and distributed agentic AI workloads. With 102.4 Tbps switching capacity, the new silicon increases network utilization by up to 33% and can reduce job completion times by an estimated 28% helping organizations get more value from their GPU investments.
But Cisco’s vision goes beyond raw speed. The company’s Intelligent Collective Networking technology, integrated into the G300, combines large shared packet buffers, path-based load balancing, and proactive network telemetry. This helps data centers absorb traffic spikes, avoid packet loss, and maintain throughput even under heavy loads a frequent challenge in AI networking.
What Cisco’s Innovation Means for the Data Center Industry
Cisco’s new silicon and systems represent more than incremental hardware improvements they reflect a fundamental shift in data center architecture driven by AI.
1. Networking Becomes Central to Compute Efficiency
For years, GPUs and accelerators received most of the attention as the primary drivers of AI performance. Today, however, networking especially the ability to move data reliably and consistently between thousands of GPUs is increasingly recognized as a critical bottleneck. Cisco addresses this head-on with hardware designed to keep data flowing at scale, effectively making the network part of the compute infrastructure itself.
This shift underscores a broader industry trend: AI workloads are redefining what data centers must deliver. Traditional metrics like rack density or raw processor speed are no longer sufficient high-density switching fabric and optimized network telemetry are now core to performance. Cisco’s approach signals to the industry that future competitive advantage may lie as much in networking efficiency as in compute throughput.
2. Energy Efficiency and Sustainability Become Strategic Imperatives
The company’s novel Cisco N9000 and 8000 products enable the use of liquid cooling technology and feature “high density optics.” It is claimed that the improvements enable the enhancement of the energy efficiency of the product by as much as 70% compared to the previous versions, in addition to reducing the switch’s power consumption by as much as 30% using linear pluggable optics technology.
In an industry where costs are rising exponentially and sustainability concerns need to be addressed, significant efficiency benefits like these are welcome news. Hyperscale cloud providers and businesses around the globe face the need to address sustainability concerns, to reduce their footprint on the environment. This hardware can certainly help deliver that.
3. Programmability and Scalability for Future Use Cases
Another major advantage of Cisco’s G300 silicon is programmability. Unlike fixed-function networking devices of the past, these switches can receive updates and support new network functionality long after deployment. This extends the useful life of expensive infrastructure and helps ensure compatibility with evolving AI standards and protocols.
Additionally, Cisco’s integration of Nexus One, a unified management plane that consolidates silicon, systems, optics, and software, simplifies operations a crucial advantage for enterprises building distributed AI compute clusters on-premises, in the cloud, or across hybrid environments.

Broader Implications for Businesses
The importance of Cisco’s announcement goes beyond networking hardware. It reflects broader shifts that will reshape how businesses build and operate data centers in the AI era.
Enterprises Can Compete with Hyperscalers
Until recently, hyperscale cloud providers dominated large-scale AI workloads, thanks to vast resources and custom infrastructure. Cisco’s new silicon and systems give enterprises and regional cloud providers access to hyperscale-class networking capabilities, potentially narrowing this gap. This democratization of AI infrastructure can spur innovation across industries that previously lacked access to such capabilities.
Reduced Total Cost of Ownership (TCO)
Therefore, efficiencies in terms of data savings, equipment utilization, and management directly equate to savings in running costs. This could mean quick paybacks on investment for any business enlisting a data center or artificial intelligence computer system.
Enhanced Security and Operational Simplicity
Cisco has built-in security features in the hardware and enhanced its software capabilities, such as AgenticOps, which can potentially improve the product’s reliability and security, both being key concerns in industries such as finance, health care, and sovereign cloud.
Looking Ahead
Cisco’s Silicon One G300 and related systems have yet to be shipped by the company this year. This marks an important milestone in the company’s path to leadership in the AI networking space. As the use of AI continues to thrive and multiply the possibilities of various industries, such innovation in the world of networking will be critical.
In an era in which data center networking is no longer just a utility but a strategic asset, the latest inroads taken by Cisco herald the beginning of a new era of competition in the world of AI infrastructure.
