JPMorgan analysts report that NVIDIA's networking products, including Spectrum switches, NICs, and cabling, have a 90% attach rate with customers. This high attach rate is attributed to the increasing importance of rack-scale integration for efficiency gains in AI infrastructure, as raw transistor count alone is no longer the sole driver of performance. The analyst believes interconnect technology is becoming the primary bottleneck for next-generation AI, suggesting significant future growth for NVIDIA's networking division.
