Summary of UBS Global I/O Semiconductors Conference Call Industry Overview - The conference call focused on the semiconductor industry, particularly the advancements in co-packaged optics (CPO) technology as it relates to AI GPUs from Nvidia [2][3]. Key Points and Arguments 1. **CPO Technology Direction**: The industry is moving towards CPO as a key technology for cloud AI, with Nvidia indicating that its AI GPUs will utilize both copper and optics for interconnects [2][3]. 2. **Adoption Timeline**: - For scale-out interconnects between racks, Nvidia may begin pushing CPO switches from H226E for Rubin racks. - For scale-up interconnects within a rack, a hybrid approach may be adopted, upgrading NVLINK switches to CPO while continuing to use copper for GPU compute trays. - Full maturity for CPO technology for GPUs is anticipated by 2029E [2]. 3. **Impact on Copper Ecosystem**: Nvidia's comments are seen as positive for the copper ecosystem, indicating sustained demand for copper in the next generations of AI GPUs, while CPO may experience faster growth through market share expansion [3]. 4. **Foundry and Packaging Role**: TSMC is highlighted as a crucial player in enabling CPO technology through its manufacturing capabilities. An estimated 50% of Rubin rack shipments from late 2026E to 2027E may utilize CPO, leading to a demand for approximately 3 million optical engines (OEs) in 2027E [4]. 5. **Testing Challenges**: Testing CPO has been complex due to design intricacies and optical alignment requirements. Teradyne is expected to be a major supplier for CPO testing, with other companies like Advantest and Chroma also playing significant roles [5]. 6. **Stock Recommendations**: The report includes Buy ratings for several companies involved in the semiconductor supply chain, including TSMC, ASE, USI, KYEC, Teradyne, and Hon Precision [6]. Additional Important Information - **CPO Value Chain Suppliers**: A detailed list of notable suppliers across the CPO value chain was provided, including companies involved in epiwafers, fibers/cables, assembly, packaging, and testing [9]. - **Market Dynamics**: The report emphasizes the volatility and unpredictability of tech investments, particularly in the semiconductor sector, which may affect valuation and investment decisions [15]. This summary encapsulates the critical insights from the conference call, focusing on the advancements in CPO technology and its implications for the semiconductor industry and related companies.
