This discussion analyzes the evolving landscape of semiconductor networking and custom silicon, anchored by recent updates from Marvell and Broadcom. Ben and Jay review Marvell’s Industry Analyst Day, noting the company’s strategic pivot toward networking and optical interconnects over pure custom logic. They debate the technical and timeline challenges of shifting AI clusters from copper to optical (fiber) cabling, contrasting Google’s proprietary all-optical approach with the broader merchant market. The conversation then moves to Broadcom’s recent earnings, dissecting the market’s negative reaction to CEO Hawk Tan’s low-energy performance, the looming competitive threat of MediaTek at Google, and the complexities of modeling AI revenue. Finally, they close with a year-end review of AI stock performance, highlighting growing capital sensitivity and skepticism regarding the sustainability of current AI infrastructure spending.
