Marvell Technology Falls Over 3%. SemiAnalysis Says Co-Packaged Optics (CPO) Mass Production May Be Delayed to 2029, Nvidia Rubin Will Still Use All-Copper Solution.
TradingKey - On July 10, ET, Marvell Technology (MRVL) shares retreated, falling 3.38% to $235 as of press time. Reportedly, SemiAnalysis founder Dylan Patel stated that the large-scale adoption of co-packaged optics (CPO) may be delayed until late 2028 or 2029. Patel pointed out that current manufacturing yields, chip designs, and supply chain maturity have yet to reach the standards for mass deployment. Furthermore, Nvidia's Rubin and its subsequent Feynman architectures will continue to utilize all-copper solutions, meaning CPO on the GPU side will have to wait for several more generations of chip iterations.
