1239 ET - A look at hyperscalers' most recent earnings suggests that the momentum behind custom silicon chips, or ASICs, remains strong, creating upside potential for custom chip makers Broadcom and Marvell Technology, JPMorgan analysts write in a note. Google's most recent results suggested continued investment in its internal TPUs, they note, while Amazon "was much more explicit in validating the custom ASIC thesis" in touting demand for its Trainium chips. "AI infrastructure is becoming increasingly heterogeneous, with hyperscalers optimizing across GPUs, custom AI ASICs, CPUs, networking, and connectivity to improve TCO, performance per watt, supply assurance, and workload-specific efficiency - all of which are highly supportive of our top picks: AVGO and MRVL," the analysts write. Broadcom ticks up 0.4%, while Marvell trades up 5.6%.
