Impact U.S. Chip Curbs
In April, the U.S. government imposed new export controls prohibiting the shipment of high-bandwidth memory (HBM) GPUs to China, effectively sidelining Nvidia’s H20 chip. As a result, Nvidia incurred a one-time $5.5B write-off of inventory in the April quarter, and Jensen suggested they’ll lose about $15B in sales this year. Deepwater estimates that about 25% of Nvidia’s FY25 revenue, or $50B in CY25, was effectively China-related. That means that about $20B has been going through authorized channels of H20 sales, and another $30B has been going to third parties, many stationed outside of China, that supply China with Nvidia GPUs. In other words, putting curbs on H20 only partially fixes the problem of China’s access to the most advanced GPUs.
To recapture this revenue segment, the company is reportedly fast-tracking a “Blackwell-lite” chip that could ship as soon as June. Each quarter that “lite” chip is in the market, would add back about $5B in revenue.
Some specifics: For the July guide the buy-side models have already marked revenue estimates down to roughly $38B, down $7B vs. the imprint estimates of $45B, to reflect the U.S. curbs.
