Nvidia, Intel Tout U.S.-Built Chips While Taiwan Remains Essential for Blackwell Packaging Until 2028

Nvidia and Intel are marketing domestically manufactured AI chips as proof of American supply chain independence, but critical packaging steps for Nvidia's Blackwell processors remain entirely offshore in Taiwan through at least 2028, according to Tom's Hardware reporting. The gap exposes a structural vulnerability in the claimed onshoring narrative: die fabrication in Arizona is incomplete without offshore assembly.

The 2028 timeline is a hard constraint, not aspirational. Nvidia cannot accelerate packaging domestization unless a U.S. firm invests $2-4B in new fabs and wins qualification—a 4-5 year cycle.

Intel faces the same wall. This means the Pentagon's AI infrastructure roadmap (Maven, successor systems, classified programs) assumes Taiwan-dependent Blackwell supply through FY28. If cross-strait tensions spike or Taiwan imposes export restrictions, the entire U.S.

AI advantage in autonomous targeting, ISR processing, and logistics optimization faces a 6-12 month sourcing lag. That's not a supply-chain story—that's a deterrence story.

WHY IT MATTERS

This directly contradicts the policy argument that underwrites CHIPS Act investment and export control strategy.

If Blackwell—Nvidia's flagship AI accelerator and the centerpiece of U.S. data center competition with China—cannot complete its production cycle domestically, then claims of supply chain decoupling are marketing, not engineering reality. The mechanism is simple: advanced packaging (chiplet integration, interconnect, thermal management) requires specialized equipment and labor concentration that Taiwan currently monopolizes.

Until 2028, every Blackwell unit leaving Arizona must return to Taiwan for finishing—creating a chokepoint that sanctions or geopolitical friction could exploit. This forces INDOPACOM and the Intelligence Community to assume Taiwan-dependent supply for the next 24+ months of AI capability buildout.

WHAT THIS DOESN’T TELL US

Does the article specify which packaging steps remain in Taiwan—flip-chip, ball-grid-array bonding, testing, binning—or is it a blanket statement? And does it name the specific Taiwan firms (TSMC's packaging division, ASE, Amkor) handling Blackwell, or only that the work stays offshore?
