Chipmakers Grapple With $6.3B Tariff Fallout as TSMC Doubles Down on U.S. Expansion

Round-up

  1. Nvidia Takes $5.5B Charge, AMD $800M From New U.S. AI Chip Export Curbs Washington’s updated licensing rules blocked Nvidia’s H20 and AMD’s MI308 AI chips from China, forcing immediate financial writedowns and sparking a 5% sector-wide stock plunge123.
  2. TSMC Accelerates U.S. Investment Amid Geopolitical Pressures The Taiwanese foundry is expanding its Arizona fab complex with an additional $100B commitment, aiming to diversify supply chains as China exempts TSMC-made chips from retaliatory tariffs45.
  3. JEDEC Releases HBM4 Standard to Feed AI/ML Bandwidth Demands The new HBM4 spec doubles stacked die count to 24 layers and boosts bandwidth to 2.4 TB/s, targeting 2026 deployment for next-gen AI accelerators6.

Other Developments

  • Lam Research donated a $40M advanced etch system to UC Berkeley’s nanofab lab to accelerate 2nm R&D7
  • Cadence acquired Arm’s Artisan foundation IP business to strengthen SoC design capabilities8
  • Huawei unveiled its CloudMatrix 384 AI accelerator using 100% optical interconnects to bypass U.S. export controls9
  • SEMI warned Trump’s proposed tariffs could cost U.S. equipment makers $1B+ annually10

Did You Know? The average AI training cluster now consumes 20-50MW of power – equivalent to a small city9.
