Google's TPU diversification challenges MediaTek and other ASIC partners

Google's push to diversify its TPU supply chain is a strategic hedge against geopolitical tech fragmentation. By bringing Samsung into front-end wafer production and adopting Intel’s EMIB packaging, Google is not only reducing reliance on Taiwan, China-based ASIC foundries but also forging a U.S.-Korea advanced packaging axis. This pressures MediaTek to urgently develop alternatives like CoWoS or FOPLP—or risk marginalization in the custom AI accelerator market. Compliance-wise, tightening U.S. export controls make single-region sourcing untenable; while multi-source manufacturing raises yield management costs, it drastically cuts off supply disruption risks. Competitors like NVIDIA and Amazon will likely replicate this playbook, accelerating non-TSMC pathways for their AI chips. Over the next 18 months, AI hardware supply chains will undergo de-concentration: geographic redundancy in both fabrication and packaging becomes mandatory, and mid-tier ASIC firms lacking heterogeneous integration capabilities face existential exclusion.
