Sources: China's Oppo is developing high-end mobile chips, using TSMC's 3nm tech, for its premium handsets due out in 2023 or 2024
China's top handset maker looks to use TSMC's cutting-edge 3-nm tech — TAIPEI — China's leading smartphone maker Oppo is developing high-end mobile chips …
Context & Ripple Effects
Oppo's reported 3nm project marks an ambition to move from buying handset silicon to controlling a premium-chip roadmap with TSMC. It later delivered a narrower but concrete step when it introduced the TSMC-made 6nm MariSilicon X imaging chip.
The effort places Oppo in the same leading-node supply chain Apple was also targeting for its A17 and M3 chip plans. It also anticipates a broader Chinese handset push toward self-designed silicon, later reflected in Xiaomi's reported chip program.
First-order effects
- Oppo gains a prospective route to differentiate its premium handsets with internally developed silicon, while TSMC adds another reported customer for its 3nm process.
- TSMC's leading-edge production is positioned to serve both Oppo's reported premium-chip plans and Apple's planned 3nm products, making access to that process a near-term constraint for handset chip roadmaps.
Second-order effects
- Merchant mobile-chip suppliers face more pressure from handset makers seeking control of key components: Xiaomi's later program was explicitly aimed at reducing reliance on Qualcomm and MediaTek.
- Oppo's subsequent 6nm MariSilicon X launch suggests a staged in-house design strategy, in which specialized chips can establish design capability before a reported high-end mobile processor effort.
Third-order effects
- Chinese smartphone brands are increasingly treating custom silicon as a strategic layer of handset differentiation, although their manufacturing paths may diverge between TSMC and domestic foundries such as SMIC.
- Competition for advanced-node capacity is likely to become more tightly tied to device makers' chip-design plans, rather than only to established merchant-chip vendors' orders.
The trend: Premium smartphone makers are bringing more chip design in-house while competing for access to the most advanced foundry processes.
