🔑 Enhanced Key Takeaways
- •MediaTek secured a $1 billion order from Google for TPU v7 chips manufactured on TSMC's 3nm process, with tape-out completed in September 2025 and mass production planned for Q4 2026[1].
- •Google is adopting a dual-sourcing strategy for TPUs, continuing with Broadcom for performance-oriented v7p variants while MediaTek handles inference-focused v7e, set for risk production by end of Q1 2026[3][4][7].
- •TSMC plans to increase CoWoS packaging capacity for MediaTek's Google TPU projects over sevenfold by 2027, from 20,000 wafers in 2026 to over 150,000 annually[3][4].
📊 Competitor Analysis▸ Show
| Feature | MediaTek (v7e/v8e) | Broadcom (v6p/v7p/v8) |
|---|---|---|
| Role | Inference-oriented TPUs, co-design | Performance/training TPUs, primary supplier[2][7][8] |
| Process Node | TSMC 3nm (v7e), 2nm planned (v8e) | TSMC advanced nodes (unspecified)[1][7] |
| CoWoS Wafers | 20K in 2026, >150K by 2027 | 200K pre-order in 2026 (+122% YoY)[4][7] |
| Timeline | Risk prod Q1 2026, mass Q4 2026 | Ongoing supply for current gens[3] |
🛠️ Technical Deep Dive
- •TPU v7 collaboration uses TSMC 3nm process for the chip, with MediaTek handling I/O modules for communication between main processors and peripherals[1][2].
- •TPU v8 planned on TSMC 2nm process, targeting 2028 launch, utilizing advanced CoWoS packaging technology[1].
- •v7e is inference-optimized variant, distinct from Broadcom's v7p training-focused version, supporting Google's diversification[7].
