TSMC begins quietly volume production of 2nm-class chips — first GAA transistor for TSMC claims up to 15% improvement at ISO power

TSMC has begun volume production of 2nm-class chips using its N2 fabrication process, which promises a 10%-15% performance gain at the same power, a 25%-30% power reduction at the same performance, and a 15% increase in transistor density compared to N3E. The N2 process features gate-all-around (GAA) nanosheet transistors for improved electrostatic control and reduced leakage. TSMC plans to ramp up production at new fabs for both smartphone and larger AI and HPC designs, with N2P and A16 versions scheduled for production in the second half of 2026. The company aims to offer enhanced performance and power benefits with these new iterations.
