TSMC could start mass producing 1.6nm chips as soon as late 2026

6nm chip manufacturing process. The process is said to deliver an 8% to 10% increase in computing speed, and a 15% to 20% decrease in energy consumption. TSMC is expected to start mass production in Q4 2026.

While everyone’s excited about 2nm chips, IBM recently blew past that limit, showing off its sub-nm architecture . As a result, TSMC and other chip makers are now left playing a game of catch-up. However, IBM estimates that it will take five years before this design is ready for production.

As the company works towards that goal, TSMC is hot on IBM’s heels with a sub-2nm manufacturing process that could be ready for mass production soon. 6nm) process. TSMC will reportedly enter the mass production phase in the fourth quarter of 2026.
