We've yet to see any 2 nm chips make it into our PCs. Actually, there aren't many 3 nm chips yet, just Intel's Arrow Lake and Lunar Lake CPUs. But TSMC is marching on to the next jump in chip tech, and nominally 1.4 nm transistors, by accelerating its plans for new factories that will see the new silicon production node come online in 2027, with full mass production beginning in 2028.
According to Taiwanese outlet UDN (via TechPowerUp), TSMC has made a "major breakthrough in the advancement of its 1.4 nm process." In line with Intel and its 18A and possible future 14A nodes (the latter is now at threat of being cancelled if Intel can't find some customers), TSMC refers to its 1.4 nm process in terms of angstroms, branding the new node A14.
