Smaller transistors make for faster, cheaper chips. Well, that used to be the case before AI came along and everything went a bit bananas. Still, a new report claims that TSMC is planning to begin manufacturing sub-1 nm silicon in 2029, which is kind of exciting.
There are few details in the Chosun Biz report other than the claim that their sources indicate TSMC is "set to begin trial production of sub-1-nanometer process semiconductors in 2029." Trial production does not mean chips you can actually buy, which would follow in 2030 or even later.
But given even the most advanced GPUs we can currently buy are produced on TSMC's fairly ancient N4 node, such as Nvidia's RTX 50 family topped out by the RTX 5090, which is itself derived from a 5 nm-class node, th...
