3nm chips cannot be produced.
Qualcomm can't make 3nm chips, not only that, Qualcomm can't make any chips. Qualcomm has no chip manufacturing capacity, Qualcomm itself is a chip design company, the production of chips are looking for OEM, such as TSMC and Samsung is for Qualcomm Snapdragon chip OEM, so that can save costs. Samsung is the only company that can design and manufacture it.
