Tsmc and Samsung are struggling with yield at 3nm. Will see whether Intel 3 can catch up.

How does one have leading edge volume and their high depreciation and still make the margins they do? Yup yields must be terrible, keep taking solace in that as you get a can of whoop a$$
"ChosunBiz reports that neither company is getting the kind of yields that you'd expect from a node that should have been in volume production for around a year by now, with Samsung apparently being somewhat better than TSMC. At 60 and 50 percent respectively, neither Samsung nor TSMC are anywhere near decent yields. Anything below 70 percent is considered very poor and even the 60 percent claim in Samsungs case, is apparently limited to some kind of Chinese mining ASIC and doesn't include the SRAM you find in most modern processors. ChosunBiz also mentions a source familiar with Samsung's foundry business who mentions a yield closer to 50 percent for the company. The same source also mentions that Samsung needs to reach at least 70 percent yield to be able to attract major customers to its 3 nm node."
So bad it will support Apple quarter billion phones ? And soon after that AMD, Nvidia, Qualcomm and Intel, terrible indeed
