Samsung comes in a close second in terms of tech. GloFo is also still floating around though lagging pretty bad AFAIK. Micron has it's own fabs that they are actively developing (in fact, they are building new facilities right now).
What TSMC is is cutting edge. That's why everyone that needs top performance uses them.
GloFo simply decided to stay at 14nm because beyond that, manufacturing costs actually increase, not decrease, and everybody wants the best, not second best.
They are now but they weren't always. I don't know much about hardware these days, I gleefully walked away from embedded development over a decade ago, but what I believe is that you don't really want to forecast to hard on any single player too far into the future.
Right but at some point does Nvidia use their muscle and block TSMC from making chips for anyone else? The demand for GPUs is just increasing too rapidly for this to make sense.
Apple was TSMCs biggest customer (25%) and nVidia is 2nd (12-15%). The bigger thing being that between the two, they lock up most of the bleeding edge process capacity and leave everyone else fighting over older processes.
Samsung is still in the game at the STOA level, but a distant second. But maybe it’s the nature of the industry that one winner takes all for a number of years at the top end. After all, Intel was the only game in town for decades.
