Compared to AMD FX series, the Intel Core and Core2 were so superior, it was hard to see how AMD could come back from that.
Yup, an advantage in this industry doesn’t last forever, and a lead in a particular generation doesn’t necessarily translate to the next paradigm.
Canon wants to challenge ASML and get back in the lithography game, with a tooling shift they’ve been working on for 10 years. The Japanese “startup” Rapidus wants to get into the foundry game by starting with 2nm, and they’ve got the backing of pretty much the entirety of the Japanese electronics industry.
TSMC is holding onto finFET a little bit longer than Samsung and Intel, as those two switch to gate all around FETs (GAAFETS). Which makes sense, because those two never got to the point where they could compete with TSMC on finFETs, so they’re eager to move onto the next thing a bit earlier while TSMC squeezes out the last bit of profit from their established advantage.
Nothing lasts forever, and the future is always uncertain. The past history of the semiconductor industry is a constant reminder of that.
The thing is, if Intel doesn’t actually get 18A and beyond competitive, it might be on a death spiral towards bankruptcy as well. Yes, they’ve got a ton of cash on hand and several very profitable business lines, but that won’t last forever, and they need plans to turn profits in the future, too.
