Although it's only March, recent revelations about Apple's A17 processor have come one after another, with two rounds of GeekBench running points.

However, Revegnus, the whistleblower, pointed out that it may come as a surprise to some people that the yield of TSMC 3nm is not very satisfactory.

However, Revegnus, the whistleblower, pointed out that it may come as a surprise to some people that the yield of TSMC 3nm is not very satisfactory.

Although TSMC's manufacturing processes rarely failed in the past, a problem we have to face in the 3nm era is that the micro level is still FinFET (fin field effect transistor), which limits the 3nm to achieve higher density and lower energy consumption.

In fact, TSMC 3nm will also be the best FinFET. Samsung has switched to GAA transistors, and Intel will import similar RibbonFET transistors at 20A (2nm).

Previously, TSMC claimed to 3nm that it could save 35% of energy consumption, but it still needs to be told whether it can be done on the A17 and M3.
