> Compared to 5nm process, the first-generation 3nm process can reduce power consumption by up to 45%, improve performance by 23% and reduce area by 16% compared to 5nm, while the second-generation 3nm process is to reduce power consumption by up to 50%, improve performance by 30% and reduce area by 35%.

What kind of real-world impact are we likely to see on the 3nm chips for the new iPhone and M3 macs? These figures seem outstanding and generationally impactful if true.

To be clear, you don't get all three.

Also, are these Apple's numbers? They are better than what TSMC say (1st gen) 3nm silicon provides:

> N3 technology will offer up to 70% logic density gain, up to 15% speed improvement at the same power and up to 30% power reduction at the same speed as compared with N5 technology

Why hasn't Apple just bought TSMC?

It's hard to imagine that they'd be allowed to. Beyond that though, I think Apple's strategy is to create a monopsony for high end parts (ssds, displays, etc). Buying TSMC would work against that.

Given how expensive (and risky) chip fabrication is at the cutting edge doesn't it make more sense to just pay extra to use whoever has the cutting edge node and not take on the R&D risk?.
