Uh, but M2 on TSMC's N5 node is faster and more efficient than AMD's products fabbed with TSMC's N4 node. Edit: more efficient in general, but I meant "faster" in comparison with AMD's latest laptop chips.

Let's see what he has to say:

20% is quite a lot in the current competitive landscape. Jim Keller is stuck thinking like it's 10+ years ago.

- Kuinox 2y agoWe were talking about the M2. The M3 max is on TSMC N3B, which have a +30% of transistor density compared to the TSMC nodes AMD is using (N4).
