> A laptop that can match the best of the competition's desktop is pretty big advantage IMHO. 7945HX3D (a 5nm 55W laptop part) scores 15-16k on GB6. M3 Max 3nm is just a little better. Almost all of which can be attributed to TSMC 3nm.

Sure, if you define "a bit" to be %30 then you can say that. Not everyone will agree with the "a bit" definition though, how many years took AMD to hit a %30 improvement? Also, the high performance laptops with that chip appear to be %50 heavier than 16" Macbook Pro. According to reviews, those laptops can do 4 hours of general usage(not gaming) at best - so terrible battery life. Also, significant drop in performance when unplugged. Overall, those machines are optimised for one thing only and apparently they can do it about %30 worse than a Macbook and everything else much, much worse.

  > Sure, if you define "a bit" to be %30 then you can say that. 30% is roughly the difference to be expected between N5 -> N5P/N4 -> N3. That was the original argument - "TSMC". About laptop battery life etc, that's a different discussion.

Keep in mind that predicted power and performance improvements keep the other factor constant. https://www.anandtech.com/show/18833/tsmc-details-3nm-evolution-n3e-on-schedule-n3p-n3x-deliver-five-percent-gains https://www.anandtech.com/show/18833/tsmc-details-3nm-evolut...

  For how long can the macbook do the 30% more? Because in my experience as someone who renders animations for multiple days or even weeks on machines, the newer Apple designs are good for burst loads, but don't shine when it comes to continous loads where the thermals start to kick in.
