Wrong! 10 Nm CPU is good enough for all you want to do with a Desktop or Laptop.
But 7NM (TMSC can do this) and less, is what the obsessed need for their phones and tablets. Lower power and battery draw. Do they do anything useful in the work world?\\\\ No!
\I just looked at my Phone ..10 Nm chip... My phone https://www.gsmarena.com/samsung_galaxy_a51-9963.php
It isn’t good enough for anything but a desktop if buying new. Laptop battery life is better on 7nm chips (in general). Considering that business is increasingly moving away from desktops and towards laptops and tablets.... Not sure you get where tablets don’t do anything useful in the work world.
And in the end, if you are a chip company and you’re stuck with 14nm+++/10nm like Intel is... well, you have problems right about now.
