Its about the same size. The screen, keyboard, trackpad... all comparable. It has more ports. The cooling system in the G14 blows the mac away, hence it can run passively and sip battery just piddling around the desktop.
The mac has 3 big advantages as far as I can tell:
- Power efficiency under heavy GPU/AI loads. If you even sniff the dGPU in a PC, you can kiss your battery goodby.
- A large RAM pool for GPU/AI stuff.
- No fussing around with different power settings/fan profiles for different situations.
As for the PC laptop
- It has a huge gaming advantage
-"native nvidia" is often easier for ML stuff.
Software differences are a whole other can of worms.
