You'd be looking for something with a discrete Nvidia graphics card with as many CUDA cores as possible.

Recommendations...depends on $$$...high end laptops are expensive as hell. Maybe something like a 1660 Ti?

Broadly I'd avoid ML work on a laptop though due to thermals

Unless you're trying to do ML with real time video or audio feeds, I'd just get a random cheapo laptop and do all your stuff remotely with something like jupyter notebooks (eg. Google Colab).

Having a remote GPU which is 10x more powerful than you can afford to buy yourself, and you can scale up to 50 GPU's at the click of a button is a far better workflow than spinning fans on your laptop overnight, only to wake up in the morning and realise a code tweak is needed and then you have to wait another 12 hours...

Get anything with a nvidia GPU. Without a nvidia GPU, it's pretty much dead

I wouldn’t go for a laptop for ML and I don’t care if CPU is Intel or AMD... parent commenter is mixing up CPU and GPU
