Another Fact:
Forget doing DL on the Move if you can’t find a socket to plug in.
The GPUs on laptops are limited when on Battery. There isn’t a work around this, the Battery in my case can’t handle the maximum requirements of the 1070. I’m not sure but in most cases it should be the same.
It indeed is better than using a CPU. But it doesn’t help with, “Hm let me train this huge model while I sip on my coffee before a lecture”. You could probably do the Mini-Experiments that @radek has mentioned Here.
But beware, you won’t have full Power access when on the Move.
