You've posted this in the laptop section.....

What are you looking to do, specifically? Adding a GPU to a laptop is not usually an option.

As for PUBG mobile, assuming you're running the emulator?

1GB GPUs are pretty dated at this point and, while relatively cheap to pick up used..... why wouldn't you look to a more modern GPU (say a GTX 750TI or 1050 or something) instead?
