How do mobile GPUs work?

Zomb0matic · Feb 13, 2017

I've never opened up a laptop nor do I really intend to, but I was just curious. How does the GPU in a laptop work? Is it soldered onto the motherboard, or does it use some other interface other than PCIE?

Typically mobile GPUs are integrated into the the motherboard PCB so don't run via PCIE. You will probably be able to find a fair few videos on youtube showing you the internals of Gaming laptops with mobile gpus

Most are just soldered on to the board. a smaller amount use MXM cards, which is similar to a pci-e card but for laptops.

it can be soldered or connected via PCIe (in different form factor)
depends on the manufacturer choice

this mxm thing looks interesting. im guessing only a few notebooks use that though, so there won't be upgrading old laptops with new 1080s anytime soon. thanks!

Yeah tends to be only the higher end larger laptops.

Some motherboard manufacturers are experimenting bringing this connection method to small form factor desktop pcs also:

which was also watercooled. Honestly, I was very impressed by engineering of that unit.
AFAIR, Linus took one apart.
