Question about grapics cards.

[borisdarker]

So, since graphics cards have dyes, similar to CPUs why don't we have motherboards with a GPU socket. You could just buy the gpu, for example GP104 and put it on the Mobo and buy something similar to a CPU heatsink. Why doesn't this exist. Is there actually a technical reason?

GPUs use to be on the mobo itself, this changed when they became more powerful and needed more complex cooling solutions and more space on the pcb.

Because graphics cards are too big to fit in there? I mean, integrated graphics used to be in the chipset, later moved into the CPU to give more space for I/O ports and connections.

The main bulk of the graphics card is the PCB, as pointed out by the quote below here, they can fit on the board.

I still have a board with an integrated GPU on it haha.

 

OP: Mainly these two reasons

I didnt say it's heavy.

 

@borisdarker put it this way. If my 1070 is on the motherboard, the bottom half will be mostly occupied. My card is just a standard size 1070, so larger monsters will need even MOAR space

I didn't either, I was referring to the size itself.

but why not make wider boards with a GPU socket?

More expense, more complexity in the circuits meaning more room for error (mobos are complicated enough already), and then you’d be limited to only the GPUs for that socket, instead of being able to use any old or new GPU with a PCIe slot. Not to mention it wouldn’t look as cool.

wouldnt you have the benefit of having closer connection to the cpu because graphics cards have to talk through the PCIE slot

I don’t think that would make a massive difference, and imagine GPU makers working with mobo partners to push new sockets just so you have to buy a new GPU. Nvidia and Intel would be happy to do that.
