Not a bad idea however you have hard limits on how physically long the PCIe lanes can be. We had problems making sure we hit signal budget for a PCIe gen 4 slot on an ATX motherboard. The problem (PCIe lane length) gets worse as the speeds increase.

Yeah, I do that for a long time. Had a few accidents where I panicked until it turned out the card was just sagging and the PCIe connection was being stopped. After it happened the 3rd time I just cleaned up a little space and put the PC lying on its side. Zero problems since then.

I don't even understand what's supposed to be funny about this joke.

In reality, there is no reason GPUs should be add-ons. Just star designing motherboards with integrated GPUs of sufficient size. Case closed.

Every time I see the sizes of GPUs increase, I'm reminded of this from over 2 decades ago: https://vgamuseum.ru/wp-content/gallery/bitching-fast/bitchi...

The fact that even the “not to be sold in china” bit is so on point even today is kind of scary

I suppose you are not mysoginistic enough for the joke. I'd say that is a positive.

The GPU should be the motherboard, and everything sticks onto it.

So how would multi-GPU setups work?

You buy a motherboard with the number of GPUs you want on it.

Or maybe they could devise some sort of stacking system, with each GPU board separate and stacked.

My hope was it could similar length to today, just on the other side of the CPU.

Thinking about it though isn’t that where a lot of motherboards put a lot of their power regulation circuitry? I’m sure something would have to move.

But excellent point. That could easily bet a much bigger sticking point that I didn’t really consider too much.
