> We're already seeing workarounds - graphics cards are using two, or even three PCI-E slots to get that precious bandwidth they need. With 4k displays on the horizon, and textures in games being updated accordingly, we're going to need more bandwidth to graphics cards. At some point, we're either going to have to switch to two dimensional connectors like processors are using for GPUs (which will still only delay our issues), or we're going to have to move away from the 1mm build fabrication for our interconnects. If the later happens, we simply can't rely on consumers to properly line up lanes in components.
They aren't actually using the slot, just potentially covering a slot right? One of the fastest desktop cards out, r290x only uses one PCI-E slot.
- oakwhiz 13y agoYes, every graphics card that I have seen merely occupies additional slots to make space for the cooling devices. However, I do believe that Nvidia's SLI and AMD's CrossfireX multi-GPU interconnects are a proprietary variation on PCI-E, so in some respects that could be considered an additional slot, but it only provides bandwidth between GPUs.
- jjcm 13y agooakwhiz is correct, I was wrong in my statements about cards taking up more than one slot. The blog has been updated accordingly. Sorry for the misinformation all, I could have sworn there were cards that did, but googling turned up nothing.

- stormbrew 13y agoThe bandwidth out of one PCI-E slot is pretty ridiculous on newer motherboards, even high end cards don't use it all. This is why things like those Thunderbolt PCI-E enclosures can even conceivably run a video card, since thunderbolt 2 is only equivalent to just over one lane of PCI-E 4.
