@kaia @Error the whole south/north bridge thingie is mostly outdated. and also only important for amd/intel products. it was true before pci was even a thing. i think it is mostly for integrated gpus or if the gpu is connected via the old agp thingie rather than pci-e

@kaia @Error (technical person) Why is there a DDR5 in a platform old enough to still have a northbridge?

@kaia @Error This isn't accurate to most desktops now: the north bridge is integrated, but the south bridge usually isn't. Most desktops will have one or two PCIe slots wired straight to the CPU, and the others go through the south bridge (which itself connects to the CPU via PCIe as well)

@kaia @Error there are some PCIe slots that are provided directly by the CPU and some that are provided by the chipset. More often than not the former includes the slot where the GPU resides and nowadays also sometimes a M.2 slot. And also more another PCIe "slot" if the CPU itself provides USB4 and thus PCIe tunneling. 🤔

@kaia @Error interestingly, this graphic would have been more accurate if the GPU was marked "AGP" and it had PCI instead of PCIe. Back in the AGP days, the GPU really did have its own special bus connected closer to the system RAM.
