But the CPU and chipset need to talk to all those ports. If any USB-C port can suddenly need to do Thunderbolt 3, that’s ridiculous bandwidth requirements. You probably can’t do that to 8 ports on anything.
- clhodapp 9y agoThis is exactly the sort of problem that tends to go away over time (often before it becomes an actual problem for very many people). The PCI-E and even RAM bandwidth of modern chipsets would have been absolutely astounding 10 years ago.
- Dylan16807 9y agoYou can share bandwidth among the ports. The default option for 8 ports would use 4 PCIe lanes for each pair of ports. But even full bandwidth for all ports is 32 lanes, not too hard to do.
- Filligree 9y agoHow many lanes does your CPU have?
- Dylan16807 9y agoNot enough, because it's six year old tech. But even my CPU could manage to have 8 lanes feeding a GPU and 8 lanes feeding a switch for the thunderbolt ports, something that provides enough bandwidth for the vast majority of use cases.
