With PCIe being so limited, there's such allure to having two USB4 ports! But will they work? IIRC we saw similar very low bandwidth on Apple's ARM chips too. This was during M1 or so; dunno if things got better with that chip or future ones! Presumably so or I feel like we'd be hearing about it, but also, these things can just go so hidden! It was really cool back in Ryzen 1 era seeing their CPU get some USB on the cpu itself, not have to go through the IO/peripheral Hub (southbridge?), with its limited connection to the CPU. There's a great up breakout chart here, showing both the 1800x and the various chipsets available: relishable data. https://www.techpowerup.com/cpu-specs/ryzen-7-1800x.c1879 https://www.techpowerup.com/cpu-specs/ryzen-7-1800x.c1879 I feel like there's been some recent improvements to USB4/thunderbolt in the kernel, to really insure all lanes get used. But I'm struggling to find a reference/link. What kernel was this tested against? If nothing else, it's be great to poke around at debugfs, to make sure it's getting all the lanes configured. https://www.phoronix.com/news/Linux-6.13-USB-Changes https://www.phoronix.com/news/Linux-6.13-USB-Changes
