I’m looking to replace my sff J5040 Wyze machine. Its still plenty fast enough, but storage has become an issue with its limited USB endpoint availability of ~50 device limit.
I know that just switching it up to a newer Intel system could give me double the endpoints because of the two XHCI chip setup, but I was thinking that if I’m going to replace it, I’d like to not limit myself.
As such, even though Ryzen is far faster than I need, it does now support USB4. Does anyone know if the switch to USB4 would give the system a larger address range and have more than 127 USB devices or is that limitation still in place and I might as well not waste my money?
There was a recent video from everyone’s favorite youtube Canadians that tested how many USB devices you can jam onto a single controller.
The takeaway they had was that modern AMD doesn’t seem to give a shit and will actually let you exceed the spec until it all crashes and dies, and Intel restricts it to where it’s guaranteed to work.
Different design philosophies, but as long as ‘might explode and die for no clear reason at some point once you have enough stuff connected’ is an acceptable outcome, AMD is the way to go.
Nice!
The 127 endpoint limit isn’t even that hard, the spec is 127 endpoints per controller, however Intel appears to have done the dirty and restricted systems to 127, and even then you need two controllers to get that high. 😡
If AMD let’s us use multiple controllers to go higher then thats awesome, but its also following the spec.
[Edit] I’ll have to see if I can find the video.
I can save you the time there, at least: https://youtu.be/hiwaxlttWow
