![]() Avoiding USB tunnelling might give higher USB transfer speeds since USB controllers of M series Macs are known to be slightly less performant. If a Thunderbolt 4 dock is connected to a Thunderbolt 3 port, then USB tunnelling will not be used and the Thunderbolt 4 dock's built-in USB controller will appear as a new USB bus and will get used as the bus that its hubs are connected to. Are you using a USB-C cable instead of a Thunderbolt cable? I suppose 20 Gbps is enough to get 5K60 10bpc since the Mac and display both support DSC (11.23 Gbps of DisplayPort data), but you'll get less than the max 10 Gbps USB write performance to devices connected to the Apple Studio Display's USB-C ports.Įven if the dock connects via Thunderbolt, the USB part of the dock will still connect to the Mac's USB controller (AppleT6000USBXHCI) since the Mac and dock support USB Tunnelling.Īny Thunderbolt 3 device with two Thunderbolt 3 ports, such as a Thunderbolt 3 dock, or a Thunderbolt 3 hard drive or PCIe enclosure. It looks like the Apple Studio Display is connecting at only 20 Gbps. This will tell you which ports are the fastest. I would use IORegistryExplorer.app to map where all the ports of the dock connect in the above tree (you need a USB 2.0 device to map the USB 2.0 part of the tree and a USB 3.x device to map the UsB 3.x part of the tree). The deeper the hub, the slower the performance might be but it's probably not noticeable. └─ 0x00242200 / 14 0x0066:0x0fd9 5 CalDigit CalDigit TS4 Audio - RearWhat's not listed is the ports that are unused in each hub.
