davide445 Posted June 21, 2015 Share Posted June 21, 2015 I did understand USB Type C need to implement an "alt mode" to carry on PCIe signals.This will need a laptop vendor to use extra hw components and not just sw? If a laptop does have a type c port that didn't implement the needed hw, a connected expansion card might be able to enable this feature? Link to comment Share on other sites More sharing options...
Dschijn Posted June 21, 2015 Share Posted June 21, 2015 USB 3.1 type C is just a plug, nothing more. The feature list is long, but the manufactures will have to implement the required chips inside the laptop to enable all the features.E.g. the 2015 12" MacBook is and always will be limited to USB (+power) and max 5Gbit/s. All expension cards will have to run through USB and can't just enable TB.I am pretty sure that Apple will adopt that plug for USB, TB and power. But they will have to make it easier to the customer to understand the ports, plugs and cables.E.g. - the 12" MacBook USB-C plug will never have a TB feature, until they release a new version of the MB.- the cables with the USB-C connector need to have a detailed list of what they support. The 12" MB cable can transfer power, BUT is limited to USB 2.0 speeds. TB3 will have a least 2 different types of cables with different speeds!

davide445 Posted June 21, 2015 Author Share Posted June 21, 2015 Meaning: eGPU useful Type-C connectors will be available only within the same expensive high end workstation grade or gaming laptop where you currently find TB ports?But you will need a TB alt mode to access PCIe bus or the implementation can avoid TB license costs and offer just access to internal bus, in the same way a regular expansion card can be simply connected to the slot?
