  • Inside Apple's 2016 MacBook Pro: USB-C and Thunderbolt 3

    I hope all 4 ports will be full capacity Thunderbolt 3 ports! I guess there might be a total bandwidth limit to what the portable version of Kaby Lake can actually pull off. 40Gb x 4.. is that within the specs? Would be awesome.
    4 Thunderbolt 3 ports would require 2 separate Alpine Ridge I/O chips; most laptops have only 2 Thunderbolt ports because that is all the Thunderbolt 3 chip supports.

    There could be 2 Type-C connectors that are charging/USB only, leaving the other 2 for be all inclusive Thunderbolt/USB/display etc.

    One thing of note that will make things confusing. The only thing guaranteed by a Type-C connector is USB 2.0 performance and power. Anything else is optional:
    - USB 3.1 gen1 (essentially USB 3.0 spec)
    - USB 3.1 gen2 (the 10Gbps flavour)
    - DisplayPort
    - Power Delivery for charging (note, there are several flavors of this, too)
    - Thunderbolt 3

    I expect "it just works" will be hard to achieve, as simply having a Type-C connector, there is no guarantee of the capabilities without some intelligent labeling. I know that Intel has required certain superset of capabilities if the Thunderbolt logo is used on the connector.
