    Anyone knows why the new 2017 Kaby Lake Macbook 12 does not have Thunderbolt 3 and is still stuck with inferior USB-C? :(

    Ask Apple. If you want TB3, spend a little more and get the 13" MacBook Pro. It's not as thick as the MacBook, but it's still incredibly thin ... thinner than the Air.

    Its not about money. I tried Macbook Pro 13. It can't compare to Macbook 12. It is heavy, noisy and simply too bulky.

    3 pounds isn't exactly what I'd describe as heavy ... and it's only a pound more than the MacBook. And thick? It's thinner than the Air at half an inch. Regardless, you're not going to get TB3 on the MacBook anytime soon. Would be nice, though.

    Does the low power Kaby Lake have the TB3 controller on chip like the desktop version?

    built in? no. they would still need the alpine ridge controller to accommodate TB3 (which the MBP does for their skylake processors). i highly doubt Apple would want to redesign their already tiny PCB to allow TB3 on what is a minor spec update to the MacBook.

    i believe TB3 will be supported on the low powered chips in Coffeelake, so *maybe* we can expect TB3 to show up then.

    to be honest, i don't see a need for TB3 (which is geared towards more pro users) on the MacBook. What Apple should have done is at least update the USB-C standard to 3.1 gen 2 (10Gbps bandwidth). I have no idea why they are still stuck on gen 1 (5Gbps) speeds.

    Just looking at the specs, yes, but in practice it's really noticeable. And the Air is at least tapered, which the MBP isn't, and that completely changes the way it feels and how you handle it.

    I agree. It's like paper thin at the thinnest end. The MacBook feels like nothing.

    You'll probably have to wait until Intel integrates the controller into Y-series processors.

    40 Gbps bandwidth.

    How much slower is TB2?

    20 Gbps, so half as slow.

    Glad I came across this as I'm debating between the two for my gf. Will go with the base MPB since it's basically the same $ amount for both

    Just be aware that the base MBP has 128 GB of non-upgradeable storage.

    Next Coffee may provide as Intel build the controller inside.
    I'm unhappy this year MB12 don't upgrade to TB3 and P3 display.

    Also they actually can introduced 14" MacBook system use some board as MB12
    with large battery and display, lighter and thinner that 13" MBPR.

    Small amount of storage is not really a problem anymore with the rise of cloud storage. But agreed, I will likely upgrade it to a 256GB for ease of mind.

    Well, to be honest for me tb3 si a game changer. Bascially you can travel with the compact MacBook 12 and at home attach it to a dock which is capable of VR and has all the ports you need.

    I use the mb12 for lightweight video editing and it works perfectly. Just the export is painfully slow. With tb3 you can edit on the go, attach it to the dock at home, and export fast with the help of an external gpu.

    The problem is that Katy lake has no native tb3 controller. Definitely looking forward to coffee lake.

    Because the standard Kaby Lake chipset does not support TB3 natively. Apple would need to add a second chipset, which would require a more thorough redesign to accommodate the extra heat generated. My guess is that we won't see Thunderbolt until the first "major" redesign.

    As far as I can tell, Coffee Lake won't have Thunderbolt 3 onboard either. Can you point to any sources indicating that it will?

    Intel has promised to integrate Thunderbolt 3 into its CPUs but it doesn't say which ones. It's not clear that something that has TDP 4.5W might have it. The current Intel Thunderbolt 3 controller has a TDP of 2.2W. Even if made more efficient, that'd still be a substantial penalty.

    I suspect if you want Thunderbolt 3 in a 5W CPU, you may be waiting a couple of years, so around 2019 perhaps.

    Mhmm... then whatever lake it will be: looking forward to tb3 on the MacBook! It will be the ultimate machine.

    I agree about that. Two TB3 USB-C ports (since the controllers support 2) and better cooling. But it won't happen.

    One is enough for me. my dream docking station would be a combination of the owc tb3 dock with all ports that my mini 2011 already has, plus a slot for a gpu. No need for a second port. When traveling I do not need a second port...
