The expansion bus is PCI Express gen 3, which has a 40 GB/s bandwidth. System memory is accessed via a 4-channel DDR3 memory controller at 1866 MHz, delivering 60 GB/s of memory bandwidth.

External Thunderbolt 2 can be added, too. The number of Thunderbolt 2 expansion boxes available is increasing all the time, but two of potential interest are available from Sonnet Tech and site sponsor.

The box on the right, from, is the, which provides a single x16 PCIe 2.0 double width card slot at an affordable price point. For the Mercury Helios, OWC also provides a helpful instructional video that covers installation of a PCIe 2.0 card (specifically the, although the process is nearly identical for any standard PCIe card).

Thunderbolt 2 expansion chassis that are compatible with the Cylinder Mac Pro models (Late 2013, A1481) and the intended substitute for PCIe slots.

Time will tell if any company steps up and creates the generic Thunderbolt 2 to Thunderbolt 3 adapter that you are asking for. It would be a very difficult engineering challenge, and would almost certainly require heavily customized Thunderbolt firmware. I don't think many companies other than Apple and Intel have the expertise necessary. Such an adapter would probably be very expensive (~$100) and would consume a lot of power. The market for it is probably too small right now to justify the R & D investment. At time of writing, most Thunderbolt peripherals are Thunderbolt 1/2, Thunderbolt 3 only exists in a few docks and that one LG monitor. If a healthy ecosystem of Thunderbolt 3 peripherals develops, then it might make more sense to build this adapter.

And almost everything else is there as well: 802.11ac WiFi, PCIe SSD instead of the 'old' SATA III (6Gbps), which is another awesome and highly meaningful upgrade, but then. No Thunderbolt 2? No Thunderbolt 2???

Macbook Thunderbolt 2

I'm sure the next iMac spec bump will include TB2, but unless you're dying to drop another $3,500 on a 60hz 4K display after dropping $2,000 on the iMac itself, TB vs TB2 means very little. The real game changer will be when the iMac goes 4K or god willing 5120x2880 (not holding my breath, don't worry).

But you need Thunderbolt 2 support to run 4K displays. I guess I get it. Apple thinks desktops don't move a lot and that you already have a big high-res. 1440p display as part of the iMac. It's short-sighted in my humblest of opinions, and despite the fact that we know how Apple loves large profit margins, can it really be cost? Is it really going to cost even a cent more to buy a TB2 controller vs. The older TB1 version, especially since Apple worked with Intel on the technology itself?

The solutions in this article work with these Mac models, which have Thunderbolt 3 (USB-C) ports: • iMac Pro • iMac models from 2017 • Mac mini (2018) • MacBook Pro models from 2016 or later • MacBook Air (Retina, 13-inch, 2018) MacBook Pro (pictured), MacBook Air, iMac Pro, iMac, and Mac mini have multiple Thunderbolt 3 (USB-C) ports. If your Mac has only one port like this, it's a MacBook with USB-C. That port supports all but the Thunderbolt solutions in this article. MacBook has just one port, which supports USB-C but not Thunderbolt. IPad Pro 11-inch and iPad Pro 12.9-inch (3rd generation) have one USB-C port. Learn more about.

The Thunderbolt port on the new Macs is in the same location relative to other ports and maintains the same physical dimensions and pinout as the prior MDP connector. The main visible difference on Thunderbolt-equipped is a Thunderbolt symbol next to the port. The DisplayPort standard is partially compatible with Thunderbolt, as the two share Apple's physically compatible MDP connector.

Click to expand.The iMac performs better than the MacBook Pro's. I hardly call the 13' rMBP a 'Pro' device. The iMac still has better CPU, GPU, more RAM options (up to 32GB, while the rMBP is maxed at 16GB) The maxed out iMac is more Pro than the maxed out MacBook Pro. The iMac can be a great consumer device at standard configuration, but it can be a real Pro device once you customize it. Maybe I won't even use thunderbolt 2, but somehow it's strange that the MBP's are getting it and the new iMacs were left out.

The three terms associated with external device input and charging on the new MacBook Pro are being bandied about on the internet and social media, with a general lack of understanding. Couple that with a lack of user education, and you'd think that Apple omitting the USB type-A connector on the new machine is the end of the world, dooming all legacy peripherals to the trash heap, or similarly dramatic histrionics. USB 3.0, USB 3.1, and the USB-C connector In 2013, the USB Implementers Forum revealed the USB 3.1 connectivity specification, which doubled connection speeds of the older USB 3.0 to 10 gigabits per second with a new 'SuperSpeed+' transfer mode and a slightly modified Type B peripheral connector. This hurts now, but like other adapter crises before it drawing the ire of users, will pass in time. Shortly after announcement of the USB 3.1 speed boost, the same group announced a new physical connector with the potential for a symmetrical single cable to provide power not just to peripherals, but host device power as well—USB-C.
