Leaked Info on Third-Generation Thunderbolt Points to 40Gbps Transfer Speeds

Intel's third-generation Thunderbolt technology could see throughput increase to 40Gbps, double the current capacity of Thunderbolt 2, first introduced in Macs last fall, according to leaked information posted on a Chinese technology site [Google Translate].

Thunderbolt 3
The site says Intel's new Thunderbolt controller, code-named Alpine Ridge, will see power consumption reduced by 50 percent, support for PCIe generation-3, and charging capacities of up to 100 watts. Backward compatibility will be maintained through the use of connector adapters, but the new Thunderbolt connector itself will be reduced in size.

Last April, Intel first announced Thunderbolt 2 in April before seeing it move to the Mac in October. There is no indication of when the third-generation of Thunderbolt could make its way to consumers.

Thunderbolt 3 is nice but the Thunderbolt 1 ports in my 2011 iMac are still virgins. :o

Can't they just release 1 version and get it over with? All these revisions just make it impossible to take this technology to mainstream adoption. The biggest advantage of USB 2.0 wasn't the technology, it was the fact that it stuck around for over 10 years.

But i just bought a mac pro.


It's at times like these we do appreciate that the Mac Pro, being a professional computer, is expandable!

Oh, wait...

Why are they iterating so rapidly with versions of Thunderbolt?


Because no one is using it and Intel thinks that is because of speed?:confused:

Just make it affordable. All this speed means nothing if no one can afford to use it.

At first i was like wtf....i remember usb 2.0 being released to mainstream users in like 2003 and only now are we seeing usb 3.0 to be mainstream...meanwhile thunderbolt is getting new versions year over year.
at first i thought that sucks for developers and users/adopters/buyers...

but then i realized since the ports dont change and everything is backwards compatible.....this is actually good news.

Because when they showed the first version they said it was capable of 100 Gbps and that they would ramp it quickly. Which they are doing. They actually designed it to be much faster from the start instead of being pushed by other competing tech.

Yet another connector. Great.

Hopefully they at least make this one locking, like XLR mic cables. I'm REALLY TIRED of my Thunderbolt hard drives getting disconnected!!!!!

Apple is using slower technology in 2014 to transfer data between iPods and iPhones with computers than they were in 2001 (USB 2 vs. FireWire 400). Hope some of these technologies actually come to fruition eventually. If you fill an iPhone with video, it still takes a couple of hours to offload it.


Im surprised there is still no USB 3 for iOS devices, tho it seems apple has pretty much said screw syncing via wire.


The max theoretical speed of the cable is irrelevant when the limiting factor is the write speed of NAND flash inside your device.

Maybe I would be more excited if there were any accessories that I could use with the first generation Thunderbolt port.

Yeah yeah, I know there are a few accessories now, but they are all outrageously expensive.
