What is Apple - Thunderbolt and how it can work?

What at first seemed the most ridiculous of all the buzz surrounding the new MacBook Pro, is now almost a reality. Light Peak is ready for release and it is safer to do so tomorrow under the name Thunderbolt detected in the case of the new model of laptop. 

Apart from the fun of pronouncing the name invocásemos screaming as if some cosmic power, we know from the latest images Thunderbolt is not a completely new connection port but that is completely integrated in Apple's Mini DisplayPort with consequences that have not know. Does it? If we take a look at the patents that have been discovered recently about this, we can find out a bit about what we might see tomorrow explained in detail by Apple itself. 

If we join the little we know about the specifics, we can get an overview of the capabilities that can have that new port. Here we go. 

The expected arrival of a faster port 

 The arrival of a successor of the currently used ports, USB 2.0 and FireWire, seemed far away despite warnings in the form of rumors that reached us and promised their marketing in a short time . The tagline of "Yes, come, and it will Light Peak" has been used extensively to demonstrate exaggerated rumors not so long ago. But that, by the evidence, ends tomorrow.
Let's start with the specifications. Originally designed for use with optical fiber but made ​​from copper to speed their arrival, Light Peak promises speeds of 10 Gigabits per second in the short term and 100 Gigabits per second in the long run in both directions simultaneously. For comparison, the Firewire 800 port achieves speeds of 0.8 gigabits per second. 

But how will it behave in the Mini Display Port? When I saw how it was implemented I could not help remembering the outline of the rumor that we saw late last year: 

A patent to rule them all 

Not exactly the same because the scheme fuses including electric cable, but we could find a similar concept. Thunderbolt is fused to the mini DisplayPort port, which suggests an adapter cable to take advantage of new technology and at the same time to connect a screen. 

Why of course ... what will happen now with peripherals? Will he drives Thunderbolt? Camcorders Thunderbolt "? Has not heard of them, and USB 3.0 will have gained ground with the first compatible peripherals that interface. What I scale is the "Thunderbolt high speed i / o" photographed furtively Thunderbolt does not speak of "port", but Thunderbolt i / o. It sounds more like an improved system connectivity and ports of the Mac interface is not a new independent connection, right? 

Knowing that it is connected to the Mini DisplayPort, looking to a new version of that port with the addition of a new interface through which data can be passed in turn to a series of adapters might work faster. Who knows, maybe we find a way to improve transfer rates of our existing peripherals, with a high price but having to purchase more adapters.
The bit rate is what matters 

That said sospesa yet the possibility of a new connection interface. how much information passes through a data cable when using a screen like ... say the LED Cinema Display 27 " ? It seems silly, but if Thunderbolt anchu will share your bandwidth with other devices we can find surprises. I've been talking with Frikjan , friend and reader of this blog with experience in these matters, and the data is obvious: trying 3686400 pixels with peak light interface occupy almost the 10 Gigabits per second transfer of the cable (2650 pixels x 1440 pixels x 30 bits per pixel x 60 Hz are more than 8 gigabits per second, and the Light Peak interface uses more bandwidth). If we have to connect more peripherals, it will not be much available bandwidth for all data that have to be transferred. 

Unless, of course, that Intel and Apple have thought about this and have created a system whereby separate data transfer screen data peripherals can be connected through adapters. Anyway, knowing it is a laptop does not always have a screen connected to it and have incredible transfer speeds that are compatible peripherals.
