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.
