Windows 7: Intel's Thunderbolt - (Light Peak) announced

If Nvidia or any other graphic card manufacturer were to do that without prior public announcement that would definitely alienate a lot of customers. The days of VGA is gone, isn't it? So I don't think too many in the Western world would be upset to see it no longer supported. Having said that, I still have a Philips 19" CRT tucked away; in case of emergency it can be used on my old Pent IV.

and you'll probably be able to buy adapters for a good few years yet..

Well, phasing out VGA is nice and dandy, but I have not yet seen one single projector in any university or conference using anything else. While the projectors themselves might have other connectors, no other cable is ever provided. As a result, everybody connects their laptops to the VGA port and Mac people use special adapters.

Naturally at home I am using DVI, but to be honest, I don't see a whole lot of difference between VGA and DVI provided the resolution is the same. Of course, Display Port is another matter, as it is supposed to be capable of higher resolutions. Right now I am using 1920x1200, which seems to be totally sufficient for the 24'' monitor, but should I go for a larger screen in the future, a higher resolution would be useful and thus I will need Display Port. At least that's how I understand this at the moment.

some interesting info in here
Thunderbolt (interface) - Wikipedia, the free encyclopedia

"A single Thunderbolt port can run up to six devices, including two monitors."

"...it has also been revealed that the technology will be exclusive to Apple until 2012"
Thunderbolt - more than a funky name - News - PC & Tech Authority

new macs with thunderbolt are already on sale
Apple - Mac

if light peak is a success then by 2012 there is the benefit that there will be alot of peripherals, at the moment there is no real reason to get a new mac since nothing available to the market supports it..

"It is important to also note that this isn’t the death knell for USB. Thunderbolt is targeted at devices with high bandwidth needs – an external hard drive, for example, is still limited by the speed at which its platters spin, and USB 3 has more than enough bandwidth for it."

either it will get replaced by thunderbolt eventually or it will be a fail and usb will keep upgrading

This is so far ahead of USB 3.0 that it isn't even funny:

Thunderbolt = Light Peak = Mini DisplayPort + PCI Express – Stephen Foskett, Pack Rat

Whoa there! So this little Mini DisplayPort connector includes 20 Gb/s of throughput in each direction, plus up to two DisplayPort v1.1a connections with 8.64 Gb/s each. This yields a grand total of 57 Gb/s over that slim wire. That’s one impressive interconnect!

With a legacy hub it will be able to fully support most existing devices. The speed is EASILY there and the design appears to accommodate it.

As mentioned, just about any existing PCI Express chipset can reside on this Thunderbolt bus, and the topology is extremely flexible. A Thunderbolt peripheral could be an endpoint, using the PCI Express lanes to drive FireWire, USB, Fibre Channel, or just about any other interconnect. It could also be a hub, allowing further Thunderbolt connections, or a pass-through in a daisy-chain topology.

I am not very happy with Intel that they provided exclusivity until 2012 to Apple. I hope that competitors challenge Intel on this score!

People are saying,, not too many people use Displayport's,,,,,,, I recall USB Ports were put on systems for literally a few years prior to USB becoming anywhere close to mainstream.
Also recall, that PS2 ports has only recently been discontinued on motherboards.

It took the industry a very long time to really see the potential or even tap that potential in USB.

So, this really isn't anything new.
Also note that PCI-E 1x has been on boards for a very long time, and very few things actually use it.

Don't know where the poster got 57Gb/s. From what I have seen from Intel it is 10Gbs in each direction and the bandwidth is shared by the DisplayPort and PCIe signals. Also I don't know what the deal between Apple and Intel entails. Since Apple owns Display Port maybe it is just the Light-Peak on Display Port connector that is exclusive. Intel wanted to use the USB connector but the USB standards group shot them down. Intel also wants to go fiber but other vendors wanted copper since it is cheaper. Light peak is here and will only get better this year.

He got it from here:

http://www.intel.com/technology/io/t...US_secured.pdf

... A Thunderbolt connector is capable of providing two full-duplex
channels. Each channel provides bi-directional 10 Gbps of bandwidth. ...


I agree with him that TWO full DUPLEX channels should result in maximum potential throughput of 40 GB.

BTW, here is an Anandtech quote supporting the claim:

Thunderbolt is dual-channel, with each channel supporting 10 Gbps of bidirectional bandwidth. That’s a potential 20 Gbps of upstream and 20 Gbps of downstream bandwidth.


I think that the author is right on target.

I found that Intel link a short while ago. Intel refers to it as 10GBs but then says it has 2 channels with 10GBs each which would be a total of 20GBs, however the original article mentioned 57GB which was in error.

Thunderbolt™ Technology.

Intel seams to imply that the max throughput to one device is 10GBs and the 2nd channel can handle another device at 10GBs.

Lots of assumptions on how this will play out but Intel has plans to upscale light peak to 100GBs using fiber. My problem is I cant type that fast.

I disagree. The original article was correct. It was talking about aggregate bandwidth of the interconnect and not necessarily to a single device.

.. this little Mini DisplayPort connector includes 20 Gb/s of throughput in each direction, plus up to two DisplayPort v1.1a connections with 8.64 Gb/s each.

Anandtech obviously agrees with it as well.

We will see who is right.
