What happens if I plug a PC into another PC via thunderbolt?

Something I really wanted is, when I connect my laptop to my home computer, my laptop can use the home computer's CPU, GPU and RAM and have an additional screen.

I believe Thunderbolt will make this dream true, since the Intel page mentioned "workstation performance expansion".

It really seems to me a lot of this is about making your current peripherals obsolete so they can sell you new ones.

In the long run, Thunderbolt aims to replace USB, FireWire, Ethernet, DisplayPort/HDMI/etc, eSATA and be considered an external variant of PCIe. This is feasible and would be a good future, just like the future we live in now where USB has replaced serial ports, parallel ports and PS/2.

The weird thing is that there already is an external cable for PCIe. An 8-lane PCIe cable can beat Thunderbolt, at 16Gb/s instead of 10. (Although I'm not sure if that's bidirectional; if not, you'd have to go to a 16-lane cable.)

I am delighted that Thunderbolt isn't reusing the USB plug form-factor. Early rumors showed Light Peak plugs that were the standard rectangular USB shape with fiber optic channels blended in: http://www.macrumors.com/2011/02/19/apple-to-introduce-light... The outer rectangular, doubly symmetrical shape of USB is a usability nightmare! You know what I'm talking about. Good riddance.

Yes.. 50% chance of getting it right every time, even though it feels like less than that! It doesn't help that some motherboards put the USB ports upside-down for some inexplicable reason, and when it's dark you can't see the little USB logo on the cable anyway.

Oh, it's not so bad once you take advertising sub-clause of the spec into account. That's the hidden clause that states the USB logo will be on the top of a properly-oriented plug unless you're Microsoft or Logitech, in which case your corporate name is allowed top-billing, so to speak.

Of course, if the slots are oriented vertically...

> Electrical or optical cables From http://www.intel.com/technology/io/thunderbolt/index.htm I don't know what that means though. Does the newly released MBP support both or only one?

Light Peak right now is only copper. Optical will be added in the future most likely.

I'd like to read about this. Is there an available document explaining why? Or do you know the reason?

(Not that I hate copper or anything, it is just that they designed it for fiber from the beginning and then suddenly bailed out)

With vertical plugs I always just plug it in whichever way I'm holding the plug first, then flip it as necessary. It's not like there's any standardization between motherboard manufacturers on this, so why bother trying to remember which way it goes?

Hopefully the same as when you plug a Mac into another Mac via FireWire. (One of the Macs becomes the most expensive external HDD ever. This requires one Mac to reboot into the target disk mode. It would be nice if the same trick would be possible with Thunderbolt without rebooting.)

Thunderbolt aims to replace nearly every kind of single-use connectors (HDMI, DisplayPort, eSATA, USB, Ethernet). Unifying the connector for displays, peripherals, network and power is a great idea, so I can't complain if they're going up against USB 3.0.

Ha. Good luck to them. Thunderbolt will be lucky to replace firewire. There's no way in the world it can replace USB, Ethernet or HDMI. Just think of the number of devices out there with these ports. It might replace SATA eventually, but it will have to fight against USB.

It this a qualified statement or are you just guessing?

Well possibly, if it's in displayport mode using all four lanes in one direction, it can push that much bandwidth. How much bandwidth does a 27" apple display use?

Well, let's see: 2560 x 1440 resolution at 24 bits per pixel = 88,473,600 bits At 60Hz, that's 5,308,416,000 bits per second. So a little more than half the claimed 10Gbit bandwidth of Thunderbolt. I guess you're not going to be running two of them on the same port.

Depends on what you're using it for I guess. For my typical day coding / web browsing / etc. I'd rather run two at 16bit instead of one at 24bit.

If I was editing movies it'd be a different story.

Anybody notice how it shares the name with HTC's 'ThunderBolt' 4G phone being released, and how it looks like both Intel and HTC have trademarks on the word?

It's perfectly reasonable for two entities to have trademarks on the same word, so long as they aren't in the same business. In this case (without looking at the relevant legal paperwork), HTC could trademark 'Thunderbolt' with respect to phones, mobile devices, whatnot, while Intel may have the trademark with respect to peripheral data connections. Nobody (except maybe Monster Cable) would have an issue with that arrangement.

Has anyone considered using an external video card with this? That would be a great use with desktop replacement laptops since it would actually be upgradeable.
