View Full Version : Apple's Thunderbolt for the video editor.
Michael Wisniewski February 24th, 2011, 09:14 AM So the new Macs have the Thunderbolt port (http://www.apple.com/thunderbolt/), and yeah there are no peripherals yet for it, but couldn't help getting excited over this blurb - If you’re a video editor, imagine connecting high-performance storage, a high-resolution display, and high-bit-rate video capture devices to handle all the post-production for a feature film — right on your notebook. And it also seems to explain why the Express Card slot was dropped from most of the Macbooks, apparently PCI Express is part of Firebolt. The other good news, simple adapters will allow you to connect USB and Firewire devices to the Firebolt connection. Good news for laptop editors.
Daniel Weber February 24th, 2011, 09:30 AM I think that it is called Thunderbolt...
Michael Wisniewski February 24th, 2011, 09:49 AM Yes you're right, it's Thunderbolt ... fixed that.
Zach Love February 24th, 2011, 10:13 AM I'm wondering how it will all shake out.
I have a MBP from 2007 & have feared upgrading b/c I'll lose my FW400 (nice for back up, or if I have 2 devices that aren't daisy chain-able) & most importantly the expresscard slot.
I'm hoping that vendors are already making expansion products, so I'm very interested in this.

Benjamin Maas February 24th, 2011, 11:59 AM Looks like the 17" MBP still has an express card slot on it.
Looks like it finally may be time for me to upgrade the laptop.

Evan Donn February 24th, 2011, 12:35 PM Interesting thing is one Thunderbolt port has almost the same throughput as all three pci-e slots in a mac pro combined (12Gb/s for the pci, 10 for thunderbolt). That's incredible for laptop expansion, but what happens with towers? I wouldn't be surprised to see a major refresh of the mac pros in the next year or two where pci is eliminated entirely in favor of a few thunderbolt ports... maybe even eliminate the internal drive bays and esata, you could have a very small 'mac pro mini' which basically housed power, processors, memory and a solid-state boot drive, then add whatever else you need externally via thunderbolt.
Edit: ok just re-did the math and realized PCI-E is still significantly faster... but I still think this is a realistic scenario. Thunderbolt is close in speed to a 4 lane card, so I think that would be sufficient for most existing cards - so if you had half a dozen ports on the back of a machine I don't think it likely that most people would ever hit it's limits.
I am a bit confused about apple's notes on the speed though - it says 10Gbps in both directions, then later it says "two 10Gbps channels on the same connector" and I'm not sure if they're referring to a single bi-directional channel or if it actually supports two independent channels. Intel's presentation today seemed to indicate two bi-directional channels per cable.
In any case this is an appealing upgrade for me... when I work at my desk I currently have to connect a DVI cable, fw800, and esata expresscard adapter - it would be great to drop that all to a single thunderbolt cable.
Thomas Smet February 24th, 2011, 05:00 PM I cannot remember where now but I read that Aja, Blackmagic and others were already working on devices to support Thunderbolt. I mean that was almost a given wasn't it?
Drive makers such as Promise and Lacie even already have working products which are being tested.
Expect NAB to be pretty hot this year with the rumor of the new FCS coming out soon as well.
Andrew Clark February 24th, 2011, 08:41 PM So for this ThunderBolt connection to work properly...does one need a "special" TB cable or can one utilize an ordinary DisplayPort cable?
Craig Seeman February 24th, 2011, 09:02 PM Thunderbolt is two channels of 10gbps each, each way (20 back and forth) but a device apparently won't be able to use both channels in one direction. I suspect this is part of the "management" which prevents speed degradation. Unlike other ports, this isn't slowed down by the slowest device on the port.
I've read that Intel also says that given that the controller needs direct access you won't be able to add a Thunderbolt PCIe card.
Yes Blackmagic and AJA as well as Avid and a few other companies have announced support. Lacie, Promise, Western Digital have announced support and I've heard Seagate will be supporting it as well. It might take until summer to see products though . . . just in time for everyone to have the new FCS (spring) and Lion (summer) on their systems.
I can definitely see Thunderbolt replacing Express ports as early as the next 17" MacBook Pro update. I suspect PCIe might take much longer . . . unless MacPros have multiple Thunderbolt ports. It really depends how widely it's supported and apparently Windows boxes wont have it implemented until spring 2012.
Keep in mind that there's a 7 device limit (I believe) and 3 meter copper wire (carries power) limit but optical cable will allow extremely long runs but won't carry power.
Thomas Smet February 24th, 2011, 09:19 PM The other cool thing about Thunderbolt is that it is backwards compatible with mini display port adapters. This is why it replaced the normal mini display port on the MBP's. You can use the port now just like you would with the older MBP. When we do start getting Thunderbolt devices you can still use the older adapters but you just have to make sure they are the last item in the chain. So for example use your mini display adapter to VGA as the last item in the chain.
I also read that there will be such TB devices as hubs and docks that can have many ports. For example FW800, USB and so forth. So if you have an army of FW800 drives you should still be able to use them. Of course all the MBP's still have USB and FW800 ports but it is just cool what can really be done with TB.
At some point in the future I could see computers having just one single TB port and then users can buy hubs with all the ports they would like to use such as FW800, ESATA, FW800, HDMI and so forth. We may even see a better form of external GPU's in the future that make use of TB. Imagine going out and buying an external gpu for your laptop when you feel you need a bit of a gpu upgrade. I know Nvidia and AMD have experimented with external GPU's for awhile now and so far TB seems to finally be a decent way of making it happen.
I don't think TB will ever take the place of true PCI-Express slots since in a MP they can be x16 slots which is much faster then TB. There are also some raid cards that need a x8 slot and TB doesn't have the bandwidth for those type of devices yet.
Andrew Clark February 25th, 2011, 12:40 AM So the hype / focus seems to be on the transfer speed and daisy chaining....but what about connecting this to a 30bit capable monitor?
Is the port / video card enabled to output in 10bit?
David Parks February 25th, 2011, 01:17 PM Being bidrectional is what makes it really impressive. I don't think this is hype, this is a big deal. New I/O standards that really work don't come around verey often. But when they do it can have a far reaching impact on how data is moved.

Evan Donn February 25th, 2011, 02:14 PM Is the port / video card enabled to output in 10bit?
Displayport can do up to 16bpc, but the actual capability would be dependent on the graphics card. I can't find any information on apple or amd's site about what the card can support.
David C. Williams February 25th, 2011, 06:32 PM Thunderbolt isn't a new I/O tech, it encapsulates current I/O, eSata, USB, whatever. It's basically designed to be a single cable and connector from device to device.
Kirk Candlish February 25th, 2011, 07:03 PM While also increasing throughput. It's faster than eStata, so it's not just incorporating it into a single cable.
David C. Williams February 25th, 2011, 07:13 PM While also increasing throughput. It's faster than eStata, so it's not just incorporating it into a single cable.
Thunderbolt has greater bandwidth than eSata, yes, but it can't magically speed up a single eSata based drive. It carries the eSata signal, that's all. The current Thunderbolt controller sits on a 4xPCI-e bus, that's the limit.
Thunderbolt isn't an I/O protocol, so you cannot make a Thunderbolt drive. It carries existing signals.
Kirk Candlish February 25th, 2011, 07:49 PM I wasn't saying it could affect the drive, not sure how that would be implied in my comment. The limitation is, as you said, the 4xPCI-e bus.
David C. Williams February 25th, 2011, 08:56 PM Well that's what you said. "While increasing through put"
Kirk Candlish February 25th, 2011, 09:33 PM Yes, to the bus.
David C. Williams February 25th, 2011, 10:25 PM What your suggesting makes no sense? It not speeding up any device, so there's no increase in throughput for anything. It won't increase the speed of an eSata to the PCI-e bus in any way. It just encapsulates the bus data and sends it down an optical fibre to be de-encapsulated at the other end and put on to another PCI-e bus.
How does that "increase throughput"?
Nigel Barker February 26th, 2011, 05:28 AM At the bottom of this page there's a video showing a demo of Thunderbolt in use on a new MBP connecting a Promise RAID array & monitor. It's pretty impressive performance. Intel Thunderbolt: a closer look (updated with video) -- Engadget (http://www.engadget.com/2011/02/24/intel-thunderbolt-a-closer-look)
Michael Wisniewski February 26th, 2011, 07:17 AM Thanks Nigel, that video put a big smile on my face. Now I'm thinking of all kinds of ways to max out the Thunderbolt technology.
Bob Willis February 26th, 2011, 08:29 AM Thunderbolt Device:
LaCie is the premier manufacturer of high quality digital storage. (http://www.lacie.com/us/index.htm)
This is more than just a cable. 2 Bi-directional 10Gb/s channels. Now that is increased throughput.
800 MB/s of performance

Andrew Clark February 27th, 2011, 03:48 AM So this should work the same when using with Windows 7 Ultimate 64bit (via BootCamp of course)....right?
Nigel Barker February 27th, 2011, 04:17 AM Microsoft would have to support Thunderbolt in Windows first & the 3rd-party manufacturers would have to write drivers for their devices. I am sure if Intel have their way this will happen but I don't think that there is any support at present.
Dom Stevenson February 28th, 2011, 02:46 PM I'm interested in the 13" MBP. Any ideas how much of a difference the integrated graphics card would be compared to the 15" AMD standalone card?
I'd rather save the cash and get a nice monitor and thunderbolt friendly external HD than pay the extra 500 quid for the 15.
Zach Love March 1st, 2011, 01:20 PM I'd be interested in this too.
I opted for a 13" at work since I have a Mac Pro which I'm at for 90% of the editing I do & knew that 90% of the work I'll do on the laptop won't be long hours of editing, so I wanted something that was a little smaller & easier to carry around.
My personal computer is an older 15" MBP, which is excellent, but I do like the smaller size of the 13".
When I upgrade my personal laptop, I'll have to decide if I want the portability (& extra cash) or if I want the higher quality video card, so it'd be great to see how great the advantages are for the money.
Kirk Candlish March 1st, 2011, 01:29 PM You guys can easily find reviews of the new MBPs all over the net. A good place to start would be macworld.
Kirk Candlish March 1st, 2011, 10:31 PM appleinsider has a good article on the new MBPs.
One quote from there:
"Thunderbolt is like a very fast FireWire, with an improved connector, high resolution external display support, and more electrical power, with support for Target Mode booting and the ability to bridge other interfaces, including Ethernet and USB. "
Worth the time to read and a good site for lots of information.
Jonathan Shaw March 3rd, 2011, 11:30 PM I was literally about to purchase a Thecus RAID tower which would connect via ethernet. Do you guys reckon that Thunderbolt will have a big take up and will it be that much better performance??? Lots of if's and maybe's I know.
Nigel Barker March 4th, 2011, 01:05 AM I was literally about to purchase a Thecus RAID tower which would connect via ethernet. Do you guys reckon that Thunderbolt will have a big take up and will it be that much better performance??? Lots of if's and maybe's I know.If you are considering a Network Attached Storage (NAS) device then performance of Thunderbolt is moot as you can already have a faster connection via Firewire or e-SATA. NAS is convenient & has reasonable performance but is not the high performance option.
Jonathan Shaw March 5th, 2011, 05:17 PM Sorry to sound dumb but why is NAS not that high performance, I thought over ethernet it would be quick. Would it not be quick enough for editing?
