YES PLEASE!

I would pay good bucks (like 300ish) for an "all in one" solution that would expand on your portable.

When i first saw Thunderbolt, I thought it would be the perfect device for laptops. What i envisioned is a breakout box with the ability to include 1 or 2 PCI-e devices (such as video card). but also had on it a USB hub, Gigabit ethernet, and other assorted plugs your desktop might have. Perhaps even a hard drive.

when you're at home. plugged in. your macbook would use the external devices and you'd have a lot more horsepower for your regular uses.
But easily unplugging your cable, and walkign away, a complete portable computer.

The new AIR's would be perfectly matched with such a system.

Yes, I always thought such a mother-ship unit would be great for portable devices, especially for video cards where even MacBook Pros have limitations due to space and heat issues.
 
Let's not forget that we hardly have any evidence that TB even works. Obviously, being Intel creation, it should work. I do not doubt it. Still, do we have any evidence that someone in the real World actually used TB? As we know TB cable is used for carrying two "signals": PCIe and DisplayPort.

Exactly, tech companies don't test the functionality of new products during research and development.

But, since there were no TBolt devices on the market, how could any company test TBolt during research and development?

The answer is obvious that no testing could have been done with production devices. Therefore, we're seeing delay after delay, firmware updates, and *still* few if any items actually shipping. The only "in stock" TBolt item at the Apple store is a $50 cable.

FireWire was and is far from a failure.

Agreed. FireWire 800 is great. I am looking forward to Thunderbolt!

Six max.




Except for the fact that your "TBolt peripherals" will really be "USB 3.0 peripherals connected throught a TBolt controller and a $50 cable to your system".

Wouldn't a couple of USB 3.0 ports on your computer make a lot more sense?

TBolt will be interesting for some niche controllers, but for 98.314159265358979323846264338327950288419716939937510% of the users native USB 3.0 would be a much better solution.




There's some serious voodoo in those active TBolt cables, that's for sure. Ya' gotta' pay the man.




Love it - mouse with two cables to fit in the daisy chain!




I don't believe that any TBolt devices have shipped to the general public.




Not really - TBolt is an external opaque transport to connect external PCIe devices.

There are no TBolt peripherals, only PCIe peripherals.

So, tell the Apple fans that TBolt doesn't exist, that it's nonsensical. (I agree with you here - that's the point that I've been trying to make.) I shudder at the ignorance whenever I see a serious comment about someone wanting a TBolt mouse.

He was obviously joking about the TB mouse. But everything else you said is wrong so you might as well get that wrong too.

Six isn't the daisy chain limit?

Ooops.

Cable to nowhere? :D
 

Please explain the "oops", if you can.

The other poster wasn't able to point out my errors either.


TBolt peripherals are any peripheral connected via TBolt.

We simply need to agree to disagree on this one.

Someday, when it actually ships, imagine that I plug a USB mouse into an Apple TBolt Display.

If I look at the device characteristics or the PCIe map - there's no "TBolt mouse" on my system.

It shows up as a "USB mouse".

If I connect a TBolt disk enclosure, I don't see any "TBolt disks" - I see SATA disks connected to a PCIe SATA controller (or virtual disk LUNs connected to a PCIe RAID controller).

When I say that there are no TBolt devices, I mean that a remote root user on the system might not be able to tell if the system has any devices connected via TBolt. To the system, they are all devices connected through PCIe controllers - like all or almost all of the other devices on the system.


I'm still confused ... what exactly is native TB to you? Your earlier example of two mDP is what the Thunderbolt display has. As for the rest, I thought Thunderbolt was simply a fancy, long-range PCIe connection that also carries video. So what does having a PCIe driver have to do with a device not being native Thunderbolt? What would be the advantage of being "native"? My questions are in earnest. I'll admit this is not an area I know much about and your discussion is somewhat difficult to follow ...

"Native" would mean that the device directly connects to the TBolt controller, not through a TBolt -> PCIe bridge -> PCIe controller -> device.

From the system viewpoint, TBolt doesn't exist.

It passes DisplayPort signals through untouched.

It allows PCIe controllers (either slot-based or embedded) that are outside the box to be used, and devices attached to those PCIe controllers to be seen. They are seen as PCIe devices, though, not as TBolt devices.

I can't wait for someone to actually receive a TBolt device and post the PCI mapping for the system.

USB3 is a different matter, its matched its year 1 numbers, do you think TB will grow by 260% this year... to match the 18% its done for year 2.

Growth is also not just defined by the number of machines with TB/USB3 its also the accessories. In 1 year there were hundreds if not thousands of USB3 adapters on eBay for various things such as hard drive, USB, ethernet adapters , memory keys etc. So far we have... a couple? TB devices - very high end disk arrays.

IMO its the accessories that decide the sucess.
Year 1 for USB3 was 2008. First usb3 device shipped in 2010. :scratch: Just over a year apparently. Like they say, the more things change the more they stay the same. Facts, people, facts; an important part of reality.

Addendum: Really you were right; I only needed to go back to 2008 to demonstrate TBolt is reasonable and could still succeed.

I've read through a lot of these threads on MR since TB was announced, and I could probably find 1 in 10 forum members that conceptually understand TB.

TB is fast now and will be faster still in the future, but it isn't just about data transfer. It's about latency, in the neighborhood of 8 ns, synchronization of data streams, and flexible protocols. These are not strengths of USB 3.0.

Apple, Asus, Acer, and Sony see a future of mobile devices morphing into full fledged workstations, and if that is what is desired, TB has the underlying technology that USB 3.0 does not.

Complementary is how Intel would describe TB an USB 3.0 and I would agree with that.

Wow, it took me a few reads to understand this, but once I envisioned Yoda saying this, it made sense. Thanks for the explanation.

Good. So long USB, you were great. Tb will go thru 2 or 3 revisions before adding optical and will only get better... If something else doesn't replace it first.

Easy, you make some devices to test TBolt and the devices themselves prior to being released.

You have already replied to that post. I have already replied to your initial reply to that post. See below:

By that I mean there are not any current or announced native TBolt peripherals, and probably never will be.

In my view, a "TBolt peripheral" has two TBolt (mDP) connections and can be inserted into a TBolt daisy chain.

So, do TBolt peripherals exist or not given that TBolt is a native PCIe external interface?

There are several examples that fit your parameters of a TBolt peripheral, including the Apple Thunderbolt Display.

So, as occurred in other threads, you are being prone to negating your own arguments.

A "USB 3.0 disk connected to a USB 3.0 hub connected to a USB 3.0 PCIe controller connected to a TBolt->PCIe bridge" is not a TBolt device in my parlance. It's a USB 3.0 disk.

Obviously, a TBolt peripheral would require a TBolt port to be deemed a TBolt peripheral.

"Native" would mean that the device directly connects to the TBolt controller, not through a TBolt -> PCIe bridge -> PCIe controller -> device.

Intel doesn't seem to agree with you in relation to your belief that TBolt is not a native external interface for PCIe. See below:

Six isn't the daisy chain limit?

Nope.

But, I said in the next sentence "The answer is obvious that no testing could have been done with production devices."

Any person with any QA sense would know that testing with a couple of hand-built prototypes is not a substitute for testing with multiple off-the-shelf devices. The recent spate of firmware upgrades, and the mysterious delays in shipping TBolt monitors and devices are proof of that.

When I read your slide, I see "native PCIe", not "native TBolt". Intel agrees with me.



Then please describe the TBolt daisy-chain topology if I'm wrong about saying 6 external TBolt controllers in a daisy-chain.

This sentence doesn't seem very ambiguous to me: "Thunderbolt I/O technology allows you to daisy-chain up to six Thunderbolt peripherals"…

That said, AidenShaw: I can't believe most of this drivel you're saying here. You seriously don't think that the manufacturers of the upcoming production devices haven't or aren't going to test it themselves? Give me a break.

That's why you introduce computers with ports that no devices exist for: so people can make devices that work with them.

If a hard drive is connected via Firewire 800, it's a Firewire hard drive. It might also have a USB 2.0 port on it, or an eSATA port on it, as mine do, so it's all of the above. If a drive can be connected to a Thunderbolt-equipped computer via a Thunderbolt cable, it's a Thunderbolt hard drive. It doesn't matter what protocol it uses. The interface is what matters.

http://www.lacie.com/products/product.htm?id=10549

Interface: 2 x Thunderbolt 10Gbits

What is the point of insisting otherwise? At best, you're just splitting hairs. At worst… I can't even type it, because I'd get a warning from a mod.

It's Apple that shipped computers without testing TBolt with production devices.

Usually there is a coordination so that there are at least a few "launch partners" with devices ready. Instead, it's mid-September and for all intensive porpoises there are still no TBolt devices available for the computers that Apple starting shipping in February. We are getting a lot of firmware updates, though.


If a drive can be connected to a Thunderbolt-equipped computer via a Thunderbolt cable, it's a Thunderbolt hard drive. It doesn't matter what protocol it uses. The interface is what matters.

If you want to connect a 3 TB drive to your Apple TBolt display, do you buy a USB drive, a 1394 drive, or a TBolt drive?

Yes, the interface matters.

As I said, I'm looking forward to seeing the PCI maps for these devices - I doubt that the system will see any "Thunderbolt" devices.

I feel a disturbance in the Force.
It's like a million engineers screamed out and started beating their heads against the wall at the same time.

I honestly can't tell if you're agreeing with me, or making fun of me! ;)

The engineers say "We can't test it", and the turtlenecked pointy-haired managers say "Ship it!".

By the same logic there can't be devices to test with without some one releasing a device with a host controller. It quickly becomes a chicken and egg thing. This equally applies to USB3.0 or anything new that requires a group of things. Sure USB3.0 devices could test they are backwards compatible with a USB2.0 host or the reverse but in either case one of them has to ship (or at least be shippable) for there to be production equipment to test USB3.0 on USB3.0.

Someone has taken a punt on at least one side of cable or nothing happens.
Apples price point model allows them to use savings as tech gets older to take those sorts of punts. Yet they still have to laid off the risk, and to be really selective about which to back to give them advantage in their markets.

It's not like couldn't test it at all. They could test many parts of the system, and model others to come up with a risk cost. If that is in the budget then it ships. It would make sense then it always has to be the host that ships first as it is a much smaller part of their value equation.

It's not like Apple just took a blind punt, they did have the PA Semi guys after all.
 
This is great. The more momentum the better. Thunderbolt has a lot of potential... so hopefully we'll be able to use that potential! Now Apple just has to add USB 3 as well... I think the 2 technologies can coexist very well together...

It's unusual to ship systems for 7 months with untested silicon.

Earlier I called these "teething pains" - worrisome, but most likely will be fixed over time.

TBolt won't be a "train wreck" unless Apple has to replace the early motherboards with revised silicon.
 
Wast just looking at the dock for the sony z series, the one which has a external blu-ray burner and a dedicated graphics card in it.

Are there any plans for something similar for mac products? I personally think it's a simple yet amazing idea.
 
Six isn't the daisy chain limit?

Your statement shown above doesn't define any limit to only TBolt devices.

A daisy chain allows 6 TBolt devices and 1 DP device for a total of 7 devices.

Then please describe the TBolt daisy-chain topology if I'm wrong about saying 6 external TBolt controllers in a daisy-chain.

Interesting, you include the limit of only TBolt devices only after being shown that slide which reveals your error.

But, I said in the next sentence "The answer is obvious that no testing could have been done with production devices.

This doesn't make a difference given that production devices are built to specification of the standard.

Any issues of production devices not functioning properly are due to an error on the part of the device manufacturer not building to the specifications of the standard. This can occur at any time after a standard is released to the public and is just as likely to occur in relation to any standard.

When I read your slide, I see "native PCIe", not "native TBolt". Intel agrees with me.

TBolt is the native external interface for PCIe.
 
I think it is great we are beginning see a wider adaptation of Thunderbolt. I really hope for this port to survive and thrive.

All the USB 3.0 vs Thunderbolt discussion is a bit pointless. These ports are vastly different and should not be compared.

The beauty of Thunderbolt is its ability to work as a docking port. In the era of mobile devices like iPad or MacBook Air, it is a very important aspect. There are a lot of industries out there that require huge processing power (be it GPU, CPU or even sound cards) that is just not present in these mobile devices, forcing people to use 'pro' machines at work, mobile machines for commuting and gaming machines for entertainment. Thunderbolt is the first development I know of that promises to change it. I would love to be able to use a light MacBook Air when I commute, then plug it via Thunderbolt into an OpenCL compatible graphics card at work, daisy chained to a RAID matrix, allowing me to do heavy duty processing work required for my job, and then when I get back home plug it into a good dedicated graphics card daisy chained to a large LCD for gaming purposes.
