I wonder if it would be possible to use 2 Thunderbolt 1 ports for this so you could get the speed of Thunderbolt 2 which would allow more bandwidth?

Have fun! I can't even run Mail, Safari, iTunes and do some iPhoto work in the summer month at the same time on my 2010 Air. After ten minutes or so the back side is hot as hell and the fans are going crazy.

It's supposed to get hot. The Air's enclosure is just like a giant heatsink, same for the iMac, Mac mini, MacBook Pro etc.

Kick starter anyone?

Great idea. I'd happily contribute to that!

I left the Apple platform about 10 years ago because a major hobby is gaming. And I mean "proper" games. All my mates were building their own PC rigs, customising as required and we were all into tech and components anyway so it was a great tech outlet.

A year ago I switched back to the Mac but still use the PC for gaming.

Sad to see that not much has changed on the Mac gaming front.

Especially sad as it's Apple. Yeah, yeah I know you can probably get *some* of the major titles like Elite and Half Life 1 but the fact is I would'nt consider the Mac a gaming platform. And I wish it was because then I wouldn't have to switch machines when I want a decent game to play.

Even if I bootup in Paralells or BootCamp, we still have the issue of needing a TB connected GPU in a sexy exnclosure.

So yeah, I'd put my money where my mouth is and fcrowd fund a TB enclosure for something like this small GPU

This goes against the whole point of a MacBook Air.

Someone who buys an MBA in the first place is presumably wanting portable productivity. They are probably not looking to do this type of high-end gaming on it.

EDIT: I agree wholeheartedly with all the posters the saying that this would be an at-home solution. I admit to overlooking that part. This I would not mind even for my MBP's crummy Radeon 6490M.

But seeing as I play older games and that my MacBook Pro already has a dGPU which handles them ok, I guess I just didn't see the justification of cost for something like this.

I speak as a MacBook Pro owner so I'm not going to make any presumptions of how MBA owners would feel about this. If this seems right for you, then by all means.

I'd love it if I could attach an external video card to my rMBP. I have this big beautiful 1800p screen, but I can't run any but the most basic games at native resolution. Could also be a good opportunity to have adaptors for more external monitors, rather than the paltry three that the rMBP offers.
 
Apple could make a polished solution, something like Sony did with the Vaio Z.

Yup. They could put a high-performance GPU inside the Thunderbolt display.

QUESTION

Can anyone explain to me why Intel is apparently preventing third parties from producing Thunderbolt-to-PCI-Express adapters?

How would it harm their business (or the adoption of Thunderbolt) if these existed?

For extra credit, please provide a car analogy.
 
- Uses a somewhat dusty "high end" card
- Calls playing on a tiny 11" screen notebook "gaming"
- Plays Borderlands 2 to demonstrate graphics power.

Yeah.

Not clear enough?

Possibly very stupid question ahead, but how is that setup different to something like this :

Whilst that would be no use what so ever for me, it is fantastic work. I'd buy that chap a beer.

But then it wouldn't be upgradeable along Apples current trend.

Funnily enough, I can live with my CPU being a few generations old and not have any issues on my line of work but a non upgradeable GPU would be a dud.

Keep the GPU in an external enclosure and then you can use it on your macbooks, iMacs, etc etc
 
so, correct me if im wrong, but this kinda thing could also be used on the audio side of things?

Yep, you can use the new Sonnet Echo Express III-D/R with Avid Pro Tools. It supports up to three Pro Tools|HDX cards:

http://www.sonnettech.com/product/echoexpressiii.html

It's quite expensive, but it has Thunderbolt 2 and is upgradeable to future versions of Thunderbolt.

Or, if you're okay with previous-gen Pro Tools|HD Native, Avid makes its own Thunderbolt interface:

http://www.avid.com/US/products/Pro-Tools-HD-Native
 
This just might the future of Apple computing: minimal components inside the case, plenty of Thunderbolt expandability. Compute modules, GPU modules, storage modules, and maybe even 3rd party plastic disc-burning modules.

Seems like what they are doing with the Mac Pro. Not sure if notebooks will also see the modular approach.
 
It's not about the money or the gaming performance,
it's about sending a message. :)

I own the early 2011 13" MBP with thunderbolt lol never used it,
why?
cause there is no single thunderbolt device for a causual person like me.
dont need a superfast big external hdd, cause i got a nas so all network devices can use the files. for sharing files i got an usb 3.0 64gb stick.
first time i heard of the tb->pcie box i was amazed and couldnt wait to buy one, but nothing came and i forgot about it. then silverstone presented their box, i was still amazed but thought *its about time*... and damn nothing came.

in my opinion, thunderbolt could be the best interface, but if there is a lack of products and no range of things to buy, the interface will go down...
 
Thunderbolt 1 is 10Gb/s
PCIe x4 v2.0 is 16Gb/s
Thunderbolt 2 is 20Gb/s
PCIe x8 v2.0 is 32Gb/s
PCIe x16 v2.0 is 64Gb/s
PCIe x8 v3.0 is 64Gb/s
PCIe x16 v3.0 is 128Gb/s

The more you know!

I guess it won't really be feasible until thunderbolt 13.0 by which time we'll be at PCIe x16 v8.0, so it's moot anyways =p

Take those numbers with a grain of salt.

They're the theoretical numbers, and the bus is never actually saturated with that much data. From what I've read on Notebook Review you're only seeing a 15% loss in real-world performance against PCI-E x8 v2.0?

they're not.
they're just not giving it away for free.

want to make thunderbolt, you pay the License fees for the patents.

(sound familiar?)

Image

The Vaio Z was thinner and half a pound lighter than an MacBook Air, but had full voltage processors (up to quad core i7) like a Pro. The external case isn't just for the Blu-Ray reader/writer – it also housed a AMD graphics card.

Wow! Did not know this existed. This would have been the ideal set-up for me. Macbook Air just for on-the-go, and some sort of Power Dock at home that I can just plug and play for games/movie editing and such.
 
Sorry for insisting, but what about products like this?

http://www.magma.com/expressbox-1t

I'm not sure I understand what's different here...

Magma's boxes are not rated to handle GPU's.

The 1t you listed only supports up to 65w power draw in a 1/2 height PCI-E card.

Effectively limiting the power of any GPU you would install to well, probably on par with the internal GPU that the macbook airs already have.

And this box alone (no cards with it), starts at $480. (cable is $60 extra)

at $979, you can get 3 "half height" cards

I also have read somewhere on their site in the past, that it is not for use with GPU's
 
Fair enough, so if I understand you correctly the only limiting factor here is power supply (?). And well yeah, price.

Is it really crazy to imagine that the next generation of such products will support higher power draws?
 
i still dont understand why no firm is evolving something like this... like GSUS etc.

im sure many people would buy this

The concept of notebook and docking station with dedicated GPU is quite old. In fact IBM's Thinkpads had this in the past. As with all external solutions they're expensive and technically limited (bandwidth). Thunderbolt doesn't change this boundary condition.

Commercially this never took off. Only few people really need high end GPUs:
* engineering/construction/CAD (very limited market, mainly using PCs)
* gamers (wide market, but very price sensitive)

There are just not enough people that would be willing to spend a huge amount of money on this (expect more than USD 1.000 for such a solution).

The guy who did it is cool, nonetheless !

Stupidly expensive for gaming purposes. It's cheaper to just buy a desktop system. Hence why there is a lot of interest in a US$250 Silverstone T004 capable of hosting dual-width full-length cards complete with a 450W PSU. From article (second post):

Best upcoming option: US$250 Silverstone T004 450W native 10Gbps Thunderbolt enclosure

The affordable gamechanger may come if Silverstone T004 is released in the coming month or two. US$250 for a 450W double-width, full length and width 10Gbps Thunderbolt eGPU enclosure. No messy wiring, well priced and looks great. Awesome. Will only be available for purchase if they pass Intel certification. Am curious if Intel will continue to be a fun-wrecker or finally concede.
