[TS] MSI demos Thunderbolt-based external GPU solution. [CES2012] - Page 3

post #21 of 45
How do people expect a 10 Gb/s, i.e., 1.25 GB/s interface to even remotely not bottleneck a capable graphics card?

To clarify, a four-lane PCI Express connection provides 2 GB/s of bandwidth - and who would ever recommend running a graphics card with four lanes?

Whoops. Seems like it's not that much of a bottleneck in most cases. Not sure how much worse 1.25 GB/s vs. 2 GB/s would be, though.

More laptops need thunderbolt for this to really take off. IIRC sony has the only non Mac based Thunderbolt connection.

I'd be more than happy using it with my MBP tho.

So far I've heard a few laptop manufactures, believe Asus and Acer (or MSI, not 100% sure on those) are planning on adding Thunderbolt using the miniDisplayPort connection released around the time of Ivy Bridge. Sony's Thunderbolt, if they haven't modified it already, is suppose to be a modified USB 3.0 port, but that's not possible to do as the USB Implementers Forum denied Intel and Apple to use it for Thunderbolt as "USB was not open to modification in this way" as they said. Knowing Sony, it's probably some proprietary connector.

It can support up to a 150W card, so that can be a pretty decent card.

I'm hoping that when I do my next computer hardware upgrade with Haswell, Thunderbolt will be included on many motherboards, so by that time, prices should start leveling out. I just want a motherboard that has only a couple ports, for example 2 Thunderbolts, 2 or 4 USB 3.0 and audio with everything else in a desktop hub, FireWire 800, eSATA, Gigabit ethernet, 4 more USB 3.0 ports, and of course another Thunderbolt port.

I think we can all agree that we will settle for an external GPU that will house any GPU, but has to come with an external power brick.

Man, I would love this for a 7950 or a GTX760 for an ultrabook. I'll ditch my gaming notebook right away biggrin.gif

Looks like Lenovo, MSI, and Acer will be releasing laptops with TB soon, with more to come from Asus, and others.

MSI is releasing a Z77 Ivy Bridge board with Thunderbolt along with Intel's boards. Also heard Asus, ASrock, and Gigabyte will also be releasing boards with TB as well.

I think by the year's end, we should have a slew of TB boards, laptops and devices, meaning prices will be going down as well.

The big problem here is how would you power the GPU?
An external PSU? Thats even more to lug around. You can't transmit enough power via thunderbolt to actually power a decent GPU
