Hello,

I am looking for a way to connect my Gigabyte NVIDIA AORUS GTX 1080 (Thunderbolt 3) to my Latitude Laptop 7490 which only has USB-C and no Thunderbolt.

Is there a hack to make this work? I am thinking of a device that would convert USB-C protocol to Thunderbolt 3.

Thanks!

@sefable No, you need Thunderbolt or something on your motherboard that has PCIe (an M.2 slot or mPCIe slot).

Thanks! 

 

If I have an M.2 slot or mPCIe slot, how do you suggest I connect my GTX?

With one of the solutions or similar listed in the buyer's guide and/or builds.

M.2 socket 3 (NVMe, AHCI) would be best. Other M.2 (socket 2) or mPCIe or ExpressCard are the same but check your specs.

Thanks!

I'm not sure I follow correctly. My enclosure only has Thunderbolt 3, so how would a M.2 socket 3 allow me to connect to Thunderbolt? Would you give me just one example? I can't seem to find what I need on the links you gave.

Unfortunately I don't think it will be possible. The M.2 slot on your machine seems to be SATA only. It looks like there might be a mPCIe for the wireless card, but then you'd have to lose WiFi and Bluetooth, and get one of these to get a full sized PCIe slot out of your laptop. You'd be limited to the single lane link, and might have to cut some holes in your case to make it work, all in all, not a worthwhile project imho, unless your motivation is curiosity, in which case it's all cool!

Thanks for your help!

So do you confirm there is no way to "add" thunderbolt 3 to a machine? I'm trying to keep the GTX in its box with Thunderbox 3.

I find it difficult to believe there is no solution, either through USB-C or any other bus, to add thunderbolt support to a machine.

Is it because Thunderbolt 3 works at 40Gbps and USB-C works at 10 Gbps that we can't add Thunderbolt 3 through USB-C?

First you would need a PCIe slot using an mPCIe adapter probably (USB-C does not have PCIe). Then you could connect a Thunderbolt 3 add-in card to that, like the GC-TITAN RIDGE. Then you could connect the Thunderbolt 3 eGPU to the GC-TITAN RIDGE. But the GC-TITAN RIDGE might not enable PCIe tunneling over Thunderbolt and/or the eGPU might not work. But it might. I mean, it worked with the Mac Pro 2010 which has no support for Thunderbolt 3 built-in.  https://egpu.io/forums/builds/2010-mac-pro-nvidia-rtx-2070-radeon-pro-wx-910016gbps-tb3-mantiz-venus-win10-1803-itsage/

But, if you're going to add a PCIe slot like that, then you should just connect the GPU directly to that and skip the Thunderbolt 3 add-in card and eGPU.
