Using Active USB-C 3.1 Gen 2 Cable on Thunderbolt 3 eGPU

I happened to purchased few generic USB 3.1 Gen 2 Type-C active cables (1 meter) (it has chip and shielding in connectors ), and it surprised me when I connected it with the Akitio Node and found it works.

Speed test suggests it is slower than the default cable from akitio. (Akitio: 2.487/2.529;  Generic: 1.704/1.728)

I just want to share this information.

Interesting find. Can you PM me the link to the cable?

I've confirmed with engineers that USB 3.1 Gen2 Type-C cables will work if it has the e-Mark. However, you will only get up to 20 GBps. We don't recommend using these cables.

Thanks a lot for confirming!

The 20 Gbps does make sense, as I see an obvious drop in speed.

Just out of curiosity, Is there a software tool for examining thunderbolt 3 link speed (i.e. how to tell 20Gbps from 40Gbps without benchmark) ?

The page I brought it from was kinda sketchy, and I am not comfortable promoting it here. (The cable came in plastic film without retail package, and it has no branding or marked certification at all. Plus you will most likely need google translate and freight forwarding)

Since DanKnight has confirmed that it will work with any cable with E-Mark, I would suggest finding one from a confrontable retailer.

I'm not aware of any public tools.

Again, I highly recommend to stay away from these generic USB 3.1 Type-C cables with the Node and even other devices. It could result in serious damage to your device and even kill your computer.

 

e-Marked cables are safer, but research if it's actually e-Mark'd before buying. The e-Mark is there to let the computer know if it's a legit certified cable. There were issues in the past before e-Marks where generic cables were poorly made and completely destroyed the computer when connected. (sort of like a USB killer)

@visviva, Did you use on a mac device or windows device. I really want o know because I wanted a egpu,  but was declined since I realized I have a 3.1Usb-c instead of thunderbolt. Now that I know it ACTUALLY WORKS I can buy the cable and the laptop I have has Usb-c 3.1

@miah_adib, you need Thunderbolt controller in your laptop to use eGPU. The cable can be USB-C (will be limited to 20 Gbps when connecting to Thunderbolt) or Thunderbolt.

@miah_adib, use what with eGPU? Avoid pronouns.

@joevt, I meant using the e-marked USB-C 3.1 cable can I use the egpu to game meaning can I use the graphics card on the egpu to game. Even with the 20 gbs bandwidth can I use a external monitor? I would like to connect using the usb-c cable from egpu to laptop and displayport from egpu to monitor. Will this work?

@miah_adib, you have not described your hardware. What is the model of your laptop? Does it have Thunderbolt? If it does not have Thunderbolt, then you cannot use a Thunderbolt eGPU. If your laptop supports Thunderbolt then a USB-C cable might work to connect and use a Thunderbolt device such as an eGPU, but it will probably only allow 20 Gbps. It should work, but if you have money to buy an eGPU, then you should get a Thunderbolt cable (eGPUs usually come with a Thunderbolt cable so it is usually not a problem).

@joevt, I have a USB-C 3.1 imput but mentioned in this topic the e-marked Usb-c 3.1 cable can be used for the egpu. I plan to use USB-C 3.1 to egpu with E-Marked USB-C cable and DisplayPort from egpu to 144hz monitor. Is this enough to have the EGPU work meaning I can use the Graphics card on my display.

My laptop:

Hp Envy X360

My monitor: Sceptre 144hz Gaming Monitor

EGPU I want to use: 

Sonnet Egfx

@miah_adib, No. USB is not Thunderbolt.

I looked at the Hp Envy 360 page. There are 11 of them. Which one do you have? None of them have Thunderbolt.

If you want an eGPU then you need to connect it with mPCIe or NVMe (whatever is available in the laptop).
