Can the new Hades Canyon's CPU bottleneck a 1080 Ti via thunderbolt 3?

The new hades canyon uses this processor:

Intel Core i7-8705G

 

Kaby Lake, 4C/8T

 

3.1GHz (up to 4.1GHz), 14nm+, 8MB L2

 

65W Package TDP

I am thinking of connecting an eGPU (1080 Ti) to its thunderbolt 3 and was wondering if I can get the full potential out of this graphics card.

Hello backslash,

 

 

Thank you for contacting us regarding the compatibility questions that you have about the upcoming Hades Canyon NUC series; it will be more than pleasure to assist you with your inquiry.

 

In this case as you may know the upcoming NUCs will be:

 

- Intel® NUC Kit NUC8i7HNK

 

- Intel® NUC Kit NUC8i7HVK

 

Here you will find all the information and technical specs about it:

 

https://ark.intel.com/products/codename/126373/HADES-CANYON?q=Hades%20Canyon https://ark.intel.com/products/codename/126373/HADES-CANYON?q=Hades%20Canyon

 

The new feature for the upcoming series will be Radeon™ RX Vega M GL graphics.

 

Essentially a 1080 Ti will be compatible (electronically and physically) through Thunderbolt 3 with our unit, however we do no guarantee the best performance/compatibility or full potential, your results may vary, due to the fact that the unit is no intended to work with this type of cards (GTX 1080 Ti).

 

As soon the product is released we should have a list of compatible/tested peripherals such as the ones listed on https://ark.intel.com https://ark.intel.com for another older NUC models.

 

Our best recommendation is to wait until the product is fully released in order to determine the compatibility of the product with this kind of peripherals.

 

 

I hope this helps.

 

Best Regards,

 

Diego S.

Thunderbolt 3 is four lane PCIe 3 while the 1080Ti supports up to sixteen lanes. First glance means limit to 25% of capacity. So no, technically you can not get full potential from a Thunderbolt connection. Real world (even games) shows loss of only a couple percent. https://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/21.html GeForce GTX 980 PCI-Express Scaling | TechPowerUp

Thank you for your response. Could you tell me where exactly I need to look for the compatibility list?

Thanks for the useful link. What I'm concerned now is that the CPU might bottleneck the connected GPU compared to a desktop CPU like the i7 8700.

It doesn't list anything related to eGPUs.

Why would it? The unit is designed to present you with a much, much better video solution so you can avoid having to resort to things like eGPUs....

Just saying,

Why would it? because it's a compatibility check page.

The integrated GPU is good for 1080p gaming mostly.

Hello backslash

 

 

Thank you for your response.

 

 

On the tested peripherals list there is no eGPUs due to the Hades canyon comes with a video card for high-end graphics.
