PCIe Lanes on Thunderbolt 3 Port.

[Kalavere]

Hello folks, 

I'm looking to use an eGPU with my Spectre, I am curious to know before spending £400+ on an enclosure and more again on a GPU and suitable active Thunderbolt 3 lead, whether my X360 -15 Ch004na had two or four Lanes on the Thunderbolt 3 port. 

I've looked on the official web page and had a Google, I've not come up with a definitive answer from a trustworthy source, can anyone shed any light for me?

Kind regards.

Its specs:

which clearly says it has

     2 Thunderbolt™ 3 (Data Transfer up to 40 Gb/s, Power Delivery, DP1.2, HP Sleep and Charge) ports

That means those ports are standard Thunderbolt™ 3 ports which are suitable for eGPU such as

Yes, I am well aware of the potential thoughput of the standard, Thunderbolt 3, being 40Gb/s.

My question as stated in my first post is; how many PCIe lanes does the motherboard have avaliable for an eGPU enclosure?

Can you please show me documentation of that?

Have you checked https://egpu.io/build-guides/   for your model and see peoples' benchmarks?

No sir, I wasn't aware of that site. I'm only aufait with desktops.

Thanks for the advice and the link, much appreciated.
