PCIe Lanes for Thunderbolt 3 port on Yoga 730 15"

Does anyone know how many PCIexpresslanes are allocated to the thunderbolt 3 port on the Yoga 730 15". 

 

I have gotten in touch with lenovo technical support, but they had no idea. I did see where the 720 is thought to have 2 lanes, but I am not sure if that is the same on the 730.

 

Thanks for any info!

Hi Tilden,

 

Welcome to the Community Forums.

 

It appears to have 2 lanes as showing the schematics for the 15 inch unlike the 13:

I hope this helps answer your query.

 

Regards

 

** edit remarks : differenciate with 4 lanes in the 13 inch Yoga 730

The egpu connected to my 730 for the benchmark image above is the HP Omen accelerator, its decent for the price. I also ordered a Razer Core X which I can not recommend enough. The Hp Omen has USB slots at the back, but when you plug a peripheral in you notice a decrease in FPS so I normally plug directly into the laptop or a multi-usb adapter. The core X has a 600w PSU which is powerful enough for any card available currently and costs only $299

Thanks for posting proof. Does the throughput of the bus interface goes up when there is gpu load?
