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!

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.
** 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

Hi there, I want to buy the yoga 730, my only concern is that there is a 3-4 wk wait for the 8565u model. Is it really 4 lane PCIe, the whisky lake? I hear that the software you used here is unreliable for measuring PCIe lanes. Could you please run this test with hwinfo64? I would really appreciate it if you could run it soon since I want to buy ASAP, any help would be greatly appreciated!!

HWiNFO confirms that it is x2, I am running the 8550U, so it is possible that the 8565u model is different, but I would doubt it.
Don't get too concerned with the processor, power distribution is so poor that when the internal GPU is in use, the processor gets throttled down to ~1Ghz on all cores.

I ask about the thunderbolt 3 because most likely I will run an external GPU with my yoga 730. So the number of lanes is important to me. That's why I ask what the 8565u shows on HWinfo for 8565u
