I'm looking to buy a new laptop and I want to make sure that I can connect an eGPU to whichever hardware I'm buying.

I'm eyeing the new Dell Latitude 7300 or 7400 mostly because I can get a really good deal on them through the university. However, I am doubting if these models support an eGPU at all. The standard models (not the 2-in-1 type things) only have one TB3 port. According to the Dell website they have full TB3 support but I find no resources to confirm that.

The closest one I find is this build from about a year ago. It's obviously not the exact same model.

Did anyone already try these models? Do I even need to worry about it and just bite the bullet?

The web page at https://www.dell.com/support/article/ca/en/cadhs1/qna44089/thunderbolt-3-40gbps-data-transfer-rate?lang=en does not say the TB3 port of the 7300 or 7400 has 2 lanes, so I guess you can expect 4 lanes (has better performance than 2 lanes but either will work).

You only need one TB3 port to connect an eGPU. I don't know any reason why an eGPU wouldn't work (except the usual problems discussed in PC laptop eGPU builds that you've probably already looked at).

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

Dell confirmed to me that the latitude 7x00 laptops do have full thunderbolt 3 support.

However, I ended up ordering a Thinkpad Carbon X1 gen 7 through a good deal as well.
