Dell Latitude 7xxx series TB3 support
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).
