Dell's unassuming Latitude 5480 could be the sleeper eGPU laptop you've been waiting for

I'm the one who wrote this reddit post

That, again, does not mean it is true. ...

So, before buying anything, I would advise to wait for actual benchmarks and reviews of the laptops.

Thanks for digging that list from Dell uPanda. I looked but wasn't able to find a twitter post from them, so I assume this was a DM. I am well aware how difficult they are to work with ...and how inaccurate Dell reps can be. Hopefully, we'll find the information proves true. You certainly posed a very useful question to them.

My own difficulties with Dell / Alienware have now connected me with a special team trying to resolve terrible factory issues many of us encountered last December. I've spent around 20 hours and am still helping them clear up misinformation. But at least, I'm working with better trained sales reps. Just now, I've been told my rep has found some "new source" for technical details other than pre-sales. Hopefully it will prove more fruitful and might answer some of these mysteries..

there is no ips so its a shortcoming but the price is pretty suitable for a egpu laptop,and i think it well be better if it get a little bit thiner

Hello,
AquaeAtrae tells us, in every thread about the design flaw with xps13 9350 &  atest 9360, 9550 & latest 9560, that x2 lane TB3 is equal to x4 lane TB2 and that does not affect gaming at all !
Remember first that TB3 is running from 2015, and 9560 is 2017 a fresh selling, 9360 same few months before.
So with that XPS FAKE TB3, there is NO WAY to run eGPU greater than GTX750i (2014) without 20% drop at leat drop on any external FHD, and that is 50% drop at least when using internal FHD screen (more of course on 4K display or QHD+ internal screen...).
DeLL retired not workingTB15, and 4K display with TB16 is still buggy and only 30fps capable.
Finally, it's the same with rapid SSD (9560pro & so) that can't deliver all their juice at 12mbps (2x8Gpbs minus overhead) and needs for sure TB3 REAL implemantation.
Nice job DeLL, nice companion AquaeAtrae ....

Hi,
to know what you are buying, this is the Feb,27 official PCIe lanes by model' note DeLL posted on "Knowlege base" to stop any further claims : http://www.dell.com/support/article/en/en/frdhs1/QNA44089/thunderbolt-3-data-transfer-speeds-up-to-40gbps?lang=EN
good reading.

Here's the first actual implementation details of the XPS 15 along with benchmarks.

After testing Rise of the Tomb Raider fully maxed out...
"For my use case (4k external) this puts me 5-7 FPS behind what reviewers are getting online..., which is acceptable losses for me." - jackeyjoe

Use of the internal display is also tested with the x2 bi-directional PCIe lanes.

And for anyone still unfamiliar with the range of Intel's Thunderbolt 3 specifications of what they actually mean...

"The Basics
A Thunderbolt 3 port requires that each connector be provided
with at least:
• The equivalent of two lanes of PCI Express Gen 3 data
• One full DisplayPort 1.2a (four-lane) interface"
