DELL Inspirion 7391 with i7-10510U - TB3?
Hello guys and girls,
First: thanks for such a precious gem, namely this website and forum.
I just bought the Dell Inspirion 7391-based laptop / convertible with a i7-10510U, 16gb DDR3-RAM, 512GB NVMe-SSD.
I know I should have asked beforehand, but it was a nice deal and I'd really like this notebook for daily use.
Now since I intend to replace my desktop, I would like to know if I can connect an external GPU-case via Thunderbolt 3. The XPS13 models claim they have a x4 connection while this model didn't, but I hope so.
I am rarely playing games at all, but when I do, I want a good performance on 1080p or 2160p. I play RocketLeague for the most part.
Will this laptop (I just ordered it, so I could return it within 14 days if it happens to not satisfy my needs) be able to run a TB3-eGPU-box with say a 1080GTX?
Does anyone by any chance know anything about it?
Thanks for your help and time in advance!
@igor_dasunddas It has only one Thunderbolt 3 port so x4 PCIe connection is not a given. In late 2019, I would find it very silly for any manufacturers to implement Thunderbolt 3 connectivity at x2 PCIe however. You can download and run HWiNFO64 then expand the PCI Express Root Ports to see more details. This is a screen capture on MSI Prestige 15 which has i7-10510U CPU. You can see under PCI Express Root Port #9, there's a PCI Express Bus #3 with an x4 connection going to Intel JHL7540 Thunderbolt 3 controller.
I just got my device today and I tried my best, but I am not entirely sure, if this device has full x4 TB3 support.
According to a Service and Setup Manual I found on Dell, it apparently is expected to support full speed. The attached screenshot suggests so, too.
Edit: just figured I could start the "Intel Thunderbolt (TM) Control Center" and in the "Info" menu it says the following:
Application version: 220.127.116.11
Thunderbolt(TM) Controller 1
Thunderbolt(TM) Generation: Thunderbolt 3 (15E8)
Port count: 1
Security level: Kernel-DMA-Protection (SL1)
NVM Firmware version: 41.0
External GPU support: yes
So I guess it does support Thunderbolt 3 with 4 lanes or at least it seems to say so.
@igor_dasunddas That is most likely a x4 PCIe 3.0 Thunderbolt 3 connection. The only unknown is the particular TB3 controller inside the laptop. That information would only show up when you have a Thunderbolt 3 connected.
Alright. I will probably try to get my hands on a box and see if a 980gtx works with it.
I wiall post a build once I accomplished it. Thank you very much for your time and help!
I don't see any Thunderbolt controllers in the pictures. Connect at least a USB device (even a mouse or keyboard will do).
15e8 is the JHL7540 Thunderbolt 3 NHI [Titan Ridge 2C 2018] according to the pci database but I think 2C refers to the JHL7340.
I will connect my phone later today and make another screenshot. I also ordered a 1080 gaming box from gigabyte, scheduled to arrive till Saturday.
Edit: it seems I don't have a proper USB-C-to-USB-C-cord.... waiting for my box to arrive...
I've just gotten my Gigabyte Aorus 1080GTX Gaming Box today and attached it to my Dell Inspiron 7391 (7000 2-in-1) laptop and here's hopefully the right screenshot:
If you got any comments on this (whether positive or negative), please feel free to let me know.
Edit: RocketLeague works, but it seems I had to update the drivers (or perhaps I didn't have to...). In 1980x1080 internal display on max settings absolutely flawless. I'll try to run some benchmark / write a build once I also tested out the external monitor (4k@60hz).
@igor_dasunddas You're good to go! As can be seen under the PCI Express Root Port #5, there's a PCI Express x4 Bus going to the Alpine Ridge Thunderbolt 3 controller which hosts the GTX 1080 eGPU. Enjoy your setup!
