System specs (model inc screen size, CPU, iGPU, dGPU, operating system which eGPU is being used)

Dell G5 SE 5055

CPU: Ryzen 4800H

iGPU: RX Vega 7

dGPU: RX 5600M

eGPU: RX 5700 XT

Windows 10

 

eGPU hardware (eGPU enclosure, video card, any third-party TB3 cable , any custom mods)

Used a 500W power supply and PCE164P-N06 for proof of concept eGPU on Zen 3 Ryzen mobile chipsets

 

Installation steps (what did you do to get it all going?)

Dell G5 SE 5055 has an extra empty M.2 slot, presumably for a second NVMe drive but it works just fine for eGPU with no extra configuration.

The Radeon Adrenalin Software recognizes the extra eGPU in addition to both the iGPU and dGPU in the software after a reinstall, however I had trouble getting it to recognize any displays connected to the eGPU until I disabled the dGPU and restarted the computer. After restart however the eGPU worked perfectly fine.

 

Benchmarks (Include a CUDA-Z or AIDA64 bandwidth pic. Optional: Valley, 3dmark, noting if it's on internal/external LCD )

I ran PassMark - G3D Mark performance test from https://www.videocardbenchmark.net/ and got around 8,500 , notably this is worse than the stock dGPU RX 5600M, which got around 10,000. I assume the poor performance is due to the PCIe 1x I was getting out of the PCE164P-N06.

 

I actually decided to return the Laptop and graphics card as I am now considering a GPD Win Max so I can't run any more benchmarks but I wanted to document that eGPU was working on a relatively cheap Zen 3 4800H laptop to give others build ideas.

@zdog291, Good to see this build. I actually bought this same laptop and am currently putting a build together using the ADT-Link R43SG M.2 eGPU adapter. It should have an x4 PCIe connection to the second M.2 socket. The 5600M dGPU is definitely a very strong discrete graphics card for a laptop in this price range. Unfortunately it means the system runs hot and loud. I will use an RX 5600 XT eGPU to see the performance discrepancy.

When I saw marketing photos of this laptop on Dell website, I was hoping the USB-C port was secretly a Thunderbolt 3 due to the Thunderbolt logo next to it. The production version only shows a DisplayPort logo next to the port. I looked at the laptop mainboard too and no Thunderbolt 3 controller was found so there's no hope for a surprise firmware/BIOS update to enable this functionality. Definitely let us know if you get a GPD Win Max!

What does the pcie lane layout look like? Can both slots have a full x4 connection at the same time?

@nu_ninja, Yes both M.2 slots have x4 connection. I will post HWiNFO64 with my build soon.
