As more AMD Ryzen 4000 laptops are coming to the market, I wanted to test one with eGPU. This being the first x4 M.2 eGPU.io build with one.
The Dell G5 SE 5055 has an all AMD configuration of Ryzen 7 4800H CPU and RX 5600M dGPU. I was also hoping there’s an unadvertised Thunderbolt 3 port on this laptop based on marketing photos [Best Buy]. Unfortunately it’s only a USB-C port with DisplayPort logo instead of Thunderbolt. M.2 eGPU through the ADT-Link R43SG is still a good option because there are two M.2 slots in this laptop.
I also got an ITX-sized RX 5600 XT for this build to compare eGPU performance vs the RX 5600M dGPU. PowerColor didn’t bring the RX 5700 XT to the US but this RX 5600 XT is a nice choice at $300 on Amazon. The design looks almost identical to RX Vega 56 Nano. However the cooler shrout is made of plastic on this Navi ITX card instead of metal in the Vega card. It doesn’t feel as sturdy in the hand.

I had the latest BIOS running on the Dell G5 SE. The installation process was straight forward. Open the plastic back cover (4x captive Phillips screws on the hinge area and 6x Phillips screws) and there’s full access to the motherboard. I inserted the M.2 eGPU adapter into the SSD2 M.2 slot and it was good to go.
All three GPUs showed up and worked without issues. I turned the RX 5600M dGPU off in Device Manager when I ran benchmarks on the iGPU and eGPU.

You may have seen reports of the RX 5600M dGPU in the 16-in MacBook Pro out-performing RX 5700 XT eGPU through Thunderbolt 3 interface. I think that’s subjective. As seen above the RX 5600 XT eGPU through M.2 interface performs better than RX 5600M dGPU. I will pair this RX 5600 XT in a Thunderbolt 3 enclosure to test with the 2019 16-in MacBook Pro next.
Regarding the Dell G5 SE laptop, it’s a great value for the performance. It’s unfortunately a typical gaming laptop that consumes a lot of power. The power brick is as large as the DA-2 220W. It makes sense because this laptop power adapter produces 240W. When both the CPU and dGPU are going full speed, the cooling fans are loud. The most telling results are 3DMarks. When the dGPU was running, the cooling system was overwhelmed and CPU performance was reduced significantly. Hopefully we will see AMD ultrabooks with Radeon iGPU-only and Thunderbolt connectivity.
