PL4 GPU benchmarking?

Hello
I have a HP Spectre x360 15-eb1006nf laptop with a slow graphic card (Intel Iris Xe).
I have added in the spreadsheet the DeepPrime and DeepPrime XD times with this laptop and Photolab 7 (and also PhotoLab 5).
I am thinking about upgrading my laptop with an external GPU (eGPU) in order to get decent treatment times with DeepPrime XD.
My laptop has 2 Thunderbolt 4 ports with USB4 type-C and transfert rate of 40 Gbit/s (USB power, DisplayPort 1.4, HP standby and charge).
If some of you have an experience in this domain, I am interested.
