I assume you don't magically lose bandwidth when running an M.2 to PCIe adapter, so if it's a PCIe 3.0 x4 slot, any GPU that isn't bottlenecked by only having 4 lanes should be fine. TechPowerUp has a writeup using a 980, it doesn't seem to bottleneck by much so anything around that performance level should be fine: https://www.techpowerup.com/review/nvidia-gtx-980-pci-express-scaling/. Did see some people on another forum saying Nvidia has blocked x4/M.2-PCIe functions so you can't even run at/with that so you may wanna look further into that and possible avoid Nvidia cards. But something around RX 580 level for more modern cards should only take a slight hit at most.

Hi everyone.

 

I'm thinking about connecting an external gpu to my HP 15s1079eq (ryzen 4700u) through m.2 as I have no thunderbolt. Which gpu would you suggest?

I've read that "high performance" gpus are pretty much usless if connected via m.2, but as I'm not an expert i would really appreciate if someone could give me an advice.

 

Sorry for my bad english.

 

Thanks! 🙂
