[SOLVED] Is attaching a eGPU on this laptop possible?

[crasshassin]

I have a hp probook 430 g5 which has a usb c port on its side, but its got a small bordered "D" beside it leading me to believe that it is a usb c of the DVI type. Furthermore its listed as a usb c of the form "usb 3.1 type-c gen 1". Is attaching a eGPU possible via this sort of usb c?

No. You need a Thunderbolt port.

You can use an external GPU, only if your laptop comes with a Thunderbolt port...

I don't think using a type C USB port will work on an eGPU ? It doesn't support external GPUs. It must be a “Thunderbolt” port, which supports higher bandwidth as well. A thunderbolt uses 2 or 4 PCI express lanes so it can enable the access of external GPU to the processor.

USB TYPE C type is really a great standard, as it was created with the idea to bring uniformity in port's standard which it did, and is continuing to do so….

But when it comes to supporting external GPU, that is totally a different story…The port hardware doesn’t have the capability to do that…IMO, one needs thunderbolt hardware support for this….

You need to look at the PCIe bandwidth to run a GPU. USB Type C Gen2 doesn't give any PCIe lanes, which will make running a GPU pretty much impossible. Even Thunderbolt 3, which gives PCIe Gen3 x4 bandwidth, will bottleneck a GPU. For a GPU, you want at least PCIe x8.

BTW, even Even Thunderbolt 3 bottlenecks external GPUs due to bandwidth problems. The usb type-c port must support thunderbolt-3 for any of the external GPU docks to function, due to the bandwidth thunderbolt-3 provides.

BTW, if you anyone else plans to buy an e-GPU in future, assuming you have a compatible Laptop, then check the following links. It contains all the important info as well, including the e-gpu models and their prices. Give it a read, if you are interested.

I'm also planning to by an e-gpu for my laptop. I can't carry the PC everywhere, so this might come in handy, but they are still bulky. Though, some models are expensive.
