Thunderbolt 3 and external gpu

Recommended Posts

Posted · Original PosterOP

Currently on the mobile version of the forum and I wasnt able to find the correct sub category so please excuse me.

 

Currently looking at running an external graphics setup and was wondering since egpus are bottlenecked by thunderbolt 3 is it possible to pair e.g. like how you can with ethernet cables for more bandwidth?

you might need to design the device from the ground-up to present itself to the host PC as two thunderbolt devices and any PCIe devices downstream as a x8 host

plus extra drivers for the PC to understand what's going on with those two thunderbolt connections

 

in which at this point you'd better be paid for that R&D

 

TL;DR: not readily, not realistically

IIRC Thunderbolt 3 has a 40 Gbps bandwith, and the most common Ethernet ports are 100 Mbps or 1 Gbps, so no, it wouldn't be better

You can find 10 Gbps ethernet ports but those are expensive (the cables too), so the technology won't allow you to get a faster external GPU because that would be extremely expensive by now, anyway the performance loss is minimal (yeah, 10/20 fps is minimal) because it's not that common to run a laptop as a desktop (something that, imo, would be cool af but we need cheaper docks and better cooling solution in laptops)

OP's talking about teaming two thunderbolt connections and is bringing up network teaming as an example ._. there's no such thing as Thunderbolt over Ethernet.

Okay, didn't get the reference lol

I don't think there are any laptops ready to use double thunderbolt 3 at full bandwidth, and haven't seen any enclosure for it neither
