Hello community!
I am looking into purchasing the Intel ARC B580 and connecting it via USB4 and an eGPU Thunderbolt (?) enclosure, or through an OcuLink connection using a Dual M.2 adapter board.
My question is: will it work as intended? I heard that the B580 requires a feature called ReBAR to be enabled in the BIOS, however I wasn’t able to find anything related to it.
Does this make any sense at all, or is it just a waste of money?
Keep in mind framework 16 laptop do not have thunderbolt support. If I understand it right eGPU uses thunderbolt to handle it’s speed to the laptop if so then it might be hard.
It has USB4 support, which supports eGPUs
Well it depends if it does.
Since some 1 said too that it has 40Gbps but that doesn’t gurantee it supports eGPU.
Alot of eGPUS relays on needing thunderbolt 3 to work. Without it you won’t have a eGPU working.
The usb 4 spec is an evolution that includes thunderbolt features even though, for marketing reasons, they cannot call it thunderbolt.
I have two thunderbolt devices that work fine when plugged into the usb 4 ports.
So, thunderbolt eGPU will also work, if you get a thunderbolt spec cable.
But it will be limited due to it isn’t proper thunderbolt.
So the docks with thunderbolt 3/4 won’t work fully. Due to it
What specific features will not work?
no idea,
Couldn’t find any exact list of that. But all i found was statement that when a port isn’t fully certified and fully built to work for thunderbolt then there will be limitations when using thunderbolt docks, even issues.
So far i saw some 1 having dock issue for his 2 monitors so i asked them if the dock is a thunderbolt dock and if so i suggested him to try non thunderbolt dock and see if problem remains if not. Thne that is 1 issue you could get due to USB 4 isn’t fully thunderbolt supported/certified.
I have several thunderbolt devices I use all the time on my Framework 16’s and 13th’s including eGPUs; they work just as you’d expect them to.
That could be because ones you use are having no problems. While others here might be using other brands and other models that does bring up issues.
Possibly, but I haven’t found one that doesn’t work yet.
Edit: Note I’m speaking specifically on behalf of the Thunderbolt/USB4 functionality. I don’t believe I use anything that needs ReBAR, so that could be an issue with the B580…
