Is SLI with razer core possible?

[CainCo]

I have a question about the razer core, what if you use TWO razer cores on the new macbook (since there are MANY of thunderbolt3 port), can you do SLI with it? If yes, what about 4?

[Oswin]

i think you cant, because how are you suppose to connect the SLI bridge?

[TheRandomness]

No because you'd also need a motherboard that supports it.

in theory yes, in real life no

I bet you could get it to worK... but with MUCH fiddling around

no sli doesnt support anything under a 8x by 8x lane configuration. the razer core only provides 4 lanes of throughput through thunderbolt 3 so its only good for a single card

sli: no

cfx: maybe, if you hack it to make it compatible

that makes much more sense

yea i guess i can't cuz it only has x4 PCIE lanes

WAIT, Xrossfire supports x4 by x4, maybe that's possible

again no both the cards need at least x4 bandwidth for both cards and having 2 cards over an x4 interface will run them at x2 x2 so it is not possible.

do they share pcie lanes tho?

yeah they do. you need bandwidth for both gpus

broke my dream lol

It is possible to make an eGPU SLI via Thunderbolt but very difficult. see here
