Passive cables can deliver 40Gbps at 0.5m and 20Gbps at up to 2m. Active cables can deliver the full 40Gbps up to the 2m limit.

 

You'll need an active cable if your thunderbolt cable is more than 0.5m long.

Hey guys,

 

I'd like to know what the difference between those cables is, because I have seen that passive Thunderbolt 3 cables are a bit cheaper than active cables.

What is the best choice for a eGPU?

 

Thanks in advance!
