Mohammednt0 Posted February 19, 2019 Share Posted February 19, 2019 According to Thunderbolt site they claim that TB3 can provide speed Up To 40 Gbit/s ! But TB3 USB-C is configured with 4 PCIe lane designs which can provide only 32 Gbit/s ! (according to wikipedia) So there is a bottleneck here !! TB3 USB-C should not be able to throughput more than 32 Gbit/s so how they are saying 40 Gbit/s !? Link to comment Share on other sites More sharing options...
+virtorio MVC Posted February 19, 2019 MVC Share Posted February 19, 2019 (edited) I don't know all that much about this, but I believe the DisplayPort and USB 3.1 lanes are different, so when you include those, that's where your 40 Gbps limit comes into play. Edit: with literally < 10 seconds of Googling, I found this PDF which explains it all - https://thunderbolttechnology.net/sites/default/files/Thunderbolt3_TechBrief_FINAL.pdf Link to comment Share on other sites More sharing options...
