2018 15" MacBook Pro (RP560X) [8th,6C,H] + GTX 1080 Ti @ 32Gbps-TB3 (ASUS XG Station Pro) + macOS 10.13.6 & Win10 [OliverB]
Thank you, @oliverb! Hm... can't really understand why results in benchmarks higher (Superposition, Valley) when bandwidth is lower... MacBook better CPU (6c/12t)?
It's the notebook. The 15-inch MacBookPro has very powerful TB3 ports. It has 4 PCIe lanes directly connected to the CPU. The difference is notable.
I am not sure if there are other notebooks with this feature. @itsage may know more about it.
