2021 14" Lenovo ThinkPad X1 Carbon 9th Gen [11th,4C,G] + GTX 1080 @ 32Gbps-TB4 (Mantiz Saturn Pro) + Win10
2021 14" Lenovo Thinkpad X1 Carbon 9th Gen
CPU: Intel Core i7-1185G7
iGPU: Intel Iris Xe Graphics
dGPU: MSI GTX 1080 Aero OC
Video Bus: PCIe v3.0 x16 (8.0 GT/s) @ x4 (8.0 GT/s)
Very much plug and play! I manually installed the Nvidia Geforce software so that I could keep the drivers up-to-date outside of Windows Updates.
CUZA-Z: (With 3rd party 2m TB4 cable)
I'm in the process of getting a TB4 cable as the one provided by Mantiz is TB3 and only 1m long. I purchased a TB4 cable to replace a 3rd party TB3 2m cable. Even though the enclosure doesn't have TB4 controller, the simple act of swapping the cable seems to have improved my CUDA performance. I will test with the original TB3 1m cable provided by Mantiz when I have a chance.
Being able to plug a single cable into the laptop and get access to a dGPU, speakers (through monitor output), mouse, keyboard, ethernet, webcam, wired DS4 controller and modmic wireless is amazing. Gaming performance is on par or better than my old 6th gen i5 desktop with the same GPU, but with all the portable convenience when we can travel again.
@nando4, I've actually seen very different readings depending on the connected enclosure with Tiger Lake hosts. Of the laptops I've tried, so far I could only conclude that it's on the laptop's firmware. The two examples are ASUS 14-in ZenBook Duo and Samsung 15-in Galaxy Book Pro. I connected the Galaxy Book Pro to 5 different eGPU enclosures and cards this past week and took same screen captures in AIDA64 and HWiNFO64; will be posting that build soon.
@nando4, I can disconnect my monitor and see if that changes the results? I'm also a bit weary of the PCIE 4x connection, when hwinfo reports that the port can go up to 16x - my guess is because the enclosure isn't TB4, I'm leaving bandwidth on the table.
