2021 15" Dell XPS 15 9510 (RTX3050) [11th,8C,H] + RTX 2060 @ 32Gbps-TB4 (Lenovo BoostStation) + Win11
2021 15" Dell XPS 15 9510
CPU: 11th Gen Intel(R) Core(TM) i7-11800H
dGPU: NVIDIA RTX 3050 Ti 4GB [45w]
OS: Windows 11 Build 22471
Laptop Screen: 15.6" UHD+ (3840 x 2400) InfinityEdge Touch Anti-Reflecitve 500-Nit Display
External Monitor: Dell U2414H (1920 x 1080)
- Use DDU to remove old drivers
- Installed latest driver from NVIDIA without GeForce Experience
- Plugged in BoostStation
- Ran the NVIDIA installer again and both the internal and external GPUs are happy.
Note: Originally I followed the following steps but found that the internal GPU (RTX3050 Ti) stopped working with Code 31.
Turn on BoostStation Wait for LED to flash Plug in to Laptop while logged in and on Desktop Run Windows Update Allow Windows Update to download NVIDIA Display Driver

1: Connected direct to eGPU. Lots of stuttering in the benchmark despite the figures.
2: Connected via USB-C to HDMI Cable.
Having trouble getting 3DMark installed on the machine so will look at alternatives to benchmark.Fresh install of Windows 11 and didn't have a problem installing 3DMark. Need to work out why the performance is worse on external monitor now; would have expected it to be better.3DMark is showing a performance increase now! Haven't rerun the valley tests.
@joe377, are the clockspeeds the same with external monitor plugged in?
Edit: Another thing I wanna add is, a dekstop RTX 2060 is almost twice as fast as an 45W RTX 3050 Ti so the numbers do lineup. I may be mistaken but I think TigerLake has reduced the eGPU to internal display bottleneck. if that's true and the fact that PCIe 3.0 X4 is not small enough to noticeably bottleneck the GPU they all kinda lineup, then again i could be wrong and be mixing things up here but that's my take.
@Rog195 just tried disabling the RTX3050 Ti via device manager and have updated the results in the first post. There is a performance increase but there is still a lot of stuttering during the benchmark.
Do you get stutters even when connecting the display to the laptops integrated graphics? I assume you just want to use your external monitor as the main monitor since the performance gains are very well with in line with the what you get from going from an RTX 3050 Ti(45W) to an RTX 2060(160W).
@rog195, no stuttering when using the internal graphics with an external display. Yeah the performance gains are what I expected, only reason to use an external montor is for convenience really and maybe a slight performance boost as the graphics card can output direct.
@joe377, Keep it connected to the iGPU then. You can also do some testing like, have you tried with other monitors? have you tried the booststation with other TB3/4 laptops?
@rog195, just added a Valley benchmark to my previous build (2017 13″ MacBook Pro [7th,2C,U] + RTX 2060 @ 32Gbps-TB3 (Lenovo BoostStation) + Win10) getting better performance on my new laptop which is good news.
Updated to Windows 11 this week and managed to get 3DMark working, added some benchmark results to the original post. Seeing a performance gain now when using an external monitor connected to the eGPU.
