NUC 11 BTMi9

[richard_branigan]

My setup:

NUC11BTMi9 with Nvidia 3060/16Gb ram/1Tb with FireCuda 2Tb

External display - Apple Pro Display XDR connected to Thunderbolt

This started out as a test but, can someone help me with understanding how this is working?

1. the display is connected to Thunderbolt port

2. nothing is connected to the Nvidia 3060

3. I did load a Microsoft Intel Thunderbolt driver

Is the Nvidia still in the graphics path here?

All seems to work fine to the display just curious about the internal video path.

thank you

Hello @richard_branigan

Thank you for posting on the Intel® communities.

In order to understand better this environment and the inquiry, could you please confirm the following details?

1- The Apple* Pro Display XDR is connected to one of the onboard Thunderbolt* ports in the NUC? (connected to the Intel® integrated graphics). Is this correct?

2- You have added a discrete NVIDIA* PCIe Graphics card to the NUC's PCIe X16 slot, but no displays are connected to it. Is this also correct?

3- What do you mean by "Is the Nvidia still in the graphics path here?" Could you please elaborate more on this inquiry? What specific information do you need? Why do you need this information? Are you trying to achieve any specific configuration or purpose?

Best regards,

1. That is correct, the display is connected to one of the 2 Thunderbolt ports

2. This model NUC came with an Nvidia 3060 pre-installed and there is no display connected directly to it.

3. There are times when (looking at Windows performance monitor) I see Intel being used, then at other times for example when decoding video via an Adobe App. I can see the Nvidia being used. Secondly, in some games it lets you select the Intel GPU or the Nvidia GPU. 

Maybe I am getting close to better understanding this but, it seems that the OS (Windows) can use either GPU and can still route through the discrete and utilize that Thunderbolt port. 

One example was using Adobe Media Encoder - To change a video format.

Monitor was connected to a Thunderbolt port. While watching performance monitor I could see the Nvidia being utilized (which is what I would want). The Intel (onboard GPU) was not being utilized at that time. 

Within Adobe Media Encoder I did not select anything related to the GPU, maybe it grabs best option? Not sure.

Hi @richard_branigan 

If  monitor is connected to the HDMI port and/or Thunderbolt port, the discrete graphics Nvidia 3060 is not in the graphics path and only Intel Integrated UHD Graphics is connected. In order to use the Nvidia Graphics, you need to connect the display to the Nvidia card connector and install the relevant Nvidia driver.

More information you will find in Multiple Display Configuration Options with Intel® NUC 11 Extreme Kit NUC11BTMi7 and NUC11BTMi9

and the Technical Product Specification.

Hello richard_branigan

After reviewing this further, we would like to inform you that the NUC comes with integrated graphics Intel® UHD Graphics for 11th Gen Intel® Processors and there is no mention that another video card is included, not even on the Product Specifications website Ark. (Probably, it was added by the seller or integrator).

The IGD works when quick Sync is required.

In order to use full video card bandwidth, it will be connecting video cables directly to the external video card.
