Hello,

Thanks for visiting the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,

The RAM is shared between CPU and GPU, and the GPU needs it for bitmaps, display memory, font cache,…

The Total memory size is less than 8G, I also buy another Jetson Orin Nano 8G from secondary supplier, the total memory is 7.2G. What are they different?

@1281641519 I believe there are some points should be clarified:

  • How the memory actual 8GB size is? 8x1024(G)x1024(M)x1024(K) ?
  • How to share/config GPU & CPU memory in JetsonBoard?

Well, I’m NOT expect on this, If you want to get more detailed info, I suggest follow these questions.
