Only 512 cuda cores are detected

[danielcristianv]

I have a acquired a jetson ORIN NX board and it was specified that it contained 1024.
I run the deviceQuery executable from cuda samples and it only shows 512.
Where does this issue come from?
It is something wrong with the board and I need to replace it?

Hi,

Please enable all the TPCs and try it again.

$ sudo nvpmodel -m 0

Some nvpmodel mode only enabled 2 TPCs (max is 4 in Orin NX) to meet the power budget.
So the available GPU cores will be half. Please find the details in the below doc:

Thanks.
