The emulating mode setting of Jetson AGX Orin Developer Kit

I’m using Jetson AGX Orin Developer Kit.

And I have two questions about Emulating mode.
When I used the following command for emulating Jetson AGX Orin 32GB.

$ sudo ./ jetson-agx-orin-devkit-as-jao-32gb mmcblk0p

Develop for All Six NVIDIA Jetson Orin Modules with the Power of One Developer Kit | NVIDIA Technical Blog

The GPU clock is not 940MHz but 816MHz as follows.

Question 1)
Does this mean Jetson AGX Orin 32GB emulating mode setting is as follows.

Jetson AGX Orin 32GHz Spec(Emulating Mode)
Real GPU Clocks: 816MHz
Cuda Core: 2048 Core
Tensor Core: 64 Core

Jetson AGX Orin 32GHz Spec:
Real GPU Clocks: 930MHz
Cuda Core: 1792 Core
Tensor Core: 56 Core

Question 2)
And total work loads are similar as follows?

Cuda Core Work loads(Real) : 930MHz * 1792 = 1,666,560
Cuda Core Work loads(Emulating) : 816MHz * 2048 = 1,671,168
Cuda Core Work loads(Real) : 930MHz * 56 = 52,080
Cuda Core Work loads(Emulating) : 816MHz * 64 = 52244

That seemes due to the NVPModel not set to MAXN.

Dear @kayccc,

Thank you for your information.
I understood that the GPU clock is set to 940MHz by setting NVPModel to MAXN.

I want to ask two more questions?

If so, is the number of cuda cores and tensor cores are decreased when jetson-agx-orin-devkit-as-jao-32gb is set?

Cuda Core: 2048 Core → 1792 Core
Tensor Core: 64 Core → 56 Core

Question 4)
Is there any way to confirm the number of Cuda core and Tensor Core?


Yes, CUDA core and Tensor Core will change when emulating.
You can run deviceQuery sample to check the current hardware status.


Dear @AastaLLL,

Thank you for your information.

Can I get Tensor Core Number by deviceQuery sample?
I confirmed there is a code for Cuda core as follows.

    printf("  (%03d) Multiprocessors, (%03d) CUDA Cores/MP:    %d CUDA Cores\n",
           _ConvertSMVer2Cores(deviceProp.major, deviceProp.minor),
           _ConvertSMVer2Cores(deviceProp.major, deviceProp.minor) *

However, I cannot find the code for Tensor Core.



You can calculate it based on the CUDA cores amount.

On Jetson, GPU is composed of TPCs.
One TPCs have 256 CUDA cores + 8 Tensor Cores.

So for example, if 1792 cuda cores are reported.
This indicates that 7TPCs are enabled in the devices and it should have total of 56 Tensor Cores.

Dear @AastaLLL ,

Thank you for your information.
I understood.
