Cuda application performance decrease from xavier nx to orin nx

Hi,
I have a c++ application that heavily relies on cuda for GPU acceleration running on the jetson Xavier nx with cuda 10.2. I recently upgraded the board to the Orin nx with cuda 11.4 and noticed that compiling with the native CMAKE Cuda architectures for both that the performance on the Orin significantly declined. I’m looking into using some of the profiler tools to see what’s going on with the gpu usage and runtime differences between the two boards but I’m hoping someone may have an idea off the top of their head why there might be a performance degradation as I upgrade to a newer and more powerful gpu?

Hi,

Have you maximized the device’s performance?
It’s expected to align the power mode before comparing the performance.

Thanks.
