Simulation of Nvidia Jetson & Co

Hey folks,
As title, I was wondering if it was possible to simulate the computation capability by Nvidia Jetson Families (E.g number of cores, Ram…).
I need to start some experiments in order to check the computational time over a limited hardware as Jetson Nano etc…
Is there any way to simulate it? Is it possible from pytorch to do it?
Thanks in advance for your possible information.
