Script or app to load GB10 GPU to test for maximum power?

This is the Spark-specific tool to check for the USB-C PD issue.

GPU PD Throttle Check Tool

The suspected PD throttling issue has been consistent enough that I wanted to create a quick tool to check for the failure state. Some noodling around with Claude resulted in: It checks to see if a GPU load runs over or under a default clock speed threshold (defaults to 1400MHz) over a number of samples (defaults to 20 samples spaced at about 0.5s). A GPU in a good state should hit ~2400MHz. Mine in a bad state are showing 500-850MHz, even though the power state is still showing P0. Happy…

Run it. If you have the issue, unplug your device from the wall AND from the brick, wait a bit, plug it all back in and restart.
