Jetson Thor vs Drive Thor - Power Tree Architecture Differences?

Robotics & Edge Computing Jetson Systems Jetson Thor

Hi NVIDIA Community,

I’m evaluating the Jetson Thor dev kit for power solution benchmarking and have questions about the power tree architecture.

Background:
Understanding that Jetson Thor and Drive Thor share the same SoC, I’m interested in the power delivery differences between the two platforms.

Questions:

  1. Power Tree Comparison:

    • Does Jetson Thor use the same power devices (PMICs, buck converters, DrMOS) as Drive Thor?

    • If different, what are the key variations in the power architecture?

  2. VRS Specification:

    • Which VRS spec version does Jetson Thor implement (VRS 10/11/12)?

    • Are there any power rail differences compared to Drive Thor?

  3. Measurement Access:

    • Does the Jetson Thor dev kit provide accessible test points for power measurements (voltage rails, current monitoring)?

    • Can we capture load transients and dynamic power behavior?

  4. Workload Equivalency:

    • Are the demos/benchmarks on Jetson Thor representative of Drive Thor automotive workloads?

    • Can we stress-test the power tree under realistic ADAS/autonomous driving scenarios?

Use Case:
Evaluating power solution performance for automotive applications and need to understand if Jetson Thor is suitable for applicative power measurements that would translate to Drive Thor deployments.

Any documentation, schematics, or guidance would be greatly appreciated!

Thanks in advance!

They are not able to compare due to the entire board and peripherals requirements are difference.
Jetson Thor devkit is 130W, but DRIVE Thor devkit is 230W.
Jetson Thor doc: Jetson Download Center | NVIDIA Developer
DRIVE Thor doc: NVIDIA DRIVE Documentation | NVIDIA Developer

That should be VRS10 on Jetson Thor devkit.

Please refer to Jetson Thor Product Family — NVIDIA Jetson Linux Developer Guide
Tegrastats Utility — NVIDIA Jetson Linux Developer Guide

No, we don’t have those demo or tools.

Thanks for getting back to me!

Do these toolkits use same SOC? Additionally, would be able to share block diagram of power tree on Jetson Thor

The tegrastate tool can be used on both Jetson Thor and DRIVE Thor.
For block diagram and relevant info, please find them from their documents.
