Orin Nano vs Super Orin Nano

I have recently acquired a Jetson Orin Nano super development kit 8GB RAM, this I planned to use as a lower power alternative to the Jetson Orin Nx (following the logical order of the device family.

I was surprised when I booted up the device (flashed using the SDK manager with Jetpack 6.2.2) that the only available power modes were 15w, 25W and MAXN SUPER mode. I was expecting a 7, 10 and 15W split like the original Jetson Nano (non-Orin).

After some research I have seen in some places that this is supposedly simply a software rebrand of the Jetpack for Nano to boost it to a more performant configuration. But I have also seen other people say elsewhere that the power rails on the Jetson Orin Nano super dev kit are now different and cannot go below 15W config.

Could i gain some clarification -

  • Can I reintroduce the 7W limit on my jetson orin nano super dev kit?
    • If so, with what Jetpack version?
  • Are the “original” Jetson Orin Nano dev kit hardwares available from suppliers (non-super)

Thanks,

Cameron

Based on the provided context, I’ll clarify the differences between the Jetson Orin Nano and Jetson Orin Nano Super development kits, as well as the power modes available on these devices.

Jetson Orin Nano vs. Jetson Orin Nano Super:

The Jetson Orin Nano Super development kit is not just a software rebrand of the original Jetson Orin Nano. While it’s true that the Jetson Orin Nano Super uses a similar hardware configuration as the original Jetson Orin Nano, there are some key differences.

The main difference between the two is the power budget and the available power modes. The original Jetson Orin Nano has a power budget of 10W, with available power modes of 7W, 10W, and 15W. In contrast, the Jetson Orin Nano Super has a power budget of 25W, with available power modes of 15W, 25W, and MAXN_SUPER mode.

Power Modes:

The MAXN_SUPER mode is an experimental mode that allows for a maximum number of cores and clock frequency for CPU, GPU, DLA, PVA, and SOC engines. This mode is only available on the Jetson Orin Nano Super development kit.

The 7W power mode is not available on the Jetson Orin Nano Super development kit. This is because the power rails on the Jetson Orin Nano Super dev kit are different from those on the original Jetson Orin Nano dev kit.

Reintroducing the 7W Limit:

Unfortunately, it’s not possible to reintroduce the 7W limit on the Jetson Orin Nano Super development kit. The power modes available on this device are fixed and cannot be changed through software updates or configuration changes.

Jetpack Version:

The Jetpack version used to flash the device does not affect the available power modes. The power modes are determined by the hardware configuration of the device, not by the software.

Original Jetson Orin Nano Dev Kit Hardware:

The original Jetson Orin Nano dev kit hardware is still available from suppliers. However, it’s worth noting that the original Jetson Orin Nano dev kit has a different power budget and available power modes compared to the Jetson Orin Nano Super development kit.

In summary, the Jetson Orin Nano Super development kit has a different power budget and available power modes compared to the original Jetson Orin Nano dev kit. The 7W power mode is not available on the Jetson Orin Nano Super development kit, and it’s not possible to reintroduce this power mode through software updates or configuration changes.

Hi,

Please refer Support for Jetson Orin NX and Jetson Orin Nano in the Jetson Power Estimator Tool to customize the power mode.

Super mode just a software update, please refer Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation to flash with jetson-orin-nano-devkit instead of jetson-orin-nano-devkit-super configuration.

Thanks
