The Jetson Orin NX 16GB is your best fit. It has 8 CPU cores and a default power range of 10–25 W, so it stays inside your 25 W cap. It's the only Jetson production module with more than 6 CPU cores whose top rated power in default mode is 25 W or less. nvidia.com +1nvidia.com ↗“power.power_envelope=10-25 W”nvidia.com ↗“compute.cpu_cores=8”
- Its CPU is listed as an 8-core Cortex-A78AE. nvidia.comnvidia.com ↗“8-core Cortex-A78AE, 16GB LPDDR5”
- Watch the power mode: In Super mode, its power range goes up to 10–40 W. To stay under the 25 W cap, run it in default mode. nvidia.comnvidia.com ↗“power.power_envelope_super=10-40 W”

Some modules have more cores, but their rated power goes above 25 W:
- Jetson AGX Orin 64GB: 12 cores, 15–60 W. nvidia.comnvidia.com ↗“12-core Cortex-A78AE, 64GB LPDDR5 (204.8 GB/s), dual NVDLA, 15-60W”

The low end of their ranges is under 25 W, so a lower-power setting might fit your budget. However, I couldn't find how many CPU cores stay active at those lower settings. Check that before you count on 12 cores at 25 W.
