The lowest max power consumption among the boards I can verify is the WOLF-N4XP (VNXP-ORIN-NX) at 35 W, built on the Jetson Orin NX 16GB module with 100 TOPS (INT8 sparse) AI performance and 1.88 TFLOPS FP32. One caveat on the form factor: this board is a VNX+ (ANSI/VITA 90) compute node, not a 3U VPX board itself — the catalog files it in the same "Modular Compute Boards / Blades" group alongside the VPX products. If you need a strict 3U VPX form factor, the lowest max power figure I could verify is the WOLF VPX3U-XAVIER-CX6-HPC (WOLF-12TZ) at 70 W, which comes with the Jetson AGX Xavier Industrial module and 30 TOPS of AI performance (1.24 TFLOPS FP32). wolfadvanc... +4wolfadvancedtechnology.com ↗“VNX+ (ANSI/VITA 90) compute node with Jetson Orin NX 16GB”wolfadvancedtechnology.com ↗“power.max_power_consumption_w=70 W”wolfadvancedtechnology.com ↗“3U OpenVPX HPC module with Jetson AGX Xavier Industrial”wolfadvancedtechnology.com ↗“performance.max_ai_tops=30 TOPS”wolfadvancedtechnology.com ↗“performance.max_fp32_tflops=1.24 TFLOPS” wolfadvanc... +3wolfadvancedtechnology.com ↗“power.max_power_consumption_w=35 W”wolfadvancedtechnology.com ↗“compatibility.jetson_module=Jetson Orin NX 16GB”wolfadvancedtechnology.com ↗“performance.max_ai_tops=100 TOPS”wolfadvancedtechnology.com ↗“performance.max_fp32_tflops=1.88 TFLOPS”
For completeness, I could not determine a ranking across the entire group: several boards in this family (e.g., the Connect Tech Graphite VPX, Elma JetKit-3010, Curtiss-Wright VPX3-1711, Advantech MIC-332AO, and EIZO Condor T5-IOX 3U VPX) have no max power consumption value listed in the catalog, so they could not be compared on this measure. connecttec... +1connecttech.com ↗“Graphite VPX blade on Jetson AGX Orin Industrial”eizorugged.com ↗“Condor T5-IOX 3U VPX”
