DGX Spark Power Optimization: Limiting GPU Cuts 36% Power
EAccelerate_42 · x · 2026-08-24
For the NVIDIA DGX Spark platform, using nvidia-smi to cap the GPU frequency at 2200MHz results in an 8–12°C peak temperature drop and 36% reduction in GPU rail power for dual GB10 A/B modules. The decode performance difference is within noise levels, with a total performance cost of only 1.34%.
