power-limit your GPU for local AI — cut 20% of the watts for ~1% less speed

Because AI inference is memory-bandwidth-bound, the last chunk of your GPU's power budget buys almost no extra tokens. Cap the wattage and you run… Aliteq Ravi Malhotra · Hardware Editor

Inference is bandwidth-bound — the last 5-10% of GPU power buys almost no tokens.

RTX 3090 → 280W: saves ~70W for under 1% speed loss. Free win.

RTX 3090 → 250-280W (from 350W stock): only ~5-10% loss, much cooler.

RTX 4090 → 350W (from 575W): ~90% of performance, ~40% less power.

Benefits: cooler, quieter, lower electricity bill, longer GPU lifespan.

One command: nvidia-smi -pl <watts(Linux) or MSI Afterburner (Windows).
