Throttle GPU Power: Save 60% Energy with Minimal Performance Loss

Reduce GPU power from 250W to 100W with only 10% speed drop – a game-changer for efficiency.

Deep Dive

Reddit user milpster shares a PSA: test throttling GPU power limits to save tons of power with only minor performance deficits. On a dual Radeon VII setup, they reduced power from 250W to 100W per card, and speeds dropped by less than 10%.

Key Points
  • Reddit user milpster reduced GPU power from 250W to 100W per Radeon VII card—a 60% decrease.
  • Performance loss was under 10%, making it ideal for compute-heavy workloads.
  • Tools like MSI Afterburner or AMD WattMan enable easy power limit adjustment.

Why It Matters

Professionals can slash electricity costs and heat output without sacrificing meaningful performance for most workloads.
