Nvidia GPUのPower Comsumptionを下げてみる

Posted at

概要

GPUの電気代を節約したいので、色々と試してみた。

環境

GPU: Nvidia RTX2060
OS: Ubuntu18.04

解像度を下げる

Nvidia X Sever Settingを開く。
defaultがFull Resolution(1920x1080)になってたので、Scaled(1366x768)に下げてみた

Powerを制限してみる

Poformanceを落とさずpower comsumptionを下げるのは25%くらいとの事だったので、160Wから120Wへ下げてみる事に。

125W以上にしろと言われたので、125Wに設定

PowerMizer

元からAdaptiveだったのでそのままに

結論

手っ取り早く、あまりデメリットが無い、解像度を下げるのが一番効果的なような。
