Radeon Chill

Radeon Chill

Another new feature you can enable in the Radeon Software Crimson ReLive Edition is Radeon Chill. By design it will reduce excessive GPU power consumption while delivering the same gaming experience for the end user. It does to by lowering your framerate in situations where it can allow to do so. It is a bit hard to explain, but we'll give it a try.

Radeon Chill basically monitors user inputs in order to determine whether or not quick motion is happening on the screen during a game. If the user is standing still and the display is mostly static, Radeon Chill quickly scales down frame rates to a lower threshold in order to save power.  The Radeon Chill features up to 31% lower average GPU power in certain games.
  

The moment as the user begins moving or interacting with the scene, Radeon Chill responds by instantaneously increasing frame rates to preserve a sense of fluid motion and responsiveness. Meanwhile, at all times, Radeon Chill avoids running the game at excessively high frame rates that would waste power with little or no end-user benefit. So basically this algorithm detect fast motion, of there isn't any, the framerate can be dropped a notch to preserve on power and load levels.
 

 
Radeon Chill has the potential to reduce the GPU’s power consumption, heat production, temperatures, and cooling noise without perceptibly altering the gaming experience.
  

 
In the above example with World of Warcraft the FPS average is measurably higher with Radeon Chill deactivated, roughly 125 FPS compared towards 62 FPS with Radeon Chill enabled. Benefits of Radeon Chill will vary depending on the game and on the performance of the system in question and your experience and your experience with Radeon Chill may differ across game titles, so we encourage you to test it for yourself.   

Radeon Chill is accessible through Radeon Settings. 1. Click the Gaming tab 2. Select Global Settings 3. Select Global WattMan Note: EULA must be accepted 4. Scroll down to Radeon Chill and toggle the global switch to ‘On’ Radeon Chill also has controls here to set a Global Hotkey that will allow a user to disable or enable Radeon Chill at any time while gaming. We're not sure if this new feature will become a big thing, we doubt it. AMD does also, the featrue as such is disabled by default.
