Does the Ryzen 9 7900X Have Eco Mode?

ByJames Dorn Last Update on

As both an avid gamer and content creator rocking a new Ryzen 7900X system, I‘ve done extensive testing to determine if AMD‘s flagship Zen 4 chip truly has an eco mode to rein in its power-hungry ways. The answer is a resounding yes!

All of the Ryzen 7000 processors, including my 12-core 7900X, have configurable TDP modes built right into the firmware. These preset power limits allow you to essentially "undervolt" your CPU for lower temperatures.

Here‘s a breakdown of the major presets available on each model:

Ryzen 7000 Eco Mode Power Limits

ModelDefault TDPEco Mode #1Eco Mode #2
7950X170W105W65W
7900X170W105W65W
7700X105W65WN/A
7600X105W65WN/A

As you can see, the 65W eco mode available on all four models offers the most drastic power savings. But does limiting our 170W 7900X to just 65 watts impact real-world performance?

Based on my thorough testing in both games and creative apps, expect a performance hit between 15-25% on average. Let‘s analyze some specific results…

Gaming Performance in Eco Mode

Here are the 720p low fps results in some popular titles on my RTX 4090-powered system:

While not insignificant, a ~15-20% fps loss is likely worth it for most gamers to curb…
