Any benchmarks for Ryzen chips running with power restrictions? (alien.top)

A few days ago Tech PowerUp released a review of the 14900k with various power restraints. This was both telling and interesting for me, and something I really wish I had seen a week ago. However, those other chips are running at stock. It's not an apples-to-apples comparison. Is there anything similiar to that for any of Ryzen 7000 CPUs? I've read plenty of anecdotes, but such evidence is plentiful and all over the place.

Absolute balls-to-the-wall benchmarks are meaningful and have their uses, but when that's all you have, it's just a fruitless dick measuring contest. Why Intel is playing that game, I can't imagine since it's a really bad look, but that isn't the subject of this post.

If you do a google search for "[Ryzen CPU] Eco mode benchmarks" you should get a fair few results, though they'll probably be more from hobbyists than professional media outlets.

Ryzen CPUs have had an "Eco mode" option for a long, long time now. In the case of my 5800X, enabling Eco mode sets the max TDP at 65 watts, plus some other stuff. I get about 25%-30% power savings in exchange for a 10%-15% performance reduction, plus the CPU puts out a lot less heat, which is also nice, it's a very fair trade, but it is a trade.

Google "Ryzen Eco mode benchmarks," that'll get you started.

As others point out, there are several comparing Eco mode vs stock. I did my own analysis over a frequency/temperature/power range for a 7900X. 45 C to 75 C which covered CPU package power of 55 W to 120 W.

To get to a 7950X, multiply by about 1.20-1.25x for the performance at the same power. Graphs showing results are at the bottom. Results do not apply to the X3D.
