This is to be expected. Since 180Watt is not the default TDP of Ryzen 2700X, the default TDP is 105Watt. https://www.amd.com/en/products/cpu/amd-ryzen-7-2700x

Which mean the CPU is already shipped with the reasonable performance/watt TDP and over-TDP it will give diminish return in performance gain.

However, It would be interesting to see benchmark in much lower TDP than 105Watt and see how far the TDP can go down before big drop in performance.

Excellent look into this by user "The Stilt" can be found here: https://forums.anandtech.com/threads/ryzen-strictly-technica...

It looks something like this: 4GHz 120W, 3.8 90W, 3.6 65W, 3.4 50W, 32 42W, 3.0 33W, 2.0 13W. This excludes the SOC.

Stilt is a magician in getting peak performance per watt out of everything. Down to tweaking individual straps for memory timing on binary firmwares for amd graphics cards.

3.6 @65W is impressive, almost stock speed at nearly half tdp.

Basically a 10% performance penalty for a 45% power savings. And you might not even see that 10% performance penalty if you're machine is bottlenecked on memory/storage.
