Cinebench Performance Per Watt

Looking at the Cinebench performance efficiency data, the Ryzen 9 7900 non-X is absolutely superb. In fact, the only better option in our chart is a 32-thread Ryzen 9 7950X with a massively constricted power allocation.

The Ryzen 7 7700 does incredibly well, too, and it manages to outperform any of the stock-clocked competitors in our efficiency data.

As is clear, the search for higher frequencies is not good for the Zen 4 power efficiency equation. That’s where one-click PBO can be beneficial though; you can run the chip efficiently for general usage and then crank up the power allocation when certain tasks dictate.
