So, the question then becomes is how do we know that the same isn't true for the 9700x? How do we know if they come out with a 9700 non x that there won't be even more power savings? We don't, not until they come out with one.
All signs points to the 9700X already being efficiency tuned out of the box. It's certainly possible that additional efficiency gains can be had (the same could also be said of the 7700 (non-x)) but the end result is not an interesting product on the efficiency front as there simply is not enough performance gains over last generation that would allow you to make massive cuts to the power consumption.
If we look at the 5.3 ghz OC power consumption that you are referencing it is within one watt of the 7700x in the 47 application average.
If we look at the performance of the 5.3 ghz we can see in the cinebench single thread that the 5.3 ghz OC gets 7.1 points per watt and the 7700x gets 5.5. In Cinebench that is a 29% better performance per watt for single thread. If we do multi thread the advantage is 10.2% in favor of the 9700x. If we do gaming the 5.3 ghz OC of the 9700x is 3.01 fps per watt, the 7700x is 2.66 fps, that means the 9700x gets 13% more fps per watt when overclocked to 5.3 ghz when compared to a stock 7700x. If the architecture wasn't any more efficient then we wouldn't be seeing these results. Maybe the architecture only shows it efficiency when you go up the wattage curve when compared to Zen 4.
You are trying to compare a tweaked config to a stock config, it should go without saying that's not an apples to apples comparison.
If you go back and look at TPU's review of the 7700X to compare apples to apples you can see the same OC setup (the exact same one you are using in your example so it's fair game) achieving a 21.56% increase n multi-threaded efficiency:
Now let's compare that to the 9700X in MT efficiency:
That is a mere 10.2% increase in efficiency over the stock 7700X. When you extrapolate the 7700X OC config onto the 9700X review data, which allows us to compare apples to apples, the 7700X OC 5.1 GHz setup is actually 11.36% more efficient in multi-threaded workloads than the 9700X.
Now let's look at gaming efficiency:
3.01 for the 9700X config:
4.85 for the 7700X OC config:
The 7700X tuned config is actually more power efficient than the 7700.
This is what I meant when I said there isn't enough performance headroom with the 9700X to make tuning the power interesting. There isn't a lot of power to shave off to begin with and Ryzen 7000 chips already get amazing results when tuned for power savings.
