So, now it gets really interesting for the first time, because I now present you the power consumption values of the CPU. The pure package power of the respective SKU was measured across all games and during each individual benchmark run.
Power consumption compared to FPS
For a better illustration of the power consumption in relation to the FPS, I now show the already known FPS curves and the CPU power consumption in relation to each other. You can now select the same desired game in each of the three galleries and then compare these curves with each other. Very remarkable here is the curve of the Core i9-11900K, where you can see the PL1 and the drop of the curve after time very well. Now we know why Rocket Lake was so and rightly called a pompous sham giant. By the way, Control does not show any special saving effects but remains fully in line with the trend despite the limiter.
Well, I never! The Alter Lake S CPUs aren’t going to be…. Yes, they are frugal! The values are, despite the high PL1, so low compared to the Ryzen CPUs that I repeated the first measurements several times in shock, because I did not want to believe it. And yet it is reality and exactly what I had already spoiled earlier with actual relevant bar length. If you thought you were in for a surprise at Alder Lake S, here it is. Even if a little different than perhaps feared. And because it’s so nice, I first have the Package Power as a bar chart:
We also see in the sum of GPU and CPU (that belongs together, after all) that the faster CPUs naturally produce higher GPU power consumption. We already know the curves in a similar form from above and after that we also have the summary in the bar chart:
Efficiency of the CPU in Watt per achieved FPS
Of course, you always have to look at the power consumption in the context of gaming performance. Here I have simply calculated how many watts you have to spend per second for a single frame. Here Pat can now sit back and relax and have a coffee break together with Greta, while Lisa is called to the desk to do some important homework. It’s almost humiliating, unfortunately.
So I’m done with 720p for now and even if you’re not a stamp collector, you might have gained some new knowledge. And also for this there is the cumulation at the end in the conclusion.
