What actually happens when you take away the e-cores? That’s right, Alder Lake suddenly becomes even more economical in gaming than already proven! However, this also elegantly counteracts the term efficiency core and once again shows that these cores are actually almost completely superfluous in many scenarios (but not all). Once again, they mutate into thursty drinkers that no one actually needs when gaming. Sounds drastic, but unfortunately it is true. As always, the pure package power of the respective SKU was measured across all games and during each individual benchmark run. If the smaller CPU loses performance, it’s almost entirely because of the lower clock compared to the i5-12600K. The fact that the differences in some workstation applications are much bigger than in gaming will be part of the follow-up on Thursday.
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 game you want in each of the galleries and then compare these curves. 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 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.
And the Core i5-12400? This is the most mannerly candidate at the electricity counter and thus also the coming hate object of all electricity producers. The values are, despite the still so high PL1, so low compared to the Ryzen CPUs that I forgot to close the jaw again that dropped in amazement. And yet it is reality and exactly what I had already spoiled earlier with actual relevant bar length. Whoever believed that they would experience their blue miracle with Alder Lake S here: There it is, especially with the gutted i5-12400. And because it’s so nice, I also 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. The Core i5-12400 even beats the Ryzen 5 5600X by a long way, who would have thought that a few months ago!
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 final cumulation of all single results at the end in the conclusion on the last page.
