Power consumption and efficiency in mixed workloads
This is where AutoCAD comes in handy, because there are no performance-hungry rendering interludes. The CPU load is usually below 70 percent, often enough even lower, which reflects the normal workday quite well. Also, the Cadalyst run is fairly consistent, including power consumption on systems of varying speed. The Core i5-12600K takes them all and is even slightly below the Ryzen 5 5600X, but then the i7-12700K follows, with the Ryzen 7 5800X breathing down its neck. The i9-12900K can be found in the good midfield, whether with or without a blown up PL1.
Once again, you can put the score in relation to the power consumption in order to map the efficiency. The Core i9-12900KF is even 71 percentage points more efficient than the Ryzen 9 5950X. I’d rather not even write anything about the Core i5-12600K.
Full power during rendering
Here, the Core i9-12900KF is naturally at the very end and also behind the faster Ryzen 9 5950X. The i9-12900K, which I manually slowed down to 125 watts for PL1, on the other hand, collects in the midfield, because the gulping orgy is history after less than a minute. And it right now the best time to give Intel an earful for the aberrant PL1 at 241 W.
The layman is amazed and the expert is surprised. In fact, without the unlocking skills from Pat’s PL1 magic booth, the i9-12900KF is the most efficient CPU! All this was probably only because someone wanted to attack AMD’s many-cores in their very own field and so the Alder Lake now has to be brought to the boil by force. If you were to run all of these CPUs as originally planned in the specs, you would be a bit further behind in rendering, but not completely beaten. For this, the ecological factor would be priceless. Maybe we’ll see Fridays for real PL1 sometime, then the power outlet will have a breather while rendering.
