Intel's flagship Alder Lake processors developed an unexpected problem during tests: when using
Tested with Intel Core processorsi9-12900K and Core i7-12700K and Core i5 12600K, which showed the same tendency to decrease in performance when using inexpensive motherboards. During the tests, it turned out that the reason lies in the mismatch of the power subsystem of such boards.
Low-end motherboard models are not able todeliver the required power of 135 watts for a long time, and the minimum Power Limit 1 value required for their normal operation is 125 watts. At the same time, under load, they consume much more.
A decrease in performance was noticed whenputting processors into Boost mode. Intel Core i9-12900K showed a drop in performance by almost 30%, mostly it kept within 25-30%; Core i7-12700K lost 21-25% performance. The younger model - Core i5 12600K lost 7-9%.
As noted, the best decision when choosing a processor will be a motherboard based on the Intel Z690 chipset with a "10 + 1 phase" power supply, DrMOS integrated circuits and a current of 50 A.
