Power consumption of 10-core Intel Core i9-10900F (Comet Lake-S) reaches 224 watts (3 photos)


The energy consumption of modern processors is notalways corresponds to the parameters declared by the developer. So when testing a 10-core Core i9-10900F processor with a locked multiplier, enthusiasts received very unexpected results. The tested processor is the second fastest in the Comet Lake-S line and has a rated TDP of 95 watts.

During testing, 10-core (20 threads)Core i9-10900F processor with a base frequency of 2.8 GHz and loading all the cores showed an energy consumption of 170 watts. When working in Boost mode with a frequency of 4.5 GHz, power consumption reached 224 watts. Earlier, a message appeared on the network that the flagship Core i9-10900K processor (10 cores, 20 threads) has a power consumption of up to 300 watts. As a result, the power consumption of the Core i9-10900F processor is comparable to and even exceeds the power consumption of a Nvidia RTX 2080 class graphics card.

When testing, the system was usedcooling system consisting of an air cooler with five heat pipes and a water cooling system with a 120 mm radiator. The temperature of the Core i9-10900F processor during testing ranged from 80 to 90 degrees Celsius.


Thus, for normal operation, allowingto get the declared performance from the Core i9-10900F processor, desktop systems should be equipped with an effective water cooling system with a radiator length of at least 240 mm.

Previous trials in which I participatedCore i9-10900K processor, showed that the high performance required for complex calculations is achieved only with a full load of all cores. Therefore, when buying such processors, the need to create an effective cooling system should be taken into account, which carries additional costs.


Intel Core 10th official launchgenerations (Comet Lake-S) using motherboards with an LGA1200 connector will be held on April 30 or so. And processors will enter the market in another month - May 27. After that, they will certainly undergo more qualified and detailed testing, which allows them to form an objective opinion about the energy efficiency of systems.
