Intel has changed the documentation for Comet Lake-S, and now everyone found out their real consumption

Intel подменила документацию на Comet Lake-S, и теперь все узнали их реальное потребление

That Intel Comet Lake-S have a good appetite, was known before its release. Itself Intel traditionally does not advertise information about the power consumption of their processors, by specifying in the specs only the TDP that shows only part of the picture. However, the resource ComputerBase noticed that Intel has replaced the reference documentation on the new processors, and corrected versions were more honest consumption characteristics.

For a start it is worth mentioning that Intel uses two level of power consumption (Power limit, PL) in the description of their processors. Claimed by Intel, the TDP corresponds to the first level of energy consumption PL1 – consumption of the processor with a base clock frequency. For example, the flagship Core i9-10900K when working on the basic 3.7 GHz under high multithreaded load, should consume not more than 125 watts.

In turn, the second level PL2 corresponds to the maximum consumption of the chip, which it can achieve the automatic overclocking to the highest frequency. His company does not advertise Intel expected, but it largely corresponds to the actual peak power consumption of a processor.

That is the peak value of PL2, Intel and began to manipulate the documents to Comet Lake. In the previous technical paper No. 615211-004 she pointed out that the level PL2, you can determine PL1 by multiplying by 1.25. That is, for example, for the Core i9-10900K second level of power consumption was to be 155 watts.

However, the resource ComputerBase found that in reality the power limit PL2 for this processor set to 250 watts. For the rest of the chip values in the old version of the document has also been significantly underestimated.

Now, on the Intel site there is a new version of the same technical document with numbered 615211-005in which the values PL2 forwarded to higher values.

Our test lab has verified that the presented German colleagues and the specified Intel in the new version of the document data is correct. Thus, Core i7-10700 and Core i9-10900 with TDP to 65 W in reality can consume up to 224 watts. Intel Core i5-10400 may require up to 134 watts and 35 watts Core i9 chip-10900T – a considerable 123 watts. The smallest gap in consumption levels PL1 and PL2 boasts a Core i7-10600K, which the value is equal to 125, and 182 W, respectively.

As you can see, changes have been made to all tables, which Intel showed the limits PL1 and PL2 for members of the Board of the family Comet Lake-S.

Thus, users now finally got full information about the energetic and thermal characteristics of the new processors Intel, which gives them the possibility of a more balanced approach to the choice of cooling systems, motherboards and power supplies.
