Today was the big day for Intel, its Comet Lake-S processors have gone on sale, the first reviews of the Core i9-10900K have started to come out and we already have a first extreme overclocking test with said processor, thanks to the well-known professional overclocker Elmor, which has managed to bring said chip up to 7.7 GHz, keeping all its cores active thanks to the support of the liquid helium, a material that offers a cooling capacity superior to liquid nitrogen.
It is clear that this type of overclocking is not viable for the normal user, in fact its usefulness is so limited that it has become more of a curiosity than anything else, but it does not cease to be impressive. At the moment those 7.7 GHz remain as the first world record for extreme overclocking with the Core i9-10900K without disabling any core, we will see if someone is able to overcome it.
The rest of the components used in this extreme overclock test were a motherboard ASUS ROG Maximus XII APEX, one of the best in its class, and a DDR4 G.Skill F4-4000C18-8GTRG (8 GB) RAM module, which reached 6.66 GHz, an equally impressive figure.
What does the media say about the Core i9-10900K?
The first analyzes confirmed that said processor had a high consumption and high temperatures, in fact it strongly recommended use an AIO type liquid cooling system with 360mm radiators to keep working temperatures under control. It is normal, the Core i9-10900K is manufactured in 14 nm ++, a process that no longer gives of itself, has 10 cores and 20 threads and reaches very high temperatures.
I was surprised to see the disparity of results in many analyzes. In some the Core i9-10900K shows average working temperatures of 60 to 70 degrees, while in others it reaches values of 80 and more than 90 degrees. The same happens with consumption, there are very marked discrepancies, so much so that the values in some analyzes point to 220 watts and in others to more than 250 watts.
Undoubtedly the most curious thing is that many of those values not only do not match the results of the first leaked analyzes from China, which were verified and confirmed, since they had samples of the Core i9 10-10900K, but they also do not match the results obtained by such reliable and recognized media such as Tom’s Hardware and Anandtech.
Precisely the latter is very clear in its conclusions, since it indicates that although the Core i9-10900K continues to lead in single-wire performance, its consumption is very high (254 watts) and its temperatures too, to such an extent that un 240mm AIO liquid cooling kit has problems to keep under control the working temperatures of said processor. This fits with those early reviews that recommended 360mm systems.
We can make it clear that the Core i9-10900K offers very high performance, both in single-wire, where it maintains the crown thanks to its high working frequencies, and in multi-wire, thanks to its 10 cores and 20 wires, but as a counterpart it has a very high consumption and very high temperatures. If you want more information, I invite you to review the analysis published by Dr. Ian Cutress in Anantech.
