It is clear that the Core i9 10900K is a very powerful processor. Your settings ten cores and twenty threads, together with its frequencies of up to 5.3 GHz in turbo mode and its high IPC make it one of the highest performance general consumption processors that currently exist, although it has an important counterpart, and that is that its consumption is very high and their working temperatures too.
Intel introduced the new Comet Lake-S processors at the end of last April, but their availability It won’t be a reality until the middle of May, which means that we will still have to wait until the publication of the first official analyzes of this new generation of high-performance CPUs, although thanks to the “rush” of some media we have already had the opportunity to see some preliminary tests , and the truth is that things do not look too good.
As we have indicated the performance of the Core i9 10900K is beyond doubt. Intel has fine-tuned the 14nm ++ process to the maximum To design a 10 core and 20 wire chip capable of loosely overcoming the 5 GHz barrier, but the result in terms of efficiency and temperatures has been more than questionable.
Core i9 10900K: 93 degrees at stock frequencies and 234 watts of consumption
As we can see in the attached image the Core i9 10900K reaches 93 degree peaks working at its default frequencies, that is, at 4.8 GHz in turbo mode with all cores active, and consumption shoots up to 234 watts. The user who did this test has confirmed that they used an all-in-one liquid cooling kit (AIO) with a 240mm radiator, which means that to keep the temperatures of the Core i9 10900K under control we are going to need very powerful cooling.
For technology Thermal Velocity Boost from Intel to work the chip has to be in about 70 degree, a temperature that, in this particular case, seems almost impossible, even if we mount a high-performance custom liquid cooling system. It goes without saying that a processor running at 93 degrees enters the thermal throttling range, that is, the working frequencies begin to be reduced to reduce heat and avoid damage at the silicon level due to excess temperature.
For comparative purposes I remind you that a Ryzen 9 3950X, which adds 16 cores and 32 threads, it has a load consumption of 220 watts and with a 240mm liquid cooling kit it stays around the 70-72 degrees no problem. It is clear that the Zen 2 architecture is more efficient both in terms of consumption and temperatures.
The 14nm process has become a huge barrier for Intel in the high-performance desktop CPU market, and as our regular readers will know, it will still have future interaction in the series. Rocket Lake-S, which will implement an adaptation of the Willow Cove cores (Tiger Lake in the 10nm ++ process) to the 14nm +++ process.
