Intel Rocket Lake Core i9 processors can reach temperatures of 98 degrees with 250W power consumption.
Some hardware enthusiasts conducted a stress test on the 11th generation Intel Rocket Lake processor to reveal power consumption under extreme loads and compare this with previous processors from the Comet Lake-S family. As a result, it turned out that the upcoming Core i9-11900KF processors could overheat and consume power under load, just like their Comet Lake ancestors.
Intel’s upcoming 8-core Core i9-11900KF Rocket Lake-S processors can heat up to 98 degrees and draw 250W of power, as claimed during stress tests.
Even though Intel’s latest 10th generation Core Comet Lake-S processors are rated at 125W TDP, all cores draw their maximum potential by drawing 250W to 330W when under full load for up to 56 seconds.
Intel’s public specs list power consumption by default power level (PL1). There is a big difference between the default power level and the all-core turbo power level (PL2). That’s why you’ll need an advanced motherboard, a quality power supply, and a good cooling system to tame the Comet Lake monster. This is because Intel had to increase the PL2 level in Comet Lake CPUs to make it more competitive against AMD’s Ryzen series.
According to Chiphell, the same rules seem to apply to Intel’s 8-core Core i9-11900KF Rocket Lake-S processors, which can heat up to 98C while running AIDA64’s FPU stress test and draw 250W at 1.325V Vcore. The test processor was cooled using an entry-level 360mm closed loop liquid cooling system. The clarified frequencies of the chip are unknown, but according to leaks, it seems to run at 3.50 GHz by default, with all its cores rising to 4.8 GHz.
Manufactured using a mature 14 nm process, Intel’s latest 8 or 10-core processors aren’t exactly energy efficiency champions. Of course, this is not surprising. This is because the node was not developed for processors combining high frequency and high core count.
The Rocket Lake-S processor is based on a new micro-architecture and while it has many other advantages over Comet Lake-S processors, its thermals and power consumption seem comparable to previous ones, at least as long as there are stress tests. Let us underline that stress tests generally do not reflect real-world workloads but aim to reveal the weaknesses of your computer structure.
