Unknown equipment fanatics have actually run a burn-in examination on Intel’s 11th-Gen Rocket Lake cpu to subject its power usage under severe lots and also contrast it to its precursors from the Comet Lake-S household. It ends up the upcoming Core i9-11900KF CPUs can obtain very warm and also power starving under severe tons, much like their Comet Lake forefathers. Intel’s upcoming eight-core Core i9-11900KF ‘Rocket Lake-S’ cpus can allegedly warm up to 98C and also draw 250W of power throughout cardiovascular test. That suggests the chips ought to position well in our CPU Benchmarks Hierarchy, at the very least one would certainly really hope offered all that power usage, yet they’ll run warm much like the previous-gen Intel chips.

Although Intel’s latest 10th Generation Core ‘Comet Lake-S’ processors are rated for a 125W TDP, they can actually suck up to 250W ~ 330W of power when they boost on all cores for up to 56 seconds, allowing them to provide their maximum potential in situations where it is actually needed.

Intel’s public-facing specs list power consumption based on the default power level (PL1). There’s a big difference between the default power level and an all-core turbo power level (PL2), so you’ll need an advanced motherboard, a quality PSU, and a capable cooling system to tame the Comet Lake beast. That’s because Intel had to increase the PL2 level on its Comet Lake CPUs in a bid to make them more competitive against AMD’s Ryzen lineup.

Apparently, the same rules apply to Intel’s upcoming eight-core Core i9-11900KF ‘Rocket Lake-S’ processors that can heat up to 98C and pull 250W of power at 1.325V Vcore when running AIDA64’s FPU stress test, according to Chiphell. The test CPU was cooled down using an entry-level 360-mm closed-loop liquid cooling system. The chip’s exact clocks are unknown, but based on leaks, it should run at 3.50GHz by default and boost all of its cores to 4.8 GHz for short periods.

Being manufactured using a mature 14nm process, Intel’s latest enthusiast-grade processors with eight or ten cores are not exactly energy efficiency champions, which isn’t surprising because this node was not developed for CPUs that combine a high frequency and a high core count.

While the Rocket Lake-S CPU is based on a new microarchitecture and has several other advantages over Comet Lake-S processors, it looks like its thermals and power consumption will be comparable to those of its predecessors, at least as far as stress tests are concerned. Meanwhile, bear in mind that stress tests do not usually reflect real-world workloads, but are meant to reveal the weaknesses of your PC build.

As Intel is getting ready to release its 11th Generation ‘Rocket Lake’ CPUs this April, it has already begun to send its samples to a broad audience of its clients so they could prepare for the launch. As a result, certain test results will inevitably emerge well before full-fledged final hardware reviews show up. That said, the unreleased processors’ current test results should be taken with a grain of salt.
