Alleged Intel Alder Lake-S Desktop CPU Examined, Runs Actually Scorching at Up To 93C Whereas Consuming 250W of Energy

Written by Jeff Lampkin

Intel’s Alder Lake-S Desktop CPUs are going to supply an enormous efficiency improve over the present 14nm components however will achieve this whereas operating actually scorching and consuming a number of energy.

Intel’s Alder Lake-S Desktop CPUs Allegedly Run Actually Scorching & Eat A lot of Energy

The Intel Alder Lake-S Desktop CPU testing was executed by WolStame over at Weibo who’s Lenovo’s China Gaming Desktop & Product Planning supervisor. In his submit, WolStame states that it is not solely the NVIDIA GeForce RTX 3090 graphics card that would want 350W to run at its fullest potential & follows up with what appears to be early numbers of an Intel Alder Lake-S chip operating at Lenovo’s take a look at labs.

The testing was executed with AIDA64 and the respective energy/temperature figures had been reported in HWiNFO. The AIDA64 stress take a look at could be very brutal and should not be in contrast with customary workloads reminiscent of gaming and rendering which places method much less stress on the CPU cores. It seems to be like each instruments aren’t reporting the proper specs for the Intel Alder Lake chip however we do get to see energy & temperatures of the chip.

It seems to be just like the chip could possibly be the flagship Intel Core i9-12900K solely based mostly on Home windows 11 process supervisor. The duty supervisor exhibits 12 thread containers nevertheless that is simply half of the view & there could possibly be an extra 12 containers that are not displayed. The alignment is unquestionably not appropriate for a 16 core half nevertheless I could also be fallacious right here so let’s speak in regards to the metrics we will truly see. The Intel Alder Lake CPU is proven operating with a mean temperature of 86C and peaked at 93C. It isn’t recognized what kind of cooling gear was used however the system was stress-tested for no less than an hour.

As for energy consumption, the Alder Lake chip averaged round 250W energy consumption with a peak of 255W. That is consistent with its 255W PL2 score which we heard of earlier than. Beforehand leaked info confirmed us that the ability demand would improve by 50-100W for Intel’s twelfth Gen Alder Lake Desktop CPUs in comparison with eleventh Gen Rocket Lake chips.

That is the height present so we’re speaking increase clock hundreds (Energy Restrict 4) which has a period of lower than 10ms. The present Core i9-11900K has a PL2(Tier 2) score of 250W and we have now seen early ES variants of Alder Lake CPUs (non-Okay) already that includes PL2 rankings of 228W so we will count on over 250W PL2 rankings for the higher-end SKUs.


  • 10/eleventh Gen: 34A/408W
  • twelfth Gen: 39A/468W (+14.7%)

The Intel Alder Lake Desktop lineup and the Z690 platform are anticipated to launch on the twenty seventh of October & would be the first mainstream shopper platform to make the most of PCIe5.0 and DDR5 applied sciences together with a brand new hybrid structure strategy, one thing that Microsoft has optimized for its Home windows 11 working system.
