100°C and throttling withen seconds (less than one minute)

[jjp3]

I have i7-12800hx with locked multiplier by the manufacture.

The active cores clocks should be @4.2GHz with 8 active p-cores. Please see the attached picture 1.

But I stress the CPU, whiten seconds it will reach throttling temperature, 14 seconds to reach 100°C and the throttling speed will be 3.7GHz. Please see the attached video

My understanding is when 8 active p-cores the speed should be 4.2GHz and not 3.7GHz and the temperature should exceed even 90°C

The laptop is still in warranty and I want to replace the laptop, so is it a faulty CPU or is this normal behavior.

Thanks

jjp3, Thank you for posting in the Intel® Communities Support.

We will be more than glad to assist you with this matter. 

In reference to this scenario, first, it is important to mention that we always recommend to use the computer at stock configurations with the default BIOS settings. Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. Product warranties may not apply if the processor is operated beyond its specifications. 

In regards to your question, with 8 active p-cores, yes, the processor could reach up to 4.80 GHz, but that does not necessarily mean that the clock speed will be stuck at that value, the clock speed fluctuates depending on the tasks performed at a specific moment, the applications being used and the resources utilized by the operating system. Based on that, it is normal behavior for you to see 3.7GHz when using your machine. Also, it is expected for the processor to get overheated while you are doing a stress test since you are forcing the unit to run at its maximum capacity. The T-junction for this processor is 100°C, any temperature result lower or equal to that value is considered normal and expected for the Intel® Core™ i7-12800HX:

In order to rule out a possible hardware issue with the processor, please install and run the Intel® Processor Diagnostic Tool, it does an overall test on the unit and if it passes the test it means it is working properly:

In the following link, you will find "My Laptop Seems to Be Overheating" with additional details on this subject:

https://www.intel.com/content/www/us/en/support/articles/000060293/processors.html

We also recommend to get in contact with the manufacturer of the computer to make sure the latest BIOS version is currently installed in your device or to gather the instructions on how to update it.

Once you get the chance, please let us know the results of the test and if possible the model of the laptop.

Any questions, please let me know.

1- I am using the default settings, and the overclocking are locked I can't even change anything.

2- The speed for 8 active cores is 4.2GHz and not 4.8 GHz.

3- My question is normal to get 100°C within seconds.

4- Is thermal throttling normal within seconds

More info: I am getting 15% less benchmark points using Cinebench23 than the reported results for the same CPU in https://www.notebookcheck.net/Intel-Core-i7-12800HX-Processor-Benchmarks-and-Specs.618781.0.html

notebookcheck.net reported 22456 points for 12800hx, while I am getting only19288 points. that means almost 15% decrease in performance

More. I have always had Intel CPUs and I never once get a temperature more than 90°C, this the first time I am getting 100°C and thermal throttling.

[Alberto_R_Intel]

jjp3, Thank you very much for providing that information.

In reference to your inquiries about whether it is normal to get 100°C and thermal throttling within seconds, I will do further research on this subject to confirm those details. As soon as I get any updates, I will post all the details on this thread.

Hello jjp3, I just received an update on this matter.

After revving this case, in reference to your first inquiry, is it normal to get 100°C within seconds? Yes, it is normal, please verify the information shown in the link below under the: "Is it bad if my processor frequently approaches or reaches its maximum temperature? tab:

https://www.intel.com/content/www/us/en/support/articles/000005597/processors.html

Regarding your other question, is thermal throttling normal within seconds? Yes, it is possible as well, please visit the following link to check further details about this subject: 

https://www.intel.com/content/www/us/en/support/articles/000088048/processors.html

Additionally, it is important to mention that when using third-party tools such as Cinebench23 and notebookcheck.net, the outcomes might not be that accurate and there could be misreadings on the results. That is why we recommend to use the Intel® Processor Diagnostic Tool, which is our official tool and the one we rely on.

As an option, you can also install and run the Intel® Extreme Tuning Utility (Intel® XTU) which is used to overclock, monitor, and stress a system since we cannot validate, or ensure third-party reports: 

https://www.intel.com/content/www/us/en/download/17881/intel-extreme-tuning-utility-intel-xtu.html

Still, for this scenario, based on the fact that the laptop is still under warranty, if you suspect that it might have overheating issues, we suggest to get in contact directly with the manufacturer of your computer for additional debugging since the configuration and customization of your laptop will depend on OEM (Original Equipment Manufacturer) designs.

Thanks for your reply, but the links you refer state to the contrary.

Is it bad if my processor frequently approaches or reaches its maximum temperature?

Not necessarily. Many Intel® processors make use of Intel® Turbo Boost Technology, which allows them to operate at very high frequency for a short amount of time. When the processor is operating at or near its maximum frequency it's possible for the temperature to climb very rapidly and quickly reach its maximum temperature. In sustained workloads, it's possible the processor will operate at or near its maximum temperature limit. Being at maximum temperature while running a workload isn't necessarily cause for concern. Intel processors constantly monitor their temperature and can very rapidly adjust their frequency and power consumption to prevent overheating and damage.

"Not necessarily" Means it is not 100% OK

"When the processor is operating at or near its maximum frequency it's possible for the temperature to climb very rapidly and quickly reach its maximum temperature"  possible, not a sure thing.

"In sustained workloads, it's possible the processor will operate at or near its maximum temperature limit" Means not within seconds, it has to be sustained.

I checked this youtube video https://www.youtube.com/watch?v=KV6h53y3AV0 and the P-cores didn't exceed 90°C and the E-Cores didn't exceed 70°C even when overclocking. My CPU will reach 100°C within seconds without even overclocking

Again thanks for the reply.

jjp3, You are very welcome, thank you very much for your response and for sharing those comments.

Yes, what those statements mean is that it is not necessarily a bad thing for the processor to reach its maximum temperature because the Intel® Turbo Boost Technology feature allows them to operate at very high frequency, and when that happens it's possible for the temperature to climb very rapidly and quickly reach its maximum temperature.

And you are correct, although it says it has to be sustained workloads not within seconds, that also does not indicate for sure that the processor is defective, even though is not very common for the processor to act like that. Especially, if no tasks are being performed or applications running constantly. Based on that, we always advise using the Intel® Processor Diagnostic Tool, to rule out that possibility.

Regarding the YouTube video, keep in mind that every computer is different, meaning that the performance can be different as well, even though the computers being used/compared have similar or equal specifications, due to the fact that the configuration for every system is always different.

For that reason, at this point, from our side, the best suggestion we can provide will be to get in contact directly with the manufacturer of the computer as soon as possible to report this situation. They did the integration of all the parts and this behavior could be related to a different component like HDD, memory RAM, or even the motherboard itself. They also provide the warranty for all the components, they might be able to reproduce this case using the same exact machine you are working with, to do a physical inspection of the computer if needed, to provide a fix for it, further suggestions or technical assistance and ultimately to replace the laptop under their warranty policies. So, at this moment, to get in contact directly with them will be the best thing to do for this specific scenario.
