[SOLVED] Does Xeon E-2175M generate less heat than i7-8850H?

[modeonoff]

Hi, I bought a Lenovo X1E with i7-8850H but it has noise issue. If everything is the same, does laptop with Xeon E-2176M generate less heat? Is it true that the Xeon E-2175M is more effectient than the i7-8850H?

Judging by their specs, they will produce nearly the same amounts of heat:

https://ark.intel.com/products/134867/Intel-Xeon-E-2176M-Processor-12M-Cache-up-to-4-40-GHz-

In fact, the Xeon could actually be a bit hotter as a result of its small increase in base/boost speeds.

Thanks. I considered to exchange my X1E with 8850H to one with i5-8400H but from what I read in other forums, even users with i5-8400H have fan noise issue. I also read that P1 with P1000/P2000 GPU also have fan noise issue. So, if I want a silent or almost silent machine, I have to stay away from P1 and X1E and perhaps also laptops with an H at the end of the CPU?

Based on what other users mentioned, it seems that the X1E and perhaps also P1 have fans charactistics like this: 1) suddenly fans kick in for no reason even when idling or the user is doing light work like browsing the web or doing office productivity work. 2) in my case even at CPU load of about 1%, fans suddenly kicked in and get noisy. 3) Usually either fans don't spin or spin at about 2500 rpm to the point of annoying especially when working in a quiet place.

I have a similar rig, a Dell Precision 7520, and it is nearly silent, except when under a heavy processing load. Is there a firmware update available for the Lenovo? If so, that could potentially help with the fan settings.

I already updated to the two latest BIOS but it does not help. Actually the situation seems to be worse with the latest BIOS.

I think we are going to merge your two threads. It is the same issue.

MERGED QUESTION
Question from modeonoff : "Thermal of NVIDIA Quadro P1000, P2000 and 1050 Ti Q-Max 4GB"

Hi, I bought a Lenovo X1E with 1050 Ti Q-Max GPU but it has noise issue. If everything is the same, does laptop with P1000 or P2000 GPU generate less heat than the 1050 Ti Q-Max GPU?

A quick scan of the specs for these devices would suggest that the 1050 and P1000 will perform similarly in terms of performance and heat. The P2000 would run hotter than both of the others.

Since you have asked about your new rig's CPU and GPU, have you contacted Lenovo about the noise levels?

Thanks. I posted on their forum but they have no comment.

Might be worth a phone call or on-line chat.

The fans kick in for sure when I play 4K youtube videos in full screen on an external 4K TV. I guess since the LCD of the laptop is 4K, this might push the GPU harder since it has to drive two 4K displays. Do you think a configuration with FHD screen could be less noisy?

Driving 4k content onto a 4k display is a lot of processing for a laptop cooling ecosystem because of the processing load on manipulating all those pixels. How does the system perform (noise-wise) at lower display resolutions?

Don't know how the system performed at lower display resolutions. Can't test it since I returned it. I am considering to get a P1 or X1E (which from your replies does not seem to be better in terms of quieter), T480, T480s, X1C6 or X1 Yoga.

I have a 2 year old Lenovo E560 that is rock solid and VERY quiet. Different class machine than what you are looking at, but an indicator that they make quiet rigs.
