The words CPU comparison in google leads to many.

My go to for years has been Passmark, which several of the above reference. I also like the charts that CPU-Z has but it is probably a stutter step above the User Benchmark crap.

To a much lesser degree, I like to check reviews and comparisons on places like YT. It is super important to find a reviewer that is being up front about what is and isn't turned on alongside the actual hardware being used. A lot of those folks are also paid or given concessions to review a product in a positive light. If you can make it through awake Steve at Gamers Nexus is possibly the most honest reviewer I am aware of.

If we knew what task(s) you wanted the CPU for we might be better able to answer that question.
For example, a review of a particular CPU might have the most comprehensive comparisons for that CPU, and all the CPUs used for baseline.

Passmark
cpu-z bench

For gaming, look at the single thread performance,
For multithreaded apps look at the total ratings.

Thanks all.

I built a big desktop PC with i9-9900K few years ago. Now I want a portable mini-PC/laptop that can perform at least as fast as that one. Silence is very important. Am I correct that most modern CPU outperform the i9-9900K? From some benchmarks, it seems to be the case. Main application is 3D CAD (mainly single-core). No gaming on mini-PC or laptop.

The problem is that anything that outperforms a 9900K probably won't be silent if it is a mini-pc.

Run the cpu-Z bench on your i9-9900K with 16 processing threads.
Look at the single thread score. You should see about 640:

Most strong processors have many
processing threads, and that is what generates heat and the consequent noise to cool it.

The other common performance measure is passmark.
The single thread score for a i9-9900K is about 2970.

A modern 15th gen ultra 235 with 6 performance cores and 8 efficient cores has a single core passmark rating of 4491.
It comes with a stock cooler that is relatively quiet under full load.
Such would be suitable for a mini system.

More expensive versions get you more cores, but the single thread performance does not improve as much.

If the CPU have the same TDP, does that mean they would generate the same amount of heat/noise if put inside the same system running the same applications?

Core Ultra 5 225H, cTDP 40W
Core Ultra 5 235H w/vPro, cTDP 40W
Core Ultra 7, 255H, cTDP 40W
Core Ultra 7, 265H w/vPro, cTDP 40W

Heat? Generally yes - assuming some caveats are also the same: whatever the bios and OS power/performance settings are, whether out of the box, or personalized.


Noise? No. There can, and will be multiple laptop models with [select desired CPU], but the deciding factor is the fans(and the rest of the cooling solution), and will not be equal between all models.
Examples: Some models may not provide enough passive ventilation, which would allow the end user(You) to run lower fan curves to lower the noise to your comfort. Others may have powerful, high rpm fans that offer plenty of cooling... but probably get too audible for you to make the most of them, and once personally tuned, the hardware likely runs hot anyway.

This is kind of like one of those you can only choose two jokes -
Quiet
Fast/powerful
Mini/SFF

You have many choices in CPUs from both AMD and Intel. One of your important ones is not the CPU, but the cooling. Whether you go with a small AiO, or some kind of low-profile HS+F setup, quality does matter. The larger the fan, the quieter it generally is, because it runs at a slower RPM to push the same volume of air as a smaller fan.

As an example, this is one of the gold standards for low profile, but great cooling

And since the primary use is CAD, that generally means a potent graphics card. Not SFF friendly.

There are some half height ones that may work, but options are limited, even more so than CPU cooler choices.

Edit - if OP isn't in a rush, there are rumors of a socketable strix halo. An APU like that may be good enough. 'course, they are just rumors, currently.
