As title: is that tool really realiable in any sort?

Official link: https://www.intel.com/content/www/us/en/download/15951/intel-processor-diagnostic-tool.html

I never seen anyone failing it even with an unstable\failing Raptor Lake, so I am really wondering if someone actually failed it as an element to determine if its CPU was failing or not.

Best regards.

Sorry for my bad English
Is my 5600g is really degraded? And how much i can sell it? It requires to oc to boot in windows after that it will freeze and restart for an hr or more while browsing or gaming and sometimes idle The b450 pro a ii asus board gave the cpu to much voltage at auto 1.45to 1.50 while im overclock and used it daily

I have an Intel Core i5-14600KF paired with a be quiet! Pure Rock Pro 3 dual-fan tower cooler, but I’m still experiencing high CPU temperatures and a lower-than-expected Cinebench score.
I installed the new cooler using the thermal paste supplied with it. Both fans are working, the cooler appears to be mounted correctly, and my case has five fans providing airflow.
Despite upgrading to a significantly larger cooler, my Cinebench score has not improved. In fact, it dropped slightly from 4,846 to 4,765 points. The CPU still reaches temperatures close to 100°C and appears to be thermally throttling under a multi-core workload.
I’m trying to understand why the performance is lower than expected and why the Pure Rock Pro 3 struggles to keep the i5-14600KF cooler at around 180 W of power consumption.

Upgrading from a AMD Ryzen 7 5800X to a Intel Core Ultra 7 Desktop Processor 265; is this an upgrade? downgrade? sidegrade?

My 5600X3D seems to be idling around 55-60C (1-3% usage) and maxing out around 90-91C in stress tests.

Are either of these too high? Should I repaste? (I did have to pull the cooler back up twice before actually screwing it in but I used plenty of paste)

Specs:

-3 intake 4 exhaust fans (TL C12C S)

-Thermalright Burst Assassin 120 SE

-80-81F room temperature

I have heard that they r same speed but when boost 9850 is faster but honestly I won’t boost I want the cpu to last for long time as much as possible and I will use it with 5080 and 32 ram, and I want to play apex legends 300 fps solid on 2k also while streaming in twitch, so is still worth it to get the 9850x3d? Pls advice
