You have finally been able to upgrade that old CPU you had in your computer to a modern Ryzen 9 5950X or Core i9-11900K and the change is amazingly noticeable. If you still have the concern to know how much more you could demand from your new toy to make an overclock, you can make one stress test with any of these tools that we analyze to help you.

Besides building a new computer, there are other reasons to stress test your CPU. Many gamers (or crypto miners) will overclock their processor and GPU to get the most out of it.
If you’re going to overpay for a GPU, you can also try to get more value for your money, right? Additionally, companies or schools running high-performance workloads may want to test their systems to see if they can handle the stress of sustained loads.
This can be a valuable resource in making sure your cooling solution is doing its job, as these stress tests literally push your processor to the limit. It’s so important that we have a complete guide on how to check your CPU temperature right here.
Prime95 is one of the best known processor stress tests out there. It was developed by Great Internet Mersenne Prime Search (GIMPS) in which the CPU is used to find large prime numbers.
Although Prime95 is not originally designed to stress test the processor, the stress in using floating point and integer capabilities make it a great way to see what it is capable of.
You can run different “torture tests” depending on what you are trying to emphasize. Small fast Fourier transforms (FFTs) can be a good way to see if there are any problems. Big FFTs really punish your processor, while the combined tests boost RAM usage.
Unlike Prime95, AIDA64 it is not free to use. The cheapest version is AIDA64 Extreme, which will cost you around $ 50 to use on three computers, while the Business and Engineer versions cost $ 200.
Obviously, this tool is geared more towards engineers, IT professionals, and enthusiasts (as indicated by its various download options). Rather than purely stressing the processor like Prime95, it simulates a more realistic workload that a CPU is likely to have.
This is excellent for measuring workstations or servers intended for sustained, high-performance workloads. AIDA64 is an all-in-one diagnostic tool that can be used to view the details of your particular system.
In the System Stability Test, you can choose which component (processor, memory, local disks, or GPU) you want to emphasize. While the test is running, there is a Sensor tab that allows you to see the temperature of each CPU core and the fan speeds.
This can be invaluable to see if your system is being properly cooled and stressed and to realize the proper functioning and performance of the processor and, on the other hand, to avoid possible damage from overheating.
Cinebench is another well-known free reference utility that you may have seen in various reviews. It was created by Maxon, the developer behind Cinema 4D, a 3D modeling software.
Cinebench simulates common tasks within Cinema 4D to measure system performance. Specifically, the main test shows a photorealistic 3D scene and uses algorithms to stress all the processor cores.
The render is approximately 2,000 objects made up of more than 300,000 polygons. The most common version, R23, can run a ten minute thermal throttling test instead of a single run.
This can be useful to see how much you can push on a particular system before it gets too hot. That being said, the single run is still available in the advanced options. The latest version also adds support for Apple’s M1 processor.
