Computer Stress Test Software To Test CPU, RAM And GPU

Stress testing is a type of performance testing that validates the highest limit of your computer, device, program, or network with an extreme load.Stress testing will check the behavior of a system, network, or application under an immense load. It also checks whether the system can recover while returning to the normal stage or not.get into pc

The main purpose of stress testing is to check the recoverability of the system, program, device, or network.

There are different types of stress testing 

i.e. Distributed Stress Testing, Application Stress Testing, Transactional Stress Testing, Systemic Stress Testing, and Exploratory Stress Testing.

This article will help you in selecting the right stress testing tool. Tool selection depends on the type of testing that you want to perform like Stress testing for your PC, Stress testing for CPU, Stress testing for RAM, or Stress testing for GPU.


While performing hardware stress testing, we need to monitor different factors like temperature, etc and it varies according to the model design and infrastructure. Coverage of stress testing, as well as the risk, should be considered before it is performed.

If you are performing stress testing on the computer then the focus of stress testing will be on two components, i.e. the CPU and memory.

CPU stress testing is performed to check the CPU’s performance after running it at a full speed completely up to maximum temperature. When CPU stress testing is performed, all the cores of the multi-core system will get used. CPU will get tested with a compatible and justified workload.

GPU stress testing is performed to check its limits by utilizing its full processing power. Stress testing a RAM is the first thing that you should perform if you are facing any of the problems like bluescreen or system reboot.

Different tools use different techniques for checking the performance of the system. For Example, some tools use a 3D scene or some use the prime numbers.

LoadTracer is a tool for stress testing, load testing, and endurance testing. It is used to check the performance of web applications. It is a lightweight application. It works with any browser and technology. It is easy to use and allows you to perform testing without scripting.


  • It has an analyzer for producing graphs and reports.
  • LT Monitor will provide various performance counters for monitoring.
  • The Recorder can record all the interactions between the browser and the server. It generates the script file of that.
  • Using the script, Simulator generates virtual users.


JMeter is an open-source application. Initially, it was designed for testing web applications but now some other test functions are also included. It is used to measure the performance of static and dynamic resources.

It is also used to load test the functional behavior of applications. It is used to load test the server, group of servers, network, etc.


  • It provides the command-line mode to java compatible OS.
  • It offers Test IDE which can record, build, and debug.
  • Facility to replay the test results.
  • It provides an HTML report.
  • Complete portability.
  • Pluggable and Scriptable Samplers.


Like JMeter, Locust is also an open-source tool for load testing. It supports defining user code with Python code. Instead of clunky UI, it provides you the facility to describe your test in Python code.


  • It supports the running of load tests on multiple distributed machines.
  • It is scalable as millions of users can be simulated simultaneously.
  • User behavior can be defined in code.
