Geekbench 6 is a cross-platform benchmark that measures your system's performance with the press of a button. How will your mobile device or desktop computer perform when push comes to crunch? How will it compare to the newest devices on the market?





FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool (also called GPU...

UNIGINE benchmarks can be effectively used to determine the stability of a GPU under extremely stressful conditions, as well as check the cooling system's potential under maximum heat output.




The Phoronix Test Suite carry out automated tests. It is open source. It has access to more than 450 test profiles and over 100 test suites. These tests range from battery power consumption monitoring for mobile devices to multi-threaded ray-tracing benchmarks and span the CPU...



Prime95 is a program that searches for new Mersenne prime numbers. It is commonly used as a stability test for overclocked computers.




GST is a GTK system utility designed to stress and monitor various hardware components like CPU and RAM.

Tyler's Frame Machine is a simple, free, educational, small, cross-platform, and portable tool for testing, benchmarking, calibration, framerate comparison, and demonstration.

Linpack is a benchmark and the most aggressive stress testing software available today. Best used to test stability of overclocked PCs. Linpack tends to crash unstable PCs in a shorter period of time compared to other stress testing applications.

It is possible to use it freely and it is way small compared to PCMark etc.
