Prime95 runs indefinitely and only terminates a stress test when it encounters an error and informs the user that the system may be unstable. It tests your computer for stability issues by stressing your CPU to its maximum limit. There are quite a few different computer stress test utilities out there, but Prime 95 – which was a piece of freeware originally designed to find Mersenne prime numbers – is the most widely used and most accurate one. Stress tests are incredibly accurate and nifty when it comes to determining how stable and error-free a computer really is. The only utilities I've ever found that come as close as possible to 100% TDP are Prime95 v26.6 Small FFT's for thermal testing, which is a steady workload, and Asus RealBench for stability testing, which is a fluctuating workload.Īlthough the topic of Prime95 (with and without AVX) was covered, I would like to have seen RealBench included in your test suite, as it's widely accepted as an excellent utility for testing overall system stability, and uses a realistic AVX workload.A CPU stress test is a thorough analysis conducted to measure the stability of a computer either for informative purposes or to determine whether or not it should be overclocked and to what degree it can be overclocked. However, since Intel validates their thermal specifications at a steady 100% TDP, it's most appropriate to select utilities that don't overload or underload the CPU.
This article provides some excellent comparisons. Since most users test their rigs without a sense of scale for power and temperature, they can't compare apples to apples, especially when combined with major variables such as differences in ambient temperature, hardware configurations and software utilities. Otherwise, great work! I was very pleased to read this article!Ģ0741319 said:As the author of the Intel Temperature Guide - I can fully appreciate how much work went into creating this outstanding article, which has been sorely needed!

Nevertheless, our results are very similar. The Intel Temperature Guide differs in its approach toward the topic of processor Core temperatures and cooling with respect to Intel's TDP specifications, and distinguishes between steady workloads for thermal testing versus fluctuating workloads for stability testing. This article provides a perspective and some excellent comparisons.
