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. 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!

To run Intel® PDT from preset configuration go to tools > config > preset. 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.

It's compatible with both Intel and Apple silicon architectures so it's ready for all current and future Mac models.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! We wanted to make a simple to use utility that was useful to the Mac community at large, for everyone to use. No purchase, no in-app purchase and no ads. There's no cost for Endurance: CPU Stress Test. In addition to stress testing, it also shows the current CPU load, battery level, time elapsed for the test, along with all data logged to a CSV file. More so, if you are using it on your personal computer then the program is completely free. In fact, it's the perfect companion to TG Pro, which displays all internal temperatures such as the CPU, GPU, battery, etc along with fan speed and control. All in all, if you are looking to stress test your CPU for checking hardware errors then OCCT is a one-stop solution for you. It's the easiest app for benchmarking how the Mac reacts to increased thermal pressure, along with the battery life. It's easy to customize from between 1-64 threads. Need to test at 50% CPU usage? Choose half the number of threads compared to cores and click run.
It will keep the CPU busy from a low percentage or all the way to 100% for as long as it's needed. A stable CPU is one that can withstand the demands placed upon it by a stress test. Setting this value to Maximum causes the thread to run continuously. Each thread can be started, paused or stopped independently and can be configured with the following parameters: Activity Level This can be Low, Medium, Busy or Maximum which controls how long the thread sleepss between cycles. Instead of opening up Terminal, typing in cryptic commands, or trying to find outdated apps to test the CPU, it's as simple as choosing the number of threads to run and clicking start. The program can display information about all of your computers software and hardware and can diagnose and stress the processor, memory, disks and GPU. To accomplish this, a program known as a CPU stress testing tool is used. CpuStres CpuStres is a utility that can be used to simulate CPU activity by running up to 64 threads in a tight loop.
Endurance: CPU Stress Test solves the problem of having a way to test the thermal limits or battery life of a Mac.
