It deploys OCCT’s version of the GPU stability test which is called the furry donut. You can use OCCT to test the stability of your overclocking parameters like voltage, frequency, and resolution. While OCCT is popularly known for stress testing CPU, it can also torture the GPU to its absolute brink. I would say, if you have a high-end graphics card then MSI Kombustor is among the best tools to stress test GPU. In addition, it also leverages Furmark’s highly intensive tests to stress the GPU to its extreme. Apart from that, MSI Kombustor puts a ridiculous amount of load on the GPU through many advanced tests which include Artifact scanning, PhysX 4 GPU stress test, Tessellation, Depth-of-Field test, Physically based rendering, and more. It will allow you to find the perfect balance between performance and temperature.Īs for the Kombustor, it supports all major graphics API– DirectX, OpenGL, and Vulkan - to test GPU’s performance in all environments. You can customize the fan profiles and adjust the GPU’s clock frequency and voltage. It’s an overclocking tool by MSI that gives you full control over your graphics cards.

To take full advantage of MSI Kombustor, you should use another MSI utility called Afterburner. Among other things, MSI Kombustor also measures the thermal performance and tests the stability of the GPU. It’s specially designed to push your graphics card to the absolute limit through several intensive simulations and demos. MSI Kombustor is MSI’s well-known tool for stress testing and benchmarking the GPU. In that case, it’s advised to try another tool from this list. So, if you are testing FurMark on an Nvidia GPU, you will not get a proper reading. Note: Nvidia automatically underclocks its GPU the moment you run FurMark. To conclude, go with FurMark if you have the experience and expertise required in stress testing GPU. You will have to use a software like MSI Afterburner utility to keep an eye on GPU’s usage and temperature. While the tests are highly advanced, you can’t monitor many essential metrics with the FurMark application. It’s in fact so intensive that it brings even the powerful GeForce GTX 1080 Ti to its knees just after a few cycles of tests. As a result, 3DMark puts a ridiculous amount of load on the GPU to push it to extreme limits. Of all the tests, I find Time Spy the most demanding because it takes full advantage of the new DirectX API such as asynchronous compute and multi-threading. Some of the popular ones are Time Spy, Fire Strike, Tomb Raid, and more. Similar to Unigine, it also brings a number of benchmark tests to measure your GPU’s capability. 3DMarkģDMark is another popular way to stress test the GPU that also offers a benchmarking score. So just go with Unigine and you won’t be disappointed for sure.Ĭheck Out Unigine (Free, Starts at $19.95 for Advanced Editions) 2.

To sum up, Unigine is a complete stress testing tool that includes testing, monitoring and also benchmarking. They are quite good and offer a beautiful yet testing environment. Having said that, if you want to stress-test your GPU for more cycles, you can also go with Heaven and Valley. Not to mention, Unigine also offers a benchmark score so you can easily compare your GPU score with other systems around the world. And on top of it, you can stress-test the graphically intensive environment for an extended time to check the GPU stability. ( stress or stress-ng can also do that if you either installed, if you use a simple CPU-stress method.The best part about Unigine and Superposition, in particular, is that it renders an interactive environment that even the most detailed games don’t have. Awk is a good way to write a long-running loop that's CPU bound without generating a lot of memory traffic or system calls, or using any significant amount of memory or polluting caches so it slows down other cores a minimal amount.
