In this article, we give you Best Stress Test GPU Tools Free For Personal Use. For Computer builders, testing a Computer thoroughly — from inside and outside — is of paramount value before they finally move to a new PC. That is why, in this article, we bring you the great tools to stress test GPU so you can have a great idea about your machine’s graphics rendering capability. We have been extremely selective about the software and have only discussed those reliable programs and don’t carry a risk of hardware damage. Now having stated that, let’s go ahead and unpack the best programs for GPU stress testing.
Software to Stress Test GPU in 2021
We have introduced 6 programs to stress test GPU, which are mostly free for personal use. Nevertheless, if you want an extended period of loop test, then you may have to buy an advanced edition of the program. Notwithstanding, here are the software programs that will allow you to overclock your GPU and test its stability.
Besides the CPU test, AIDA64 Extreme also allows a GPU stress test known as the GPGPU Benchmark test. It has a system stability test covering the GPU, and you can run a series of graphically intensive tasks to drive the PC to its brink. AIDA64 Extreme deploys a 64 bit multi-threaded stress testing module and utilizes OpenGL API to push the GPU to its maximum capacity.
Having stated that, the best part about AIDA64 Extreme is how user-friendly it is. You’ll get all sorts of information even under heavy stress like power consumption, GPU usage, frequency, temperature, and more. Simply put, if you’re new to this world and want a simple tool to stress test the GPU, then AIDA64 Extreme is a great start.
The next on our list is MSI Kombustor. MSI Kombustor is MSI’s well known tool for stress testing and benchmarking the GPU. It’s particularly designed to push your graphics card to the absolute limit through several intensive simulations and demos. Among other things, MSI Kombustor further measures the thermal performance and tests the stability of the GPU.
To take full benefit of MSI Kombustor, you should use another MSI utility called Afterburner. It’s an overclocking tool by MSI that provides you full control over your graphics cards. You can customize the fan profiles and modify the GPU’s clock frequency and voltage. It will enable you to find the perfect balance between temperature and performance.
As for the Kombustor, it supports all important graphics API– DirectX, OpenGL, and Vulkan — to test GPU’s performance in all environments. Aside from that, MSI Kombustor puts a ridiculous amount of load on the GPU through many advanced tests, including Artifact scanning, PhysX 4 GPU stress test, Depth-of-Field test, Tessellation, Physically based rendering, and more.
In addition, it further leverages Furmark’s highly intensive tests to stress the GPU to its extreme. I would state, if you have a high-end graphics card, then MSI Kombustor is among the best tools to stress test GPU.
3DMark is another famous way to stress test the GPU that also offers a benchmarking score. Similar to Unigine, it further brings several benchmark tests to measure your GPU’s capability. Some of the famous ones are Time Spy, Fire Strike, Tomb Raid, and more.
I find Time Spy the most demanding of all the tests because it takes full benefit of the new DirectX API, for example, asynchronous compute and multi-threading. As a result, 3DMark places a ridiculous amount of load on the GPU to push it to extreme limits. It’s, in fact, very intensive that it also brings the powerful GeForce GTX 1080 Ti to its knees simply after a few cycles of tests.
Aside from that, the tests have advanced graphical-visuals with lighting and shadow effects. All this makes assured the GPU usage goes as high as 100% so that you can find your machine’s capability. And as I stated, 3DMark gives a standard and cross-platform benchmark score, which you can use to measure your GPU’s ranking– irrespective of the graphics card manufacturer, be it Nvidia, AMD, or Intel. So to conclude, 3DMark is an equally great stress testing software for GPU, and you should try it on your machine.
While OCCT is commonly known for stress testing CPU, it can further torture the GPU to its absolute brink. You can utilize OCCT to test the stability of your overclocking parameters like voltage, frequency, and resolution. It deploys OCCT’s variant of the GPU stability test, which is called the furry donut. The graphics rendering engine is very powerful that historically it has blanked out screens of computers powered by a major graphic card. As a result, the test has revealed significant design flaws in the architecture of the GPU chipset.
The great part about OCCT is that it’s not just a stress testing software but also enables you to detect GPU errors and monitor the active readings. You can take the benefit of the GPU: MEMTEST to find errors in the graphic’s card memory. All-in-all, OCCT is a multi-purpose tool to stress test the GPU, and you should give it a try. The single downside is that you don’t get a benchmark score, but that is passable.
Unigine creates 1 of the best gaming engines in the world. Apart from that, it also gives a few gaming tests that can stress test your GPU to no end. A few of the popular tests are Superposition, Valley, and Heaven. You can go with any of the stated tests, but if you want to stress your GPU, go with Superposition.
It’s a pretty demanding test that renders advanced visuals created by the powerful Unigine engine itself. Aside from that, the test includes 900 interactive objects with dynamic-lighting technology and VR module testing. All the while, you can watch GPU usage, FPS count, power supply, cooling system, temperature, and more.
The great part about Unigine and Superposition, in particular, is that it renders an interactive environment that even the most detailed games do not have. And on top of it, you can stress test the graphically intensive environment for a long time to check the GPU stability. Not to mention, Unigine also gives a benchmark score, so you can easily compare your GPU score with other systems around the world.
Having stated that, if you want to stress-test your GPU for more cycles, you can likewise go with Heaven and Valley. They are pretty good and offer a beautiful yet testing environment. To sum-up, Unigine is a complete stress testing tool that includes testing, monitoring, and benchmarking. Therefore just go with Unigine, and you won’t be disappointed for sure.
Many think that FurMark is overkill for stress testing GPU, and rightly so. It places a tremendous load on the GPU to the point it can damage your hardware due to overheating. Nevertheless, you can take its basic test, a standard OpenGL test, to measure GPU’s stability. You can even give a custom preset such as resolution, dynamic background, screen mode, throttle time, and more.
While the tests are highly advanced, you can not monitor many essential metrics with the FurMark application. You’ll have to utilize software like MSI Afterburner utility to keep an eye on GPU’s usage and temperature. To end, go with FurMark if you have the experience and expertise required in stress testing GPU.
Note: Nvidia automatically underclocks its GPU the time you run FurMark. Therefore, if you are testing FurMark on an Nvidia GPU, you’ll not get a proper reading. In that case, it’s recommended to try another tool from this list.
Stress Test GPU with These Tools & Check Stability
So those were our 6 picks for the best GPU stress testing software. Almost all the tools discussed in this list are safe to use, so don’t worry about damaging your GPU. Nevertheless, be slightly cautious while using FurMark as it can drive the GPU nuts if not configured properly. Anyway, if you require more such programs to test various hardware components, then comment below and let us know. We will heed your suggestions.
