3DMark is one of the most popular benchmarking tools to tax your graphics card or the entire build. It has a very friendly interface which allows you to compare and test the performance of different hardware inside your PC.

This tool comes up with several benchmark tests to evaluate your build’s performance in different workloads like content creation, basic computing, and gaming.

You can run complex graphical scenarios to stress test your card. Among some of them are the Time Spy and Fire Strike benchmarks that test the patience of the most powerful graphics cards on the market.

At the end of each test, you’ll get an overall score which you can then use to compare with other benchmark scores across the platform.

3DMark also provides in-depth information about your graphics which you’ll hardly find from the manufacturer.

This tool supports DirectX 11 & 12 along with added support for ray-tracing and DLSS. In this way, you can quickly know how your graphics card will perform when you turn on the ray-tracing and DLSS at the same time.

Whether you’re a gamer or enthusiast, 3D Mark gives you an in-depth look at every aspect of your graphics card. This tool allows you to measure your GPU performance from every angle.

FurMark: Best for Extreme Testing

When it comes to taxing your GPU with 100% workloads, there’s no better tool than the FurMark. I personally recommend this tool to professionals or users who often overclock their graphics cards.

For beginners, I strongly recommend sticking with the classic OpenGL test to gauge the performance of their graphics card. So, if you have an entry-level or mid-range graphics card, then you can run the OpenGL test to gauge the performance.

For high-end graphics cards, FurMark simulates a series of intense graphical tests, some of those tests include a full-screen antialiased 3D graphics test and a GPGPU test that involves OpenCL to stress test to its limits.

Just like the 3DMark, the FurMark also provides a deeper look at the temperatures, power consumption, frame rates, voltage, clock speed, and other useful factors. All of this information can be used to identify any thermal or bottlenecking issues.

FurMark also gives you a detailed report on issues like GPU freezes, crashes, or artifacts. So, if you are a hardcore gamer, overclocker, or hardware tester, FurMark is a great tool to get valuable insights about your card.

You can use this tool to stress test any Nvidia, AMD, or Intel video card. However, keep in mind that Nvidia underclocks their cards for FurMark to avoid any physical damage as a result of overheating. So you may encounter lower scores if you tax an Nvidia card with FurMark.

Some benchmarking tools are designed for testing gaming performance, and Unigine Superposition is one of them. To be honest, this is the tool I used to test the Nvidia RTX 3070 Ti graphics card and it gave me a really tough time with that upper mid-range chip.

Well, you can also use the simple Unigine benchmark tool to stress test your card, but I’ll recommend going with the Superposition version. This tool is designed to measure the synthetic and real-world scenarios build by a graphics card.

If somehow, you get bored with the Superposition environment, you can try the Heaven and Valley simulation which are super complex 3D environments to render for a graphics card. Unigine has added 900 objects which include dynamic lighting and VR modules.

All of this results in a very complex gaming environment that you’ll even not find in the most advanced AAA games of the time. This means that the Unigine Superposition will stress test your GPU like no other benchmarking tool on the list.

Unigine Superposition allows you to monitor all the important measures like temperature, voltage, power consumption, average frame rates, etc.

Moreover, you can compare your scores with other Unigine Superposition users across the platform. It’s a complete benchmarking and monitoring tool for your graphics card.

V-Ray 5

This is another popular platform for benchmarking your graphics card. V-Ray 5 includes GPU-accelerated path tracing, adaptive image sampling, and unbiased light sampling to simulate and render stunning visuals.

The V-Ray 5 is free to use tool which is used by professionals for creating 3D graphical environments. The tool is not as advanced as the 3DMark and FurMark, but it still offers valuable insights about your card.

The tool is incredibly fast and easy to use. You can also build your own complex 3D environments within the tool. I don’t recommend this tool for beginners, but if you have a little bit of knowledge of V-Ray Sketchup, then this is the right tool to with.

MSI Kombustor

FAQs

Can stress testing damage a graphics card?

No, stress testing cannot damage a graphics card unless you are doing it within a safe temperature limit and your graphics card has enough cooling on it. Make sure you run stress on a graphics card that comes with a better cooling solution. Watch out for the maximum temperature and make sure that it does not climb over 95° C.

How long should I run a GPU stress test?

I personally run a test for one hour or so. You can run the tests for more than one hour, but this can lead to overheating issues, which ultimately can damage your graphics card if there’s no proper cooling on it.
