FurMark and 3DMark answer different GPU questions. Use 3DMark when you need a named, repeatable graphics workload and a score you can compare with similar systems. Use FurMark when you need an unusually heavy GPU load to observe heat, power behavior, or basic stability. Neither tool replaces the other, and their scores must not be put on a shared scale.
The practical choice is simple: select a matching 3DMark test for performance comparisons, then use a cautious stress run when you need to investigate cooling or stability after a build, upgrade, or overclock. A game-specific test suite is still needed to judge how a graphics card behaves in your actual games.

3DMark supplies several named graphics workloads built around different graphics APIs, rendering resolutions, and target hardware. A result belongs to one particular test, such as Time Spy or Speed Way, so you can compare it with systems that ran the same workload under comparable conditions. UL’s overview also lets the application recommend a suitable benchmark and compare results with systems using the same CPU and GPU combination.
FurMark instead applies a deliberately heavy GPU load. It is useful when you want to observe power draw, temperatures, fan behavior, clock behavior, artifacts, hangs, or shutdowns under an extreme workload. Tom’s Hardware characterizes it as less about predicting game performance and more about stress testing and power use.
That is why a FurMark result cannot be translated into a 3DMark score, a game frame rate, or a percentage advantage over another graphics card. The workloads, scoring systems, and purposes are different.
Which benchmark should I use for my goal?
Choose 3DMark for a fair performance comparison and FurMark for a heavy-load stability or thermal check. Use this decision guide before launching either program.
| Your question | Use | What to record or watch |
|---|---|---|
| How does this GPU compare with similar systems? | 3DMark | The exact test, settings, CPU, GPU, operating system, and driver version |
| Does my system complete a demanding graphics workload after a build or upgrade? | 3DMark stress test, with a separate heavy-load check if needed | Crashes, hangs, visual artifacts, overheating, or shutdowns |
| How hard does the GPU run in an extreme load? | FurMark | Temperature, power behavior, clocks, fan response, artifacts, and whether the system remains stable |
| What frame rate should I expect in a particular game? | Neither alone | Use a test of that game, with its own settings and resolution |
A stress test can reveal a problem without identifying the failed component. Treat an error as a reason to investigate cooling, power delivery, drivers, settings, or hardware rather than as proof that one specific part is defective.
Which 3DMark test should I choose?
Match the named test to the graphics API, hardware class, and workload you want to represent. UL’s selection guide lists those target characteristics, and the application can recommend a suitable test; for a published comparison, still state the exact test and settings.

Time Spy for DirectX 12 gaming PCs
Time Spy is a DirectX 12 test for Windows gaming PCs. It is an appropriate choice when your comparison is meant to represent a conventional DirectX 12 gaming workload and the systems being compared support that test.

Speed Way for DirectX 12 Ultimate ray tracing
Speed Way is a DirectX 12 Ultimate ray-tracing benchmark. Choose it when ray-traced rendering is the question, rather than using it as a generic substitute for every other 3DMark result. UL specifies a 2560 × 1440 rendering resolution for Speed Way.
Steel Nomad for high-end, non-ray-traced graphics
Steel Nomad is described by UL as a high-end, non-ray-traced test. Its specified rendering resolution is 3840 × 2160. That makes the test more relevant when you want a demanding rasterization workload for powerful current hardware, not a ray-tracing comparison.
Fire Strike and other named workloads
Fire Strike is another distinct 3DMark workload; UL’s technical material gives 1920 × 1080 as its rendering resolution. Do not treat a Fire Strike score as interchangeable with Time Spy, Speed Way, Steel Nomad, or any other test.
The desktop resolution shown by your monitor is not necessarily the test’s rendering resolution. UL explains that 3DMark tests render at fixed resolutions and then scale the output to the desktop; that scaling has a negligible effect on the score. CPU or physics tests may use lower rendering resolutions so GPU performance does not become the limiting factor.

Run the same named test with the same settings, then report enough system context for someone to identify the comparison.

- Name the exact test. Write “3DMark Time Spy,” “Speed Way,” “Steel Nomad,” or the specific workload used, rather than saying only “my 3DMark score.”
- Keep the settings aligned. Use the same test mode, resolution or preset where applicable, and feature configuration. A result from a different mode is a different comparison.
- Identify the hardware. Include the graphics-card model, CPU, memory configuration when relevant, and any overclock or altered power setting.
- Record software context. Include the operating system and relevant graphics-driver version. UL specifically recommends including the operating system, system hardware, and relevant driver versions when reporting a score.
- Compare like with like. Use results from similar CPU/GPU combinations and the same named test. A higher number in one test does not establish a ranking in another.
A useful report has this form: Test name and version or mode; score; GPU; CPU; operating system; driver; resolution or preset; and any overclock or unusual setting. If one of those fields is unknown, say so instead of implying that the result is fully comparable.
There is no single “3DMark score.” Every score is attached to a particular workload.
What does a FurMark result actually tell me?
It tells you how the GPU and system behave under FurMark’s unusually demanding load. It does not tell you how many frames a game will render or how the card ranks in a 3DMark comparison.
Recommended Free Tools
During a FurMark run, watch the available system telemetry: GPU temperature, power behavior, clocks, fan response, and signs of visual corruption. The useful outcome may be an observation rather than a score—for example, that the system reaches a high load without artifacts, or that it overheats and shuts down.
Modern GPUs can include protections against extreme loads, as Tom’s Hardware notes. Those protections do not turn the workload into a game-performance test, and they do not guarantee that every system will remain within a safe operating range under every configuration.
Do not publish a universal “safe FurMark temperature” from this comparison. Safe limits vary by GPU design, firmware, ambient conditions, cooling, and manufacturer guidance, and the supplied evidence does not establish one threshold. Stop a run if the system overheats, becomes unstable, or shuts down, then investigate rather than repeatedly forcing the same condition.

How should I use 3DMark stress tests after a build or upgrade?
Use a 3DMark stress test as one reliability check after building a PC, replacing a graphics card, or changing clock settings—not as proof that the whole system is healthy. UL identifies crashes, hangs, and visual artifacts as signs of a possible stability issue, while overheating and shutdowns can indicate inadequate cooling.
- Establish a baseline. Run a suitable 3DMark workload at known settings and save the result with the system and driver details.
- Apply the change you need to check. This could be a new graphics card, a completed build, or an overclock. Record what changed so you can reverse it.
- Run the relevant 3DMark stress test. Observe whether the workload completes consistently and whether the software reports instability.
- Monitor the system while it runs. Watch telemetry and the display for artifacts. If the machine overheats or shuts down, stop and allow it to cool before troubleshooting.
- Change one variable at a time. Return to stock settings, check cooling and power connections, and review drivers before drawing conclusions about the hardware.
- Use a second workload when necessary. A system can pass one synthetic workload and still fail in a particular game or application, so follow up with the software that matters to you.
A completed stress run is evidence about that run. It is not a diagnosis of the exact failed component, nor a guarantee that every future workload will be stable.
Can FurMark replace a gaming benchmark?
No. FurMark should not be used alone to predict game frame rates or choose between graphics cards for a particular title. Its load is intentionally unlike a normal game in important ways, and its purpose is to expose behavior under stress.
For gaming decisions, use a benchmark or repeatable in-game scene that matches the API, resolution, quality settings, and ray-tracing features you actually care about. Then keep FurMark in a separate role: checking how the system handles a severe thermal and power load.
3DMark sits between those uses. Its named workloads are repeatable and useful for broad graphics comparisons, but even a 3DMark result is not a substitute for testing the games you play. Treat it as a controlled reference point, not a universal forecast.

- Comparing different 3DMark tests. Time Spy, Speed Way, Steel Nomad, and Fire Strike have different APIs, rendering targets, and workloads. Their scores are not on one scale.
- Calling a FurMark number a performance score. A FurMark result describes that stress workload and its observed behavior, not expected game performance.
- Reporting only the number. Without the test name, hardware, operating system, driver, and settings, readers cannot judge whether the comparison is meaningful.
- Confusing desktop resolution with render resolution. 3DMark’s fixed internal resolution may differ from the display mode shown by Windows.
- Treating one pass as proof of health. Stability evidence is workload-specific. A pass reduces uncertainty but does not rule out every driver, cooling, power, or game-specific problem.
- Repeating an overheating run. If a system overheats or shuts down, stop, investigate cooling and configuration, and avoid treating repeated forced shutdowns as a normal benchmark procedure.
Which tool should you install first?
Install or access 3DMark first if your immediate goal is a comparable performance baseline; start with FurMark only when the immediate question is thermal or stress behavior. This order keeps the result tied to a clear purpose.
For a new build or GPU upgrade, begin by documenting the hardware and driver context, select the appropriate 3DMark workload, and save the test-specific result. If you then need to investigate cooling or stability, run a separate stress check while monitoring telemetry. For an overclock, use the same sequence after each meaningful change so you know which configuration produced the behavior.
If your only question is whether a card will run a particular game, neither utility is sufficient by itself. Use a repeatable game test for the final decision, and treat the synthetic tools as supporting evidence.
How we picked the recommendation
The recommendation follows each tool’s documented purpose and the meaning of its output: 3DMark’s named, test-specific workloads and comparison guidance from UL; FurMark’s heavy-load, power, and stress-testing role described by Tom’s Hardware; and UL’s warnings that stress-test failures are indicators for further investigation rather than automatic diagnoses. No FurMark-versus-3DMark percentage or universal threshold is claimed because the supplied evidence does not establish one.
Bottom line: use both, but never confuse their jobs
Use 3DMark when you need a repeatable graphics-performance reference, and identify the exact test because there is no overall 3DMark score. Use FurMark when you need to observe behavior under a deliberately heavy GPU load, especially power, thermals, and basic stability. Compare only like-for-like 3DMark results, treat stress failures as clues to investigate, and finish with the game or application workload that matters to you.
Frequently Asked Questions
Can FurMark damage a graphics card?
FurMark is intentionally demanding, and modern GPUs may use protections against extreme loads, but no stress tool makes every configuration risk-free. Monitor the system and stop if it overheats, becomes unstable, or shuts down; do not repeatedly force a failing run.
How long should I run a GPU stress test?
There is no universal duration established by the supplied guidance. Use a planned run long enough to observe the behavior you are investigating, monitor it continuously, and stop immediately for overheating, artifacts, instability, or shutdown rather than chasing a fixed time target.
Why can a 3DMark pass but a game still crash?
A benchmark exercises one defined workload, while a game may use different shaders, APIs, memory patterns, or settings. A pass narrows the investigation but does not rule out a game-specific driver, configuration, cooling, or stability problem; test the affected game separately.
Should I benchmark before or after changing an overclock?
Capture a baseline at known settings first, then test the changed configuration and record exactly what was altered. If the result becomes unstable, return to the last known-good settings and change one variable at a time while checking cooling, power connections, and drivers.
