Fact Check: Is hertz the same as fps?

Is Hertz the Same as FPS?

The claim in question is whether "hertz" (Hz) is the same as "frames per second" (FPS). This question arises frequently in discussions about video gaming, display technology, and multimedia performance. While both terms relate to frequency, they refer to different concepts in the context of technology.

What We Know

Definition of Hertz (Hz): Hertz is a unit of frequency that measures the number of cycles per second of a periodic phenomenon. In the context of displays, it refers to the refresh rate, which is how many times per second a display updates its image [6][8].
Definition of Frames Per Second (FPS): FPS measures how many unique consecutive images (frames) a graphics system can produce in one second. Higher FPS generally leads to smoother motion in video games and videos [8].
Relationship Between Hz and FPS: While both terms involve frequency, they are not interchangeable. A display with a refresh rate of 60Hz can refresh the image 60 times per second, but if a game runs at 30 FPS, it means only 30 unique frames are displayed during those refresh cycles. Therefore, FPS can be less than or equal to the refresh rate (Hz) of the display [2][8].
Practical Implications: For optimal performance in gaming, the FPS should ideally match or be less than the refresh rate of the monitor. If the FPS exceeds the refresh rate, the additional frames may not be displayed, leading to a phenomenon known as screen tearing [6][8].

Analysis

The sources available provide a mix of definitions and contextual information regarding Hz and FPS.

Source Evaluation:
- Unilumin [2] and Corsair [6] are credible sources in the tech industry, known for their expertise in display technologies. Their explanations clarify the distinction between refresh rate and frame rate, emphasizing that they serve different functions in multimedia experiences.
- How-To Geek [8] is a well-regarded tech website that provides accessible explanations of technology concepts. Their article reinforces the relationship between FPS and Hz, making it clear that while related, they are not the same.
Potential Bias: The sources cited do not appear to have significant conflicts of interest, as they provide educational content rather than promotional material. However, it's essential to consider that companies may present information that favors their products or technologies.
Methodology and Evidence: The articles do not cite empirical studies but rely on established definitions and common knowledge within the tech community. This is typical for discussions on technical terms, but additional quantitative data or studies could enhance the understanding of how these metrics affect user experience.

Conclusion

Verdict: False

The claim that "hertz" (Hz) is the same as "frames per second" (FPS) is false. The evidence clearly indicates that while both terms relate to frequency, they refer to distinct concepts: Hz measures the refresh rate of a display, while FPS measures the number of unique frames produced by a graphics system in one second. The distinction is crucial for understanding how multimedia performance works, particularly in gaming and video playback.

It is important to note that while the sources used in this analysis are credible and provide a solid foundation for understanding the differences between Hz and FPS, they do not include empirical studies to support their claims. This absence of quantitative data means that while the definitions are widely accepted, there may be nuances in specific contexts that are not fully explored.

Readers are encouraged to critically evaluate information and consider the context in which terms like Hz and FPS are used, as well as the implications for their own technology use.
