Refresh Rate vs FPS: What’s the Difference? Understanding Hz and FPS

You'll commonly see monitors advertised as 60Hz, 120Hz, 144Hz, 165Hz, 240Hz, and even higher.

At the same time, games can run at 60 FPS, 120 FPS, 144 FPS, 240 FPS, and even higher.

But what exactly is the difference between refresh rate and FPS?

Does a 240Hz monitor mean you'll automatically get 240 FPS?

And what happens when your PC produces more FPS than your monitor can refresh?

This guide explains how refresh rate and FPS work together, what the different combinations mean, and how to choose the right refresh rate for your PC.

What Is FPS?

FPS stands for Frames Per Second.

It tells you how many individual frames your PC is rendering every second.

For example:

  • 60 FPS → 60 frames per second
  • 120 FPS → 120 frames per second
  • 144 FPS → 144 frames per second
  • 240 FPS → 240 frames per second

FPS is mainly affected by your CPU, GPU, game, resolution, and graphics settings.

A more powerful gaming PC can generally produce higher FPS, although performance depends on the game you're playing.

Think of FPS as the number of images your PC is creating every second.

The more frames your PC produces, the more frequently the image can change.

What Is Refresh Rate?

Refresh rate is measured in Hertz (Hz) and tells you how many times your monitor can refresh the image every second.

For example:

  • 60Hz → 60 refreshes per second
  • 120Hz → 120 refreshes per second
  • 144Hz → 144 refreshes per second
  • 165Hz → 165 refreshes per second
  • 240Hz → 240 refreshes per second

Refresh rate is a specification of your monitor.

Unlike FPS, you don't increase your monitor's refresh rate simply by having a more powerful GPU.

If your monitor is rated for 144Hz, its maximum refresh rate is 144Hz unless you change to a monitor with a higher refresh rate.

FPS vs Refresh Rate

The easiest way to understand the difference is:

FPS = how many frames your PC produces.

Hz = how many times your monitor can refresh the image.

Your PC produces the frames.

Your monitor refreshes the screen.

For example:

144 FPS + 144Hz

Your PC is producing 144 frames per second, while your monitor can refresh 144 times per second.

Now compare that with:

240 FPS + 60Hz

Your PC is producing 240 frames per second, but your monitor can only refresh 60 times per second.

The two numbers are related, but they are not the same thing.

Does a 240Hz Monitor Give You 240 FPS?

No.

This is one of the most common misunderstandings when buying a gaming monitor.

A 240Hz monitor does not generate 240 FPS.

The monitor can refresh the screen up to 240 times per second, but your PC still has to produce the frames.

For example:

240Hz monitor + 60 FPS

Your monitor is capable of 240Hz, but your game is only producing 60 FPS.

You are still playing at approximately 60 FPS.

To take full advantage of a 240Hz monitor, your PC needs to be capable of producing much higher frame rates.

What Happens When FPS Is Lower Than Refresh Rate?

Let's say you have:

240Hz + 80 FPS

Your monitor can refresh 240 times per second, but your PC is only producing 80 frames per second.

The monitor cannot display 240 different frames if your PC is only producing 80.

The game will still be running at around 80 FPS.

The 240Hz monitor simply has additional capability that isn't being fully used.

This doesn't mean the monitor is useless.

If you upgrade your PC later and start getting higher FPS, the monitor can take advantage of those higher frame rates.

What Happens When FPS Is Higher Than Refresh Rate?

Now let's reverse the situation.

Imagine you have:

144Hz + 300 FPS

Your PC is producing 300 frames per second, but the monitor can only refresh 144 times per second.

The monitor cannot display all 300 frames as individual full refreshes every second.

However, high FPS can still be useful in some situations because new frames are being rendered more frequently.

This is particularly relevant for competitive gaming, where players may intentionally run very high FPS.

The important thing to remember is that the monitor is still physically limited by its 144Hz refresh rate.

What Happens When FPS and Refresh Rate Match?

When FPS and refresh rate are closely matched, your PC and monitor are operating at similar rates.

For example:

60 FPS + 60Hz

Your PC produces 60 frames per second.

Your monitor refreshes 60 times per second.

Or:

144 FPS + 144Hz

Your PC produces 144 frames per second.

Your monitor refreshes 144 times per second.

Or:

240 FPS + 240Hz

Your PC produces 240 frames per second.

Your monitor refreshes 240 times per second.

These combinations allow the monitor to make good use of the frame rate your PC is producing.

Why Does Higher FPS Feel Smoother?

Higher FPS means your PC is producing frames more frequently.

The time between each frame is approximately:

  • 60 FPS → 16.67ms
  • 120 FPS → 8.33ms
  • 144 FPS → 6.94ms
  • 165 FPS → 6.06ms
  • 240 FPS → 4.17ms

For example, at 60 FPS, a new frame is produced approximately every 16.67 milliseconds.

At 240 FPS, a new frame is produced approximately every 4.17 milliseconds.

This allows motion to be updated more frequently, which can make games feel smoother and more responsive.

Why Does Higher Refresh Rate Feel Smoother?

Refresh rate determines how frequently your monitor can update the displayed image.

For example:

60Hz

The monitor can refresh every 16.67ms.

144Hz

The monitor can refresh approximately every 6.94ms.

240Hz

The monitor can refresh approximately every 4.17ms.

This is why moving from a 60Hz monitor to a 144Hz or 240Hz monitor can make mouse movement, camera movement, and scrolling appear much smoother.

However, your PC still needs to produce enough FPS to take advantage of the higher refresh rate.

60Hz + 60 FPS

This is a basic but well-matched combination.

Your PC produces around 60 FPS and your monitor can refresh at 60Hz.

It's suitable for:

  • Basic gaming
  • Older games
  • Single-player games
  • General PC use

If you're happy with 60 FPS, a 60Hz monitor can display those frames.

144Hz + 144 FPS

This is a popular combination for PC gaming.

Your PC produces around 144 FPS and your monitor can refresh at 144Hz.

This allows you to take advantage of the higher frame rate and provides a significantly smoother experience compared with 60 FPS and 60Hz.

It's especially useful for fast-paced games.

240Hz + 240 FPS

This combination is designed for very high-FPS gaming.

Your PC produces around 240 FPS and your monitor can refresh at 240Hz.

This allows you to take advantage of the monitor's full refresh-rate capability.

It's particularly relevant for competitive games where players are targeting very high frame rates.

Do You Need Your FPS to Equal Your Refresh Rate?

No.

Your FPS and refresh rate don't have to be exactly the same.

For example:

100 FPS + 144Hz

Your PC is producing 100 FPS, while your monitor is capable of 144Hz.

That's perfectly fine.

Likewise:

180 FPS + 240Hz

Your PC is producing 180 FPS, while your monitor can refresh at 240Hz.

The monitor simply has additional refresh-rate capacity available.

You should think of refresh rate as the maximum refresh capability of your monitor, while FPS is the actual frame rate being produced by your PC.

How Much Difference Will You Notice?

The difference between lower and higher frame rates becomes easier to understand when looking at frame times.

For example:

  • 60 FPS → 16.67ms per frame
  • 120 FPS → 8.33ms per frame
  • 144 FPS → 6.94ms per frame
  • 240 FPS → 4.17ms per frame

Going from 60 FPS to 120 FPS cuts the time between frames roughly in half.

Going from 120 FPS to 240 FPS also cuts the frame time in half.

However, the visual difference between higher frame rates can become less obvious to some people as you move toward very high refresh rates.

Common FPS & Refresh Rate Mistakes

Thinking 240Hz Means 240 FPS

It doesn't.

Your monitor provides the 240Hz refresh rate.

Your PC has to produce the 240 FPS.

Buying a High-Refresh Monitor Without Enough FPS

If your PC normally produces only 60–80 FPS, you won't be fully using a 240Hz monitor.

Thinking More FPS Automatically Means More Refresh Rate

Your monitor has its own refresh-rate limit.

A 144Hz monitor doesn't become a 240Hz monitor just because your PC produces 240 FPS.

Thinking FPS and Hz Are the Same Thing

They aren't.

FPS comes from your PC.

Hz comes from your monitor.

Buying Based on Only One Number

When choosing a gaming monitor, consider how much FPS your PC can actually produce.

There's little point in buying an extremely high-refresh-rate monitor if your PC can't produce enough FPS to make use of it.

How to Match Your Monitor to Your PC

A simple way to think about it is:

60Hz Monitor

Good if your PC commonly produces around:

60 FPS

120Hz Monitor

Good if your PC commonly produces around:

80–120 FPS

144Hz–165Hz Monitor

Good if your PC commonly produces around:

120–165+ FPS

240Hz Monitor

Good if your PC commonly produces around:

180–240+ FPS

360Hz+ Monitor

Most useful when your PC can consistently produce extremely high FPS in the games you play.

Simple Rule for Understanding FPS vs Refresh Rate

If you don't want to overthink it:

FPS = frames produced by your PC

Hz = refreshes provided by your monitor

Higher FPS = more frames produced

Higher Hz = more refreshes available

For high-refresh gaming, you want your PC to produce enough FPS to take advantage of your monitor.

Your FPS doesn't have to exactly match your monitor's refresh rate.

What matters is understanding what each number represents and choosing hardware that makes sense for the performance your PC can actually deliver.

Final Thoughts

FPS and refresh rate are closely related, but they are not the same thing.

Your PC produces FPS, while your monitor provides the refresh rate.

A 240Hz monitor doesn't give you 240 FPS, and a powerful PC producing 240 FPS doesn't make a 60Hz monitor refresh at 240Hz.

For the best experience, you want your monitor's refresh rate to be high enough to take advantage of the FPS your PC can produce.

The simple way to remember it is:

FPS = what your PC produces.

Hz = what your monitor can display.

Match your monitor to the performance of your PC, and you'll get the most out of both.

What Are PCIe Add-in Card (AIC) SSDs? The High-Speed Storage You’ve Probably Overlooked

 When most people think about SSDs, they picture the slim 2.5-inch SATA drives or the tiny M.2 sticks. But there’s a third, less-talked-about option that offers serious performance— PCIe Add-in Card (AIC) SSDs . Whether you're building a workstation, running a server, or just want to go all out on speed, AIC SSDs might be your secret weapon. What Is a PCIe AIC SSD? A PCIe Add-in Card (AIC) SSD is an SSD that comes in the form of a PCIe expansion card —the same slot you'd normally use for a graphics card or sound card. Instead of plugging into a SATA port or M.2 slot, these SSDs go directly into a PCIe slot on your motherboard. How They Work AIC SSDs use the PCIe (Peripheral Component Interconnect Express) interface for ultra-fast data transfer They bypass the SATA bottleneck entirely Some AICs contain one large SSD , while others contain multiple M.2 NVMe drives in RAID configuration for extreme performance Form Factor & Installation F...
