FreeSync vs G-Sync : What you need to know – Reviewires

It’s critical to evaluate FreeSync vs G-Sync when purchasing a gaming monitor. Both approaches increase monitor performance by synchronizing the screen’s performance with the graphics card’s performance.

However, each has its own benefits and drawbacks: FreeSync is prone to screen abnormalities such as ghosting, but G-Sync provides superior performance at a higher cost.

Furthermore, the greatest gaming monitors have had something of a revival in recent years. Before introducing Adaptive-Sync technology in the form of Nvidia G-Sync and AMD FreeSync, performance-oriented gamers could only aspire for greater resolutions or a refresh rate exceeding 60 Hz. 

However, we now have monitors that run at 144 Hz or higher regularly, but Nvidia and AMD have also updated their respective technology. In the duel of FreeSync vs. G-Sync in the age of gaming displays, which Adaptive-Sync technology reigns supreme?


FreeSync, developed by AMD, and G-SYNC, developed by NVIDIA. They perform very similarly, but a few distinctions between the two are worth noting.

So, first, let us define FreeSync and G-Sync, as well as their benefits.

What is Freesync?

FreeSync is AMD’s alternative to G-Sync and is only compatible with AMD graphics cards. Though it employs the same basic adaptive refresh technology as its competitor, AMD has confined the technology to the graphics card by utilizing the existing VESA Adaptive-Sync standard. 

However, this means that, unlike G-Sync, it does not require a chip or even special licensing on the display side. As a result, FreeSync is essentially open-source, which means compatible displays are usually more widely available and less expensive to consumers.

Advantages of FreeSync

  1. The main advantage of FreeSync is the increased availability of compatible displays due to the openness of AMD’s model. FreeSync monitors are also available in mid-and entry-level configurations.
  2. It operates with HDMI.
  3. There are no input restrictions.
  4. Stuttering is eliminated by using a variable refresh rate.
  5. Input lag is determined by the manufacturer’s design.
  6. HDR API hardware support.
  7. Compensation for low frame rate.
  8. Support for windowed mode.

What is G-Sync?

G-Sync is NVIDIA’s proprietary solution to screen tearing that uses adaptive refresh technology and is only compatible with NVIDIA graphics cards. Essentially, this means that your frame rate and refresh rate are synced up to the monitor’s maximum refresh rate. So, if your GPU delivers 98 frames per second on a 120 Hz display, the two will sync at 98Hz.

Adding further, G-Sync works by embedding an NVIDIA-supplied hardware module in the supported monitor, giving NVIDIA control over which display partners they certify through a stringent licensing process. Moreover, this gives NVIDIA tight control over quality assurance, which means that G-Sync displays are generally more expensive.

Advantages of G-Sync

  1. Stuttering is eliminated by using a variable refresh rate.
  2. Gaming-focused G-SYNC module provides low input lag.
  3. The majority of monitors only have one input.
  4. Though both technologies perform similarly at higher frame rates, G-Sync appears to have an advantage at rates lower than the display’s stated minimum refresh rate.
  5. Because G-Sync is only compatible with NVIDIA cards, and NVIDIA currently has a large market share advantage over the competition, a G-Sync monitor is more likely to apply to you and your current gaming PC.
  6. Support for windowed mode
  7. ULMB (Backlight Flicker)
  8. Overdrive (variable)
  9. Compensation for low frame rate

Difference between FreeSync and G-Sync.

Before starting the difference, we know that we should use G-Sync if we have an Nvidia GPU, whereas FreeSync if we have an AMD GPU. However, if you have a choice between monitors or graphics cards, you might wonder what the differences are and which syncing technology is best for your setup. Let’s break it down to see which one is a better fit for you.


While G-Sync is a proprietary Nvidia technology that requires permission and cooperation from the company, FreeSync is available to any developer or manufacturer for free. As a result, there are more monitors available that support FreeSync. However, G-Sync and Freesync don’t just feature; they’re also certifications that monitor manufacturers must meet. While basic specifications allow for frame syncing, more stringent premium versions of G-Sync and Freesync are also available. Further, if monitor manufacturers meet these higher standards, users can be confident that the monitors are also of higher quality.


G-Sync is enabled by a built-in chip in the monitor’s design. FreeSync uses the video card’s functionality to manage the monitor’s refresh rate using the Adaptive-Sync standard built into the DisplayPort standard, resulting in a performance difference.

Moreover, when the frame rate isn’t consistently syncing within the refresh range of the monitor, both FreeSync and G-Sync suffer. Additionally, G-Sync can exhibit flickering issues at very low frame rates, and while the technology usually compensates to correct it, there are exceptions.

Meanwhile, FreeSync suffers from stuttering when the frame rate falls below a monitor’s minimum refresh rate. Adding further, some FreeSync monitors have a very narrow adaptive refresh range, and if your video card cannot deliver frames within that range, issues arise.

Premium version of free sync and G-Sync.

FreeSync premium version

Premium monitors must support a native 120Hz refresh rate to provide a flawless 1080p resolution experience. Further, it includes low frame rate compensation (LFC), which copies and extends frames if the frame rate drops to smooth out more jarring experiences.

G-Sync premium version

Ultimate is similar to FreeSync Premium Pro in that it is a more advanced option available on more powerful GPUs and monitors designed for HDR support and low latency. Moreover, it used to be that a minimum brightness of 1,000 nits was required, but that has recently been reduced to VESA HDR400 compatibility or around 400 nits.

Frequently Asked Questions

Are G-Sync and FreeSync worth it?

Yes, just as G-Sync is worthwhile in the right circumstances and for the right user, so is FreeSync in certain scenarios and for certain users.

Is free sync good?

As long as you have a compatible GPU, AMD FreeSync is worth it because it eliminates screen tearing and stuttering at no extra cost to the monitor.

Why is G-Sync expensive?

For a time, one could argue that the G-Sync chips drove up the price of monitors because they added value to the display in terms of image quality and performance.

Does G-Sync make a difference?

Gsync makes a world of difference. It’s the biggest difference in how our games are displayed that has come along in a very long time.

Is FreeSync or G-sync necessary?

A high refresh rate g-sync or freesync monitor allows you to enjoy both a screen-tearing-free experience and the maximum frames possible for your computer, reducing input lag.


We came to an end to knowing the difference between freesync and G-sync and learned that there is no clear winner between the two technologies, depending on your needs and preferences. In most cases, choosing the technology that works with your computer is the best option: G-SYNC if you have an NVIDIA graphics card, and FreeSync if you have an AMD graphics card. 

However, When comparing them directly, the most important feature works the same on both, but G-SYNC tends to offer a more polished and consistent platform for a premium (which means that the best monitors around are mostly G-SYNC), Whereas, capabilities can vary wildly between the wide range of FreeSync models found in every price range.
