Sync or Swim: GPU Sync Technologies

Over the past few years, we have seen significant advancements in the tech industry at a pace that has been faster than ever before. However, with better technology comes more critical challenges that need to be resolved at a time. In terms of display technology, when frame rates and refresh rates increased, screen tearing became an issue that must be addressed. Here comes the magic of GPU Sync technologies.

GPU sync technologies are essential for a smooth and tear-free gaming experience. They synchronise the refresh rate of your monitor with the frame rate of your graphics card to eliminate tearing. There are two leading names in the world of GPU sync technologies: Nvidia G-Sync and AMD FreeSync. Both technologies work similarly, but they differ in a few aspects.

Nvidia introduced the patented technology known as G-Sync. Your monitor must have an integrated G-Sync module to make the most out of this technology. Although G-Sync monitors cost more than FreeSync monitors, they work better and have a more extensive refresh rate range. On the other hand, FreeSync is an open-source invention of AMD. FreeSync displays typically don’t need a proprietary module to function and

Nonetheless, to thoroughly squeeze the benefits of each GPU Sync technology, your monitor must be connected to a compatible graphics card. Let’s look deeper at how G-Sync and FreeSync work, compare the two technologies in more detail and discover which is right for you.

1.   What is GPU Sync Technology and How Does it Work?

GPU sync technology solves several problems that can severely interrupt your visual experience. Screen tearing is the core challenge in a fast-paced activity. Without the adaptive Sync feature, your monitor will always display content at its specified refresh rate, typically 60 Hz or 60 refreshes per second. An unwanted artefact arises when the refresh cycle occurs in between the display of two frames, showing a portion of both frames at the same time. This is something we call “screen tearing”.

Screen tearing is a trouble, and you can quickly notice it in your games or content creation. To fix it, new monitors are designed with a technique called GPU Sync, V-Sync, or Adaptive-Sync that synchronises the frame rate of your GPU with the refresh rate of your screen, resulting in minimal ghosting and motion blur.

This sync feature is a better solution for your monitor that ends a variable refresh rate (VRR) signal to the monitor. After that, the monitor adjusts its refresh rate following the graphics card’s frame rate.

By doing this, it is ensured that every frame is displayed accurately before the next is rendered. GPU synchronisation is beneficial for gaming; it may also be helpful in tasks where high colour image accuracy and smoothness matter a lot, like motion graphics and video editing.

2.   What is Nvidia G-Sync?

NVIDIA is the biggest name in the computer graphics industry. Over the years, it has introduced and implemented an incredible solution to reduce screen tearing and other challenges. This excellent technology was introduced in 2013 by Nvidia and gained significant popularity quickly because monitor refresh rates are always better than the GPU’s capability to render the data. This is called “G-Sync”.

In essence, Nvidia G Sync technology is a hardware-based adaptive refresh feature incorporated into the latest monitors to prevent screen stuttering and juddering. Not only is it a VRR technology, but it has also become a gold standard for providing seamless and smoother performance in content creation and gaming.

If your monitor supports G-Sync, you have the added peace of mind that the display and graphics will actively communicate to refresh the screen on every new frame. The standout benefit of G-Sync is that it prevents screen tearing, motion blur, and other common jargon of V-Sync. However, apart from the cutting-edge Nvidia graphics card, you must have a high-performance monitor with a pre-built G-Sync feature.

3.   What is AMD FreeSync?

AMD FreeSync was introduced by Advanced Micro Devices (AMD) in 2015. Just like Nvidia G Sync, this technology works to align the refresh rate of your display with the frame rate of the graphics card of your desktop PC.

This feature also provides smoother and more fluid gameplay and lag-free visual experiences. There are three versions of AMD FreeSync available in the market, including FreeSync, FreeSync Premium, and FreeSync Premium Pro.

FreeSync Premium and FreeSync Premium Pro provide a refresh rate of at least 120Hz and low frame rate compensation. At the same time, the FreeSync Premium Pro goes on higher than 144Hz and supports HDR functionality.

FreeSync also has made significant progress beyond the traditional V-Sync standard, although it could be better. One of its most notable disadvantages is the prevalence of ghosting. Ghosting is where a visual appears on screen as a shadow because it leaves a slight trace of its previous image position.

4.   G-Sync vs. FreeSync: What’s the Difference?

AMD FreeSync and Nvidia G-Sync are designed to serve a similar purpose, which leads to an obvious question: if that’s right, what is the notable distinction?

The significant difference between FreeSync and G-sync is the connectivity requirements. While G-Sync only works with DisplayPort unless the user has a G-Sync-compatible monitor, FreeSync needs an HDMI or DisplayPort connection to turn on.

Nvidia G-Sync Compatible is the most common type of G-Sync that follows the VESA Adaptive Sync standard. In comparison, Nvidia G-Sync and G-Sync Ultimate are more premium versions of G-Sync that are based on the proprietary hardware in the display.

G-Sync is unique and only supports adaptive Sync with Nvidia graphics hardware. On the contrary, FreeSync also supports NVIDIA video cards and AMD graphics. G-Sync supports a range of high-speed panels from 75 Hz to 360 Hz. While FeeSync has at least 120 Hz refresh rates at minimum FHD resolution.

Another difference boils down to the certification and testing of both technologies. Monitors must pass the certification programmes that AMD and Nvidia have set up to claim formal compatibility with their respective technologies.

The reason that not all VESA Adaptive Sync displays can immediately be claimed to be AMD FreeSync or Nvidia G-Sync Compatible is because of this rigorous certification process. The certification guarantees that consumers get the benefits of both technologies as promised without sacrificing compatibility or performance.

5.   Sync or Swim: Which GPU Sync Technology is Right for You?

Nvidia G Sync and AMD FreeSync are the two standard GPU Sync technologies that work on adaptive Sync. G-Sync and FreeSync equipment provide various offerings to fit virtually any need and budget.

If you have an NVIDIA graphics card and want smooth motions without tearing and are willing to pay a premium for a monitor, then a G-Sync is the best bet. On the other hand, FreeSync is the right option if you are looking for low input lag and are okay with minimal tearing on a budget.

Your best course of action is to your specific hardware, budget, and digital preferences when choosing between the two.

So, whether you choose to sync or swim, the goal remains: to immerse yourself in a visually flawless, smooth, lag or tear-free digital realm!
