At this point, only AMD is using this standard, so the support is about equivalent between the two, but AMD does have the advantage of also supporting it on their Radeon graphics equipped series of APUs. "FreeSync" is mostly used for marketing and requires certification and licensing from AMD for use. It's a pretty mature technology, so it's quite likely that if you bought an NVIDIA-equipped computer in recent years, it supports G-SYNC.ĪMD released the FreeSync protocol for open use through the VESA consortium as an official part of the DisplayPort interface, so anybody, including competitors NVIDIA and Intel, can use the open Adaptive Sync standard for their devices (due to inherent limitations, NVIDIA actually uses the open standard for G-SYNC equipped laptops). Learn more about input lag Supported Graphics Cardsĭue to its proprietary nature, G-SYNC can only be used with NVIDIA graphics cards. Winner: FreeSync. While G-SYNC offers the certainty of low input lag, FreeSync offers more versatility which is useful if you plan to use your monitor with multiple devices. Unlike G-SYNC, FreeSync is supported over HDMI, but FreeSync over HDMI is not yet an Open Standard as it is with DisplayPort, so it only officially works on AMD graphics cards, including with the Xbox One. FreeSync monitors can have as many inputs as the manufacturer desires, including legacy ports like VGA or DVI (FreeSync, however, only works on HDMI or DP). Newer ones that do feature an HDMI port in addition to DisplayPort 1.2 are usually limited to HDMI 1.4, which can be bandwidth constrained at higher refresh rates or resolutions, and it doesn't have G-SYNC functionality. G-SYNC modules only support 1 to 2 inputs, depending on the generation. The use of generic hardware has an advantage though. It doesn't mean that FreeSync screens have inherently higher input lag, but you'll have to look at reviews for an input lag measurement before making your purchase. FreeSync monitors, on the other hand, are in the same position as standard non-adaptive monitors. Since all G-SYNC monitors use the same NVIDIA-made hardware which was designed from the ground up to be focused on gaming, they tend to have a low input lag. Variable refresh rate eliminates stutters.Low input lag thanks to the gaming-focused G-SYNC module.Most of the monitors only have a single input.While it's more expensive, it offers a standardized experience across devices. It is often the case that certain monitors only support the feature within a limited frequency range, reducing the usefulness of it. This sounds great in theory, but in practice, it means that the FreeSync implementation is entirely up to the manufacturer. This gives the advantage of not increasing the costs of the hardware but also allows manufacturers to easily adapt existing designs (hence "Free"). ![]() All G-SYNC features only work with NVIDIA graphics, and are disabled when used with other sources.ĪMD's FreeSync is essentially the same concept, but instead of requiring expensive proprietary hardware, it works on traditional off-the-shelf components. This was implemented as an NVIDIA G-SYNC module that replaces standard display scalers. NVIDIA was the first to propose a hardware solution that would solve tearing while retaining the responsiveness and simplicity of unsynchronized displays. Unfortunately, this isn't the best solution, since it tends to raise input lag dramatically and often doesn't provide a consistent experience with highly fluctuating framerates. VSync works by limiting the application's frame rate to the vertical refresh rate of the monitor and only sending out a new frame when the screen is ready to receive one. G-SYNC covers the entire refresh rate down to 30Hz (even lower with Low Framerate Compensation)īoth technologies refer to the software solution named Vertical Synchronization (or VSync for short) which has been used with display adapters for decades now.Requires expensive NVIDIA-made display interface.
