What is AMD FreeSync?

AMD FreeSync is an adaptive synchronization technology developed by AMD for LCD and OLED displays that support a variable refresh rate. It is designed to prevent screen tearing and reduce stuttering caused by misalignment between the screens refresh rate and the contents frame rate. FreeSync is an open standard, royalty-free technology that is aimed at providing a smooth, tearing-free, and low-latency gaming experience. It was first announced in 2014 as a competitor to Nvidias proprietary G-Sync and is based on VESAs Adaptive-Sync protocol, working over DisplayPort and HDMI ports. FreeSync technology requires both a monitor and an AMD Radeon graphics card with FreeSync support to function effectively.

There are different tiers of FreeSync technology, including FreeSync, FreeSync Premium, and FreeSync Premium Pro, each with specific requirements and features. FreeSync Premium Pro, for example, adds requirements for the display to meet AMD FreeSync Premium Pro compliance tests and is particularly focused on delivering an exceptional user experience when playing HDR games.

In summary, AMD FreeSync is a technology that leverages industry standards to deliver dynamic refresh rates, aiming to provide a smoother and more immersive gaming experience by synchronizing the displays refresh rate with the contents frame rate, thereby reducing tearing and stuttering.
