What are the differences among FreeSync, Adaptive-Sync, FreeSync Premium and G-Sync?
G-Sync is hardware optimization primarily for NVIDIA graphics cards (NVIDIA GPUs). FreeSync/Adaptive-Sync is primarily software optimization for AMD (Radeon GPUs). FreeSync technology dynamically updates refresh rates via software display ports and is compatible with HDMI and DisplayPort connections. Adaptive-Sync is an extension of FreeSync, requiring a DP1.2 cable and GTX10 series or higher graphics cards. Software requirements include Windows 10 and driver updates to version 417.71 or higher. NVIDIA's GeForce graphics cards are compatible with FreeSync/Adaptive-Sync, with restrictions similar to Adaptive-Sync.

At CES 2020, AMD redefined its FreeSync certification levels, discontinuing the older FreeSync and FreeSync 2 HDR categories, and introducing new tiers: FreeSync, FreeSync Premium, and FreeSync Premium Pro. FreeSync is the basic level, indicating that the monitor supports tear-free gaming when paired with AMD Radeon graphics cards and using a DisplayPort (DP) interface. FreeSync Premium certification requirements are stricter, requiring monitors to have at least 120Hz refresh rate, 1080P resolution, and support for Low Framerate Compensation (LFC).
The highest certification level is FreeSync Premium Pro, essentially replacing FreeSync 2 HDR, which mandates HDR support as a mandatory feature. For more details, you can refer to AMD's FreeSync (Gaming Smart Display) technology: https://www.amd.com/zh-hans/technologies/free-sync.
