Nvidia calls its proprietary implementation G-Sync, and has been shipping G-Sync displays with partner manufacturers for over a year, while AMD worked with VESA (Video Electronics Standard Association) to build support for Adaptive Sync (aka FreeSync) into the DisplayPort 1.2a standard. Now, with FreeSync displays finally shipping as of today, it’ll soon be possible to do a head-to-head comparison between them.
AMD first demonstrated what it calls FreeSync back in 2013. Modern Graphics Core Next (GCN) graphics cards from AMD already had the ability to control display refresh rates — that technology is baked into the embedded Display Port standard (eDP).
Bringing it over to the desktop, however, was a trickier proposition. It’s taken a long time for monitors that support DisplayPort 1.2a to come to market, which gave Nvidia a significant time-to-market advantage. Now that FreeSync displays are finally shipping, let’s review how the RS Gold
