AMD has demonstrated its variable refresh rate technology at CES 2014 and the folks at Anandtech got a hands on demonstration of the tech in action. AMD demonstrated variable refresh rate technology. There’s apparently already a VESA standard for controlling VBLANK intervals. The GPU’s display engine needs to support it, as do the panel and display hardware itself. If all of the components support this spec however, then you can get what appears to be the equivalent of G-Sync without any extra hardware.
