Anandtech also did a piece on this and there was one thing that really stood out:
Meanwhile we do have limited information on the interface itself; G-Sync is designed to work over DisplayPort (since it’s packet based), with NVIDIA manipulating the timing of the v-blank signal to indicate a refresh. Importantly, this indicates that NVIDIA may not be significantly modifying the DisplayPort protocol, which at least cracks open the door to other implementations on the source/video card side.
So it might indicate that they aren't using specific hardware on the GPU-side, just software. On the screen though, you need a new controller because it must accept the variable v-blank signal.
Also this:
I can't stress enough just how smooth the G-Sync experience was, it's a game changer.
Too bad it requires a specific set of monitors.
