The Tech Report learned yesterday of a feature that AMD has been offering over the past three generations of GPU called dynamic refresh rate, which they billed as a power saving feature. Skipping an unnecessary vertical screen refresh would certainly save you a bit of power but really isn't that attractive a feature. NVIDIA looked at this feature in the opposite way, not to save power but to refresh your screen as quickly as it is capable of to provide much smoother graphics and that marketing has had G-SYNC on everyone's lips. Assuming AMD can get the word out, their variable refresh rate technology should be compatible with most new mobile/laptop products based on the EDP specification, no additional costs or equipment required.
"During an impromptu meeting in a hotel ballroom this morning, we got an eye-opening demo of a dynamic refresh rate capability that's been a part of Radeon GPUs for several generations. AMD thinks this feature can be combined with triple buffering to deliver G-Sync-like animation smoothness without the cost associated with specialized display hardware."
