AMD could counter Nvidia’s G-Sync with simpler, free sync tech

CES — During an impromptu meeting in a hotel ballroom this morning, I got an eye-opening demo orchestrated by AMD Graphics CTO Raja Koduri. He had a pair of relatively inexpensive laptops sitting side by side running a simple graphics demo showing a windmill with the blades in motion. One of the laptops was using traditional vsync, only refreshing the display at a fixed rate, and the quantization effect of the fixed refresh cycle introduced obvious roughness into the animation. On the other laptop, however, the motion was much smoother, with no apparent tearing or slowdowns—much like you’d see from Nvidia’s G-Sync technology.
