AMD and Nvidia both support adaptive sync technologies—FreeSync and G-Sync, respectively—that, at their core, match a display's refresh rate to the GPU's render rate. This eliminates screen tearing and results in smoother gameplay. As it turns out, Intel is also planning to support adaptive sync, as it's said in the past, and we've recently learned those plans include the company's upcoming discrete GPUs.

Let's back up a moment. Several years ago, it was reported that Intel was working on supporting VESA's adaptive sync technology in its discrete GPUs. Adaptive sync forms the basis of AMD's Freesync technology, and is an open standard that companies are free to use without paying royalties. In effect, adaptive sync support is synonymous with FreeSync support (but not FreeSync 2, which has additional feature requirements).
