It took a while to get here, but if the proof is in the eating of the pudding, FreeSync tastes just as good as G-SYNC when it comes to adaptive refresh rates. Perhaps more importantly, while youre not getting a free monitor upgrade, the current prices of the FreeSync displays are very close to what youd pay for an equivalent display that doesnt have adaptive sync. Thats great news, and with the major scaler manufacturers on board with adaptive sync the price disparity should only shrink over time.
The short summary is that FreeSync works just as youd expect, and at least in our limited testing so far there have been no problems. Which isnt to say that FreeSync will work with every possible AMD setup right now. As noted last month, the initial FreeSync driver that AMD provided (Catalyst 15.3 Beta 1) only allows FreeSync to work with single GPU configurations. Another driver should be coming next month that will support FreeSync with CrossFire setups.

http://hothardware.com/reviews/amd-freesync-and-lg-34um67-widescreen-monitor-reviewThe two graphs above show how frame rates are affected when enabling / disabling V-Sync. With V-Sync enabled (red line) on a display that has a refresh rate of 60Hz, and the games configured for high image quality settings to target the 40-60 FPS range, it is not uncommon to see frame rates bounce between 60 and 30 FPS for a time (half the monitor's refresh rate), which means many frames are duplicated, which introduces lag. We should mention that this is another area where FreeSync has an advantage over G-SYNC. With FreeSync, if V-Sync is disabled, frame rates are not limited by the max refresh rate of the connected display.
http://www.tomshardware.com/news/amd-project-freesync-launch,28759.htmlAlong with this information, AMD also gave some performance data. It has long been a question of whether FreeSync will have any performance impact, and to answer this AMD has done some tests of its own. On identical platforms using a Z87 motherboard and an i7-4770K processor, AMD said that enabling FreeSync actually improved performance by about 0.2 percent when using an R9 290X. When using a GTX 780, AMD actually observed that its competitor's technology, G-Sync, reduced performance by about 1.5 percent.

If there's one thing tech market doesn't need, it's another standards cat fight. But you survived Firewire vs. USB, HD-DVD vs. Blu-ray, and RDRAM vs. DDR so get ready for the battle between Nvidia's G-Sync and AMD's FreeSync to kick into high gear.

But back to the consumer who will be forced to choose between the two when buying a monitor. If the 11 monitors that support FreeSync actually all appear, it would mean AMD has an advantage in support. Even almost a year and a half after announcing G-Sync, the number of current G-Sync panels is six according to Nvidia's own page. If AMD is right, and we see 20 FreeSync panels by the end of this year, that's a strength in numbers G-Sync has never enjoyed.
Nvidia's strength, on the other hand, is the popularity of its GPUs. Most hardware surveys give Nvidia roughly a 2:1 advantage in discrete graphics market share, which means there's a higher chance of a gamer buying a G-Sync monitor to match his or her Nvidia GPU.
To balance that out, monitor's using FreeSync appear to have a price advantage:

http://hexus.net/tech/reviews/monitors/81694-lg-34um67-amd-freesync-monitor/The LG 34UM67 has an MSRP of $649 while its little brother, the 29UM67, can be purchased for $449. Compared to other ultrawide monitors the new LG FreeSync display holds no additional price premium. In fact, the monitor is cheaper than the equivalently spec'd LG 34UM65 which lacks FreeSync support. Such aggressive pricing bodes well for the competitiveness of FreeSync displays in the marketplace.
