Last week, Tom's Hardware teamed up with Newegg, NVIDIA, AMD, Digital Storm and a few other companies for a massive side-by-side blind test of NVIDIA's G-Sync technology versus AMD's FreeSync technology.
The setup involved using both IPS- and TN-based panels in the form of the Acer XB270HU (G-Sync) vs. the ASUS MG279Q (FreeSync) which are both based on IPS panels with a native resolution of 2560x1440. The other two displays are the ASUS PG278Q (S-Sync) vs. the BenQ XL2730Z (FreeSync) which are TN-based panels. Hardware wise, an NVIDIA GeForce GTX 970 and AMD Radeon R9 390X were used inside of some well-specced Digital Storm gaming PCs.
The overall test had NVIDIA winning by a huge margin, with 60% of the participants choosing G-Sync based on this experiment. The remaining 40% was split into 21% choosing FreeSync, while 19% thought both were of equal quality. When it came to one of my favorite games to play to show people G-Sync's benefits, Battlefield 4, G-Sync scooped it up with 8 out the 12 users saying that G-Sync was best on Battlefield 4. FreeSync had just three people choosing FreeSync over G-Sync, while one thought it was of equal quality.
Interestingly, 34 of the 48 participants in this elaborate test said that they would pay a premium to play games using a 27-inch 2560x1440 IPS-based 144Hz monitor using G-Sync or FreeSync, with 16 out of 28 people saying they'd pay up to $100 more. Nine of the participants said that they'd pay between $100-$200 more, while three of them said they'd shell out $200 or more.
