G-Sync vs FreeSync

Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware.

Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM.

These new MediaTek scalers will support all the same features that current dedicated G-Sync modules do. Nvidia says that three G-Sync monitors with MediaTek scaler chips inside will launch "later this year": the Asus ROG Swift PG27AQNR, the Acer Predator XB273U F5, and the AOC AGON PRO AG276QSG2. These are all 27-inch 1440p displays with maximum refresh rates of 360 Hz.

G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens.
