AMD’s FreeSync technology is their answer from NVIDIA’s proprietary G-Sync technology. It appears that not all AMD GPU’s will be supported by the technology. Only GPU’s based on “Hawaii” and “Tonga” silicon will be supported. So this includes the R9 285, R9 290, R9 290X and R9 295X2.
It was originally thought that FreeSync would be supported on any graphics card where the DisplayPort was standardized, but this turns out not to be true. According to a report by TheTechReport only the latest silicon from AMD is supports. From their article, “That means brand-new cards like the Radeon R9 280, 280X, 270, and 270X won’t be FreeSync-capable. Nor will any older Radeons in the HD 7000 and 8000 series. AMD tells us these prior-gen GPUs don’t have the necessary support for the latest DisplayPort standard.”
So if you are looking into FreeSync make sure you have a graphics card that supports it.
