You didn't read it till the end did you? nForce was an Nvidia chipset. This is the first time when it will be fully AMD.
Right because the chipset denotes the CPU brand. Like those ATI, ULI, or VIA boards that support both Intel and AMD. How do you differentiate? By stating which CPU goes in the board. Geeze man we had this figured out in 2003! If AMD CPU goes in, it's an AMD platform. If Intel CPU goes in, it's an Intel platform.
It says AMD Ryzen, not just AMD
The title was changed since yesterday, and rightfully so.
