Doesn't Radeon VII include Navi? Or is that the new Vega II Architecture?
Either way this is awesome. If that's just Vega the RX series will go down in price and that makes the RX series basically low end and mid range GPU's when the Vega series is the super high end. This means they cover all ends of the market. Once Navi comes out it'll be even better because the low and mid range GPU's will be smaller, faster, quieter, and more efficient.
NAVI is going to be new architecture. I believe the new Vega will compete against the RTX 2080. If performance goes well it will bring down the cost for sure until something can dethrone the 2080ti
