Excellent news on CPUs and I wouldn't worry about Polaris, we already knew Vega was going to be the high-end GPU, while in the mid-range a die-shrink and so a significant reduction of production costs and power consumption was probably more important, not to mention that there is a not stellar, but still very nice performance boost too compared to current Radeons, with only the NVidia GTX 1080 beating Polaris, but at cost of a much higher power consumption, and most probably higher retail price and production costs too, making NVidia less attractive for the average user, and when Vega will be launched, for the power users too.
All these news, and Polaris 10 and 11 segments bode very well for the next gens of APUs too, most probably Zen-Polaris APUs will be more than enough for basic gaming PCs, and adding a discrete GPU with crossfire, on well designed mobos, obviously, they could become very fine high-end ones too.
