One other thing to keep in mind when examining potential Zen memory bandwidth requirements: AMD has been losing memory bandwidth for years due to poor IMC performance. The last best-in-class IMC they had was from K8 (it had no competition in the x86 world). Intel has been consistently outperforming AMD in the IMC department since Nehalem. They got more out of DDR3-1600 than AMD. Zen needs to turn around that situation. If it does, then that's just another factor that could contribute to 8c/16t Summit Ridge existing quite happily with only two DDR4 channels. Even something as pedestrian as DDR4-2666 should work if they can produce better results from the Zen IMC.
