why will AMD have to cut prices?
Skylake-X i predict will be so overpriced that AMD will still have the win in the performance / dollar aspect.
Obviously it depends on what they price the cheaper 6 core. I'm assuming the price will be low enough to force AMD to cut prices when you factor in that Skylake-X will widen the IPC and clock speed gap. It could be just something as simple as removing the 1700 and putting the 1700X in the 1700 price bracket.
