Im also in the we need to wait and see actual real benchmarks bandwagon before getting to carried away. BUT even if only 1/10th of the leaks are accurate then its safe to say that Ryzen does require a reaction, and intel should be planning that reaction already.
Well, if they didn't have something much better than KL in the pipeline already, they can't really react any time soon, except with prices.
Unless Intel has that 10nm chip up it's sleeve and ready...
I haven't seen any leaks except prices that would indicate that Intel needs to do anything. Intel can lower chip prices any time they want.
At best, AMD seems to be releasing a chip that has caught up with Intel's 2-3 year old DT designs. If I were Intel I'd worry strictly about the pricing until AMD shows something better than what has been leaked.
For me, it is the RyZen based APUs that are a real threat to Intel's IGP monopoly.
Maybe we will finally find out what a full power 72EU Intel IGP can do in a desktop.
I think the 7740K and 7640K are an indication that Intel has not reacted and doesn't have anything to react with. Those chips were just what Intel was doing anyway.
