"..with the sole objective of competing with first generation Ryzen processors"
Wonder who decided it'd be best to (attempt) put that little semi-spin on it, especially in light of the fact that Kaby Lake CPUs were reviewed, shipping, and delivered months before the first Ryzen was benchmarked in any games.
Why is it important who did it?
It's obvious that Kaby Lake was released well ahead of the regular schedule. Should normally have been released around the same time as the first Ryzen.
Intel probably had a pretty good hunch that Ryzen would be good, and therefore decided to grab some extra market share of the 4Q16 and 1H17 sales by this earlier release. Otherwise more consumers would wait and compare Ryzen to Kaby Lake before buying, and end up going with Ryzen.
