Intel directed too much money in diversifying dies rather than competing on pure architecturañ changes. Intel has high revenues because they wont even do die harvesting for the 90% of the skus they launch. AMD has to face intel with 3 dies, whereas intel makes at least 3 for mobile only.
These thing make Intel also a slower moving target. For Intel to nullify AMD they have to invest more money than nornally, which is the first sight of a decaying revenue.
For the enthusiast market, Summit Ridge is sure a punch in the gut, because they made what everyone was asking in that purchasers group: get rid of the igp for more cpu performance.
In the prebuilt area intel still has an advantage with its igpu, also because amd is still building stock of harvested dies and RR isnt yet ready. But RR will be a massive blow to Intel 's revenue in consumer space because they lost the only thing they had in their favour, and their iGPUs are totally inneficient from an mm2 to performance ratio. Their salving grace is having 4 dies to fight just 1 (for now, i bet if AMD does well we will see more dies rolling in to avoid 50% harvested skus).
In the server market Intel has totally secured the hpc space. Everything that doesnt relly on avx2 and 256b wide fpus is up for grabs. And if you tought ryzen 7 murdered bwe value proposition, check the e5 v4 prices to see that AMD has a lot of leeway to get marketshare, because perf/w is good and so is TCO.
