Intel is trying desperately to maintain the image of "premium brand" and "premium brands" don't discount and don't lower prices based on what their competition is doing.Can't wait to see how Intel defines "Relative price-performance per core".... I think it's significant there are no actual performance benchmarks--probably, the bar chart is formulated on the 50% price cut, rather than performance, thus the higher "relative price performance" per core since Intel will be giving these things away, apparently. Highly amusing... In the old days, Intel didn't even like to acknowledge the existence of AMD--now, Intel's ads seem rather bizarre, and rather desperate.
Got to get rid of excess inventory sooner or later and now that there is some significant pricing pressure at the high-end, Intel won't get to just hold launch prices until it discontinues parts if it wants to keep inventory moving. Something it mostly hasn't had to do in nearly twelve years.This is why they either have to cut Skylake X pricing or accept that they will never sell a single one after Cascade Lake X starts shipping.
Also considering that it can be said (although more a "technicality" than a reality for 99% of users) that 9700k and 9900k are still the best for gaming - Intel can use that to justify the higher prices on those parts - and will continue as long as this perception is maintained for the most part - especially in the wake of whatever is causing their supply issues....
I wish the downward pricing pressure got more intense in the mainstream, though there is effectively no chance of that happening while Intel is still struggling to meet demand, leaving AMD free to inflate its own profit margins.
