What? well of course they are, what in the name of ????? would prompt you to say something like that?
#1 They didn't cut the price of 10 core CPU's in half out of the goodness of their hearts, Intel are not Santa Claus.
10 core CPU's at 3 time the cost of AMD's 16 core CPU's would have been the biggest joke on the Internet, they had no choice or lose massive market share to AMD, Intel are not so stupid as to carry on with the existing pricing structure as if AMD with 60% more cores at 35% the cost was just a bad dream, no, Intel can smell the coffee.
#2 The 14 core + CPU's are a last minute addition, added After Threadripper announcement, of course they are a reaction to Threadripper, even Motherboard Vendors said they had no idea those were coming.
