That isn't my logic at all, for one thing, BD wasn't actually competitive in any shape or form.
Code:
bloomfield 4 core 45nm 263mm 4/4/4 284/562/999
gulftown 6 core 32nm 248mm 6 999
sandy-E 6 core 32nm 435mm 4/6/6 285/555/990
haswell-E 8 core 22nm 358mm 6/6/8 389/583/999
broadwell-E 10 core 14nm 246mm 6/6/8/10 434/617/1089/1723
skylake-X 12 core 14nm ??? 6/8/10/12 389/599/999/1199
making this stuff line up is a nightmare......
Now you can argue this many ways, but one thing its worth point out is that the two lowest models generally had the same core count. which now shifts the 8 to the second lowest instead of the 3rd lowest. So the pricing brackets have stayed the same ( except that insane 1700) but the SKU design has changed.
If Zen didn't exist would the 8 core be the second lowest SKU? would it be 6/6/8/10/12 at something like 389/580/900/1200/1700. Given the lowest 6 core has stayed the same price for 3 generations what does that tell you?
It tells me that are really working too hard around the fact this is a natural move, the only price backets that we can compare to the past are the 400, 600 and 1000 ones, this was the time that a 10C whould overtake 8C in the $1000 price tier forcing it down to $600, the HEDT history backs that one up. Thats hard evidence right there, and you are making that one up based on what "might have happen".
C2E 2006-2007 4C.
Gulftown increased $1000 tier cores to 6C (2010), dropping 4C to $600 tier,
SB-E (2011-12) and Ivy-E (2013) maintained it.
HSW-E (2014) did Increase it to 8C, dropping 6C to $600 price tier
Broadwell-E (2016) maintained it,
Based on that there is no reason to belive that SKL-X whould not bring 10C to $1000 tier and dropping 8C down to $600. This is something that had happen before at the 3+ year mark, not once, but twice now.
Not sure why this need to belive everything in the world is thanks to AMD. /period.
You know what could have been Ryzen influence? if Intel dropped 8C all the way down to $400, that is a good example of something that never happened before.
