The current top bin i3 is 147$. Meaning it cant be below that. And the unlocked i5 carries a 24$ premium.
So you say it would take sales away. Shouldnt the poll reflect this then? Unlocked i3, but 20$ more for an i5 K model?
Z77 48$
H77 43$
Z75 40$
B75 37$.
Everyone still buys Z77 instead of Z75. And for the same reason there wont be a Z85. The market yet again decided it didnt want it. When the time to vote with the wallet arrived.
the trouble with the z75 is lack of availability (from the motherboards manufacturer side I think), if the MB was $10 cheaper with the rest unchanged (apart from the chipset related changes), why not? but in reality some z77 boards are cheaper, there is just a higher volume, looking on newegg the cheapest z77 cost the same as the cheapest z75, in that case... why bother... with a $8 cheaper chipset and the same price... oh well, no wonder no one is buying z75...
as for the i3, it's true that the most expensive i3 is badly priced, but that's why I used "average", the average i3 uses the most basic IGP, the K i3 could be something different, to hold some appeal it would have to cost less than $175, so they should give you no HD4000 (maybe no IGP at all, like the 2550K) and a lower default clock (I still find it interesting that the K, the overclock friendly CPUs come with the best IGP, when most IGP users go with cheaper CPUs...), and a $150 or lower price.... if the cost was to high, than it would fail of course, but I don't see why Intel couldn't sell it for less, apart from... killing i5 sales.
I'm pretty sure the most expensive i3 is not selling well compared to the 3220.
my point is, there is a lot of demand for a cheaper overclockable CPU (the AMD offerings do that, but they have some clear disadvantage), but why would Intel do that, if they can get more money selling the 3570K? or a locked i5.
for a $175 dual core I doubt there is a lot of interest, so you are right about this scenario, but I would like to see a cheap K i3 to compete with the FX 6300 or something (max $150), but Intel doesn't really have good options from $140 up to $ 180...
