We will soon see if AtenRa's prediction that i5k sales will plummet is true or not Will keep a close eye on Intel's reported desktop CPU ASPs.
I have also said this,
I believe Intel will not have any problem to allow this only on the very expensive Z170 motherboard models.
This way only overclockers will bother to OC a Pentium or Core i3/5 and normal users will opt for a cheaper motherboard to pair it with a locked Core i5 or even Core i7.
If you need a $150-200+ motherboard to just OC a $70 CPU then for the same price most users will go for a $50 motherboard + $190-200 Core i5.
And judging by the results of this one,
I can tell you right now i would easily recommend a H110 + Core i5 6400 over Z170 + Core i3 6100 OC (for budget constrained users). Especially for gaming.
But what happens if you can OC the Core i3 6100/6300 on a H110 board ??
I will immediately recommend the H110+ Core i3 OC for low budget gaming systems over the Core i5. The only Core i5 to be recommended will be the K model for the 1% of users that will spend 300-400 for a CPU + Mobo.
And let me explain to you why Intel dont want OCable H110.
H110 + OC Core i5 6400 =
Lowest margin products of each family (chipset and CPUs)
If the Core i5 6400 can reach 4.4GHz on the H110 motherboards, Z170 + Core i5 6600K sales will completely plummet.
Z170 + Core i5 6600K =
Highest margin products of each Family.
In 2011 the best selling Intel CPU was the Core i5 2500K, the highest margin Core i5. In 2016 it will be the Core i5 6400, the lowest margin Core i5. It will also destroy the Core i3 sales because people will choose only two CPUs.
1. Pentium G4400 ($65) OCed to 4.4GHz + H110
2. Core i5 6400 ($190) OCed to 4.4GHz + H110
Nobody was recommending Haswell Core i3 over the Pentium G3258 or entry Core i5s in 2014/5. Same will happen in 2016 if H110 will receive an OC bios.
