Similarly good questions might include why has Intel used a flawed implementation of PCIe 3.0 in the LGA 2011 CPUs, why does Intel make a huge number of ridiculously similar models (differing by 100MHz or 200MHz is not really differing at all), why does Intel only let us overclock i5s and i7s when lightly threaded performance is generally still key and i3s are no worse at it than i5s (if an ~3GHz i5 can handle things just fine, then I bet that a 5GHz i3 would do similarly well with decent power consumption at a little more than half the price of an i5K), why did Intel use low conductivity paste between the integrated heat spreader and the CPU die of Ivy Bridge CPUs (and a few others historically), and why for so many other screw-ups and screw-yous of AMD, Intel, Nvidia, and so many other companies. They all screw up and do things that can be considered abusive to their customers.
from what i've read so far, ...
intel couldn't (or intentionally didn't, to sell ivb) validate for pcie 3.0 in time for sb-e launch.
intel will never sell an unlocked, <32nm dual core/triple core/core-unlockable cpu. i think they ended with i5 655k. they would do this to protect the unlocked i5 and some lower priced i7s. hell, they even make seperate cpu dies. it isn't about consumer convenience. it is, and always has been, about money. they segment their products in a way that customers
have to pay more to get better
desired performance. the lack of competition in the i5/i7 price segment doesn't help either...
i read somewhere that because of the new 22nm design, newer 3d finfet tech etc
somehow made the cpu more fragile, may be the solder would put more pressure on the cpu. another reason is the one more well-known: to sell ivb without hurting the sb sales while focusing on mobile sector. the ivb cpus have higher tjmax so stock isn't usually the problem. oc is where the heat and temp issues start and intel intentionally sidestepped them with ivb.
intel is in a place where they can
enforce certain things on users as no one's there to challenge them. and they are not diong anything illegal this time e.g. in ivb oc case, intel openly says that they do not cover
component overclocking in their standard warranty (neither does amd).
amd isn't anywhere near where intel is and they don't seem to be chasing intel that way. their biggest asset has been their way of out-strategizing intel like they did by designing the brazos and llano apus. i am expecting them to do the same with trinity and piledriver although it doesn't seem like they've succeeded so far. i really hope they turn around soon.
