The original post did refer to Sandy Bridge and unlocked multiplier based CPUs, all of which now carry a price premium. You really never know if this is just the start of locking down budget chips or not- or if AMD will follow suit. What does look certain is that we will never see something like a Celeron 300A or Pentium D 805 out of Intel in the foreseeable future.
Intel chips as expensive as they are now and then wanting to charge extra for you to have the ability to really tweak it I believe is going to bite them in the OC'ing market sooner or later.
AMD being more friendly towards this end with the BE chips and not appearing to worry so much about unlocking cores has helped them to reclaim a great deal of this market share. For now AMD is riding the wave and reaping the benefits - I know they could suddenly bring this to a halt but I just can't see them doing that right away or even in the near future since the way their chips are being made and selling is a benefit for them.
Yes, taking a budget chip and making it go faster/unlocking cores means they won't make as much but AMD's efforts with the Phenom II chips are paying off and they know it. The more of the market share they do get, the better they'll do since you'd need an AMD based board to go with it and CPU upgrades to it will also be AMD based = More $$.
Many of us are asking if Bulldozer will be based on the current AM3 socket and so far, the answer many are giving is "No" but even with that going on, the current socket will continue to sell chips for them with each new offering based on it and will do so for at least sometime to come.
It amounts to getting their "Foot in the door" with their chips with new customers = A larger market share and also providing a good value to keep those of us running AMD now from jumping over to Intel.
Right or wrong, that's how I see it for now.
