Very disappointing weekend for me hearing about Haswell. Moore's law looks dead and I'm not sure that's as much due to technology limitations as a conscious choice at Intel about priorities. Everything is about low-power now, and I think we're paying for that as enthusiasts. I'd rather go back to 32nm if it means having a more enthusiast-aimed chip with higher OCs and, ironically enough, less heat. The architecture improvements will now always be given mutually with lower power requirements, thus reducing the ability to OC the chip and maximize the capability of the architecture for speed. Sacrificing speed for efficiency. My computer is like an exotic performance car to me, and I am willing to sacrifice energy use for speed because a computer is the most important tool I have, I don't want the CPU equivalent of a i-4 hybrid civic, and am feeling forced into that. Desktop architecture and mobile architecture imho needs to be separated. Desktops should follow enthusiast/sever development closer, and leave this 22nm/16nm/12nm low voltage stuff to a separate line of chips. Let them actually develop their Atom line and leave the quad core desktops alone.
And just as the OP has stated, I think that the Bloomfield/Sandy Bridge era will become legendary in CPU history, offering massive performance leap that is still relevant and competitive with today's chips. I love the 2600k in my system, its a hero chip, and I don't plan on changing it up until Intel gives me another chip to get excited about.
And just so you know we're not alone:
