Haswell is a (probably) ~1.6 Billion transistor chip that obviously costs more than a SoC that is really designed for tablets. Interesting then that a ~1.6 Billion transistor chip that includes similar functionality to the SoC uses about the same amount of power as that tablet SoC while including vastly more performance.
If you want cheap, Atoms are already out now that are quite cost competitive with ARM chips, and 22nm Atoms will be out next year.
Oh and as for "release dates" the Exynos has just barely begun to reach the market and Haswell will be out and about at around the same time that most Cortex A-15s really come into the market as well. Considering I've had to listen to "A15 will kill Intel!!!!" for over 2 years as if they were already coming out of faucets like water, I'm not too worried about part availability.
So here we are in the ARM vs. Intel Evolution:
2008: ARM is superior, Intel can NEVER scale its power consumption down below 100 watts!!
2009-2010: ARM is still superior! Atom sucks at performance and uses 10 WHOLE WATTS, thats more than 10X ARM! The Cortex A9 will annihilate Intel!
2011: ARM performance dominance is just around the corner! Ignore those useless benchmarks of Cortex A9 vs. Atom! So what if Atom has higher performance, IT SUCKS DOWN MORE POWER AND POWER CONSUMPTION IS ALL THAT MATTERS!
2012: Medfield sucks! Who cares if it gets better battery life than a dual-core 28nm Krait when put into Motorala Razers with the exact same! See, we have benchmarks where the higher-clocked Krait gets 10% better performance (in some benchmarks while losing in others that we ignore)! WHO CARES THAT ATOM IS MORE POWER EFFICIENT THE ONLY THING THAT MATTERS IS MORE PERFORMANCE!
INTEL IS STILL OVERPRICED EVEN THOUGH THE RAZER I AND RAZER M HAVE THE SAME PRICE!
2013: Uh... at least ARMs are cheap when you intentionally compare chips desiged for cellphones to Intel's desktop chips and pretend that Atom doesn't exist. ARM WILL DESTROY INTEL!
