Haswell is a tock, a 22nm new architecture and Broadwell is supposed to be based on Haswell fundamentals, but shrunk to 14nm like a proper “tock”. In case that the Haswell refresh is a tweaked 22nm core, this would mean that after 7 years of execution and billions of investments in cutting edge fabrication processes, Intel would have to slow things down.
It is not certain what would happen to 2015 Skylake, a new 14nm architecture, or the 10nm Skymont that is supposed to be the shrink, but in case Broadwell gets pushed back by a year there is a big possibility that the whole roadmap would slip a year.
When it gets ready the Haswell refresh (possibly a disguise name for Broadwell ed.) is replacing Core i7, Core i5, Core i3, Pentium and Celeron based Haswell chips, some sooner rather than later.
The chipset responsible for Haswell refresh is already branded as Z97 and H97 in desktop versions replacing the Z87 and H87 boards proving that the socket are likely to continue existing at least through 2014. It will be interesting to see the developments and if Broadwell is really delayed or this is just game of words on Intel’s part.
