According to a report from Fudzilla.com it appears that recent rumors regarding Broadwell are true and that Intel's Broadwell chips will be exclusive to mobile platform while the Haswell refresh will handle the desktop segment of the market.
Intel's Haswell refresh will simply be an improved and optimized Haswell, while the Broadwell chip will be available for tablets, convertibles, two-in-ones and the traditional notebook market. According to the same report, Intel will refresh desktop segment every two years, which is definitely a big slow down from recent roadmaps. This will also give AMD a bit more breathing space in the desktop market.
Skylake is the codename of Intel's next desktop chip and it represents the "tock" in Intel's tick-tock strategy. Since it is based on a new architecture it will also provide much more performance improvement than Broadwell 14nm shrink could ever do. According to recent information, Skylake is also a 14nm chip and should come at some point in 2015.
According to Intel's details, the desktop PC market has significantly slowed down and the average PC is now more than four years old while upgrade cycles are getting longer. These figures should explain Intel's decision to go for the two-year cycle for desktop market segment.
