BAD HARDWARE WEEK

 Not compatible, in small quantities and thus expensive, VERY EXPENSIVE.


While Haswell and the Broadwell-powered 9-series will share the LGA1150 socket, there will be a number of slight changes between the two. The most notable changes are in the V_PROC_IO connection, as it requires a 1.05V power source, VCCST, because of a new type of power supply required, and to THRMTRIP because of a slightly different chip topology. This presents a number of backwards compatibility issues, and means that only motherboards that support refreshed Haswell will be compatible with the 9-series Broadwell chips. HASWELL REFRESH IS LOWER POWER HASWELL VERSION. AND BETWEEN NEW GENERATION AT INTEL WE HAVE NOW 3 YEARS. THAT MEANS THE NEXT ONE 11nm IS ONLY BY THE  2017 END .
