In the second quarter 2014 will be released new models of Intel Haswell generation, from topical solutions it differ only by increased clock speed of computing and graphics systems. They will be accompanied by motherboards based on chipset ninth series, but any new Haswell processor will work in conjunction with the eighth series.
Broadwell generation processors , will be replace Haswell in the future, will only work in motherboards based on chipset ninth series. As explained associate problems with backward compatibility arise due to regular changes in the mechanisms of new processors power .
Haswell processor recommended the use of power supply capable of delivering current of 0.05 A bus-12V2, and Broadwell require changes already in the motherboard power system . In particular, the compound V_PROC_IO needs a source with a voltage of 1.05 V, also added a new bus supply VCCST and version will be made in the topology THRMTRIP.
