Based on available at the Italian site Bits & Chips information significant architectural changes in Skylake greatly complicated the preparation for the announcement of these processors. Perfecting processors may take time, and it is an architectural nuance rather than a problem with the 14-nm technology. But in terms of performance growth processors Skylake may differ from Broadwell as Conroe at the time differed from Prescott.
By the way, the same resource in the last year reportedthat Intel engineers based in Israel , engaged in the development Skylake, trying to insist on the use of solder to attach the heat spreader to the processor chip. This would improve the thermal conditions of the processors. It is known that for some time now Intel prefers to save on mass models, providing the bulk of its processors less efficient thermal interface. For the correction of this problem in the past year were even released two processor series Devil's Canyon, which is an improved version Haswell with a decent thermal interface and enhanced power system.
In addition, this same source revealed that motherboard manufacturers have brought to CeBIT 2015 a sufficient number of products based on chipset Intel Z170, which is required to work with processors Skylake by LGA 1151.
