Intel Haswell to feature on-die voltage regulator

FUD Zilla reports Intel's Haswell processor will have an on-die voltage regulator:
The job of a component named FIVR (Fully integrated voltage regulator) is to integrate legacy power delivery onto the processor package and die. Current processors in the market are working via PLL voltage regulators and even thou we don’t understand this part enough to brag about it, we know that Fully integrated voltage regulator will enable designs with less components and save manufacturers a few cents / bucks.

Intel clams that getting the FIVR on die / package will greatly simplify a platform power design and that it can consolidate 5 platform voltage regulators to just one. The Haswell will now come with input voltage regulator that takes to FIVR and this should offer a better arch flexibility and finer grain on die processor delivery control.
