Haswell and Broadwell feature a Fully Integrated Voltage Regulator.

Broadwell (previously Rockwell) is the fifth generation of the Intel Core processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication.[2][3][4] Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there were no low-end desktop CPUs based on Broadwell.[5]

Some of the processors based on the Broadwell microarchitecture are marketed as "5th-generation Core" i3, i5 and i7 processors. This moniker is however not used for marketing of the Broadwell-based Celeron, Pentium or Xeon chips. This microarchitecture also introduced the Core M processor branding.

Broadwell is the last Intel platform on which Windows 7 is supported by either Intel or Microsoft; however, third-party hardware vendors have offered limited Windows 7 support on more recent platforms.[6]

Broadwell's H and C variants are used in conjunction with Intel 9 Series chipsets (Z97, H97 and HM97),[7] in addition to retaining backward compatibility with some of the Intel 8 Series chipsets.[citation needed]
