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]
