Broadwell is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's principle as the next step in semiconductor fabrication. Like some of the previous tick-tock iterations, Broadwell will not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there will be no low-end desktop CPUs based on Broadwell.
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's H and C variants will be used in conjunction with Intel 9 Series chipsets (Z97, H97 and HM97), in addition to retaining backward compatibility with some of the Intel 8 Series chipsets.
Broadwell has been launched in three major variants:
Broadwell introduces some instruction set architecture extensions:
Broadwell's Intel Quick Sync Video hardware video decoder adds VP8 hardware decoding and encoding support. It adds VP9 and HEVC 10-bit decoding support through the integrated GPU. Also, it will have two independent bit stream decoder (BSD) rings to process video commands on GT3 GPUs; this will allow one BSD ring to process decoding and the other BSD ring to process encoding at the same time.
Broadwell's integrated GPU supports on Windows Direct3D 11.2, OpenGL 4.4 (OpenGL 4.5 on Linux) and OpenCL 2.0. However, it is marketed as Direct3D-12-ready. Broadwell-E introduced Intel Turbo Boost Max Technology 3.0.
