Tick–tock model

Tick-Tock modelTick-Tocktick–tock
It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication.
Every "tick" represented a shrinking of the process technology of the previous microarchitecture (sometimes introducing new instructions, as with Broadwell, released in late 2014) and every "tock" designated a new microarchitecture.

Transactional Synchronization Extensions

TSXIntel TSX-NIIntel TSX
In August 2014, Intel announced a bug in the TSX implementation on current steppings of Haswell, Haswell-E, Haswell-EP and early Broadwell CPUs, which resulted in disabling the TSX feature on affected CPUs via a microcode update.

Broadwell is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture.
In September 2013, Intel demonstrated an Ultrabook laptop that used a 14 nm Broadwell CPU, and Intel CEO Brian Krzanich said, "[CPU] will be shipping by the end of this year."

Supervisor Mode Access Prevention

SMAP
Supervisor Mode Access Prevention (SMAP) is a feature of some CPU implementations such as the Intel Broadwell microarchitecture that allows supervisor mode programs to optionally set user-space memory mappings so that access to those mappings from supervisor mode will cause a trap.

Platform Controller Hub

PCHLynx PointCougar Point
Beginning with ultra-low-power Broadwells and continuing with mobile Skylake processors, Intel incorporated the clock, PCI controller, and southbridge IO controllers into the CPU package, eliminating the PCH for a system on a chip (SOC) design.
