Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is simply a die shrink/tick of Sandy-Bridge-microarchitecture).
In 2014, Intel created a "tock refresh" of a tock in the form of a smaller update to the microarchitecture not considered a new generation in and of itself.

Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is simply a die shrink/tick of Sandy-Bridge-microarchitecture).
For example, Intel incorporates multiple AGUs into its Sandy Bridge and Haswell microarchitectures, which increase bandwidth of the CPU memory subsystem by allowing multiple memory-access instructions to be executed in parallel.

Transactional Synchronization Extensions

TSXIntel TSX-NIIntel TSX
TSX was another feature brought over from the non-K-series SKUs, until August 2014 when a microcode update disabled TSX due to a bug that was discovered in its implementation.
TSX was documented by Intel in February 2012, and debuted in June 2013 on selected Intel microprocessors based on the Haswell microarchitecture.

LGA 2011

LGA 2011-v3 (Socket R3, also referred to as LGA 2011-3) is another updated generation of the socket, used for Haswell-E and Haswell-EP CPUs, which were released in August and September 2014, respectively.

Voltage regulator module

fully integrated voltage regulatorvoltage regulatorsIntegrated voltage regulator
Some processors, such as Intel Haswell CPUs, feature voltage regulation components on the same package (or die) as the CPU, instead of having a VRM as part of the motherboard; such a design brings certain levels of simplification to complex voltage regulation involving numerous CPU supply voltages and dynamic powering up and down of various areas of a CPU.

EDRAM
