Broadwell (microarchitecture)

Broadwell 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. 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.

Intel Core processors based on the Broadwell microarchitecture are marketed as fifth-generation Core i3, i5 and i7 processors. 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.

Design and variants

Broadwell has been launched in three major variants:

Core

Core may refer to:

Computers and technology

Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

Core (anatomy)

In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck.

Muscles

Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius.

Functions of the core

The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.).

Continence is the ability to withhold bowel movements, and urinary stress incontinence (the lack of bladder control due to pelvic floor dysfunction) can result from weak core musculature.
