What is Braswell Processor? (Explained)

What is Braswell Processor?

The term Braswell signifies the name given to the multi-core System on a Chip (SoC) designed by Intel. These are supposed to be the next generation SoCs built on Airmont microarchitecture with industry-leading tri-gate transistors.

Technically, these processors are built on the 14 nm manufacturing process and Complementary Metal Oxide Semiconductor or CMOS technology. These chips support the x86-64 Instruction Set Architecture and 64-bit word size.


  • Braswell processors are multi-core SoCs designed by Intel on the Airmont microarchitecture.
  • These next generation CPUs were designed and first launched by Intel in March 2015, though they were announced a couple of years earlier, in August 2013.
  • These chips are manufactured on a 14 nm process using CMOS technology and come with tri-gate transistors.
  • The clock speed ranges between 1040 MHz and 1600 MHz of these chips, which support a 64-bit word size in the x86-64 Instruction Set Architecture.
  • The Braswell processors are energy efficient and offer a relatively powerful performance when dealing with embedded Linux applications and complex Windows IoT programs.

Understanding Braswell Processor

What is Braswell Processor

The term Braswell is usually the name of the cores of the System on a Chip designed by Intel that were released on March 2015 as the successor to the 22 nm Bay Trail D, Bay Trail I, and Bay Trail M.

Therefore, the Braswell chips are considered to be the die-shrink of Bay Trail CPUs.

The Braswell chips are designed to be used in a diverse range of systems such as:

  • The low-end desktop computer systems
  • The entry level tablets
  • The nettops
  • The netbooks
  • Different ultra-mobile systems
  • The embedded systems

These specific chips are designed on the Airmont microarchitecture and a tri-gate 14 nm manufacturing process.

The improved features and functionalities inside the Braswell chips offer quite high performance overall.

The most significant aspect of these chips is their ability to offer high performance within a specific power envelope. It is due to the specific capabilities of it, which include:

With a core configuration of 2 to 4, the most notable improvement in the design of the Braswell processors is the addition of Gen 8 graphics support.

Braswell vs Haswell

  • The Braswell is a relatively newer technology in comparison to the Haswell, having a release date almost a couple of years later than the latter.
  • The manufacturing process of the Braswell processors is 14 nm, but in comparison, the Haswell processors are built on a 22 nm manufacturing process.
  • The core configuration of the Braswell processors is usually 2 or 4, but in comparison, the range of core configurations of the Haswell processors is much wider, typically ranging between 2 and 18.
  • The Braswell processors support instruction sets such as AES and different extensions of Streaming SIMD Extensions. On the other hand, the Haswell processors follow a wide range of instruction sets and their extensions over and above these.
  • The predecessor of Braswell processors is Bay Trail, while, on the other hand, the predecessor of Haswell processors is Ivy Bridge processors.
  • The successor of the Braswell processors is Apollo Lake, but the successor of the Haswell processor is Broadwell.
