'''Broadwell''' ('''BDW''') is [[Intel]]'s  [[microarchitecture]] based on the [[14 nm process]] for mobile, desktops, and servers. Introduced in early 2015, Broadwell is a [[process shrink]] of {{\\|Haswell}} which introduced several enhancements. Broadwell is named after [[wikipedia:Broadwell, Illinois|Broadwell, Illinois]].
 
  
For desktop and mobile, Broadwell is branded as 5th Generation Intel {{intel|Core}} processors. For server class processors, Intel branded it as {{intel|Xeon E3|Xeon E3 v4}}, {{intel|Xeon E5|Xeon E5 v4}}, and {{intel|Xeon E7|Xeon E7 v4}}.

Broadwell is designed to be manufactured using [[14 nm]] Tri-gate [[FinFET]] transistors. This correlates to 8 nm Fin width and a 42 nm Fin pitch (shown below). SRAM cell is at 0.0706 µm² and 0.0499 µm² for high performance and high density.

==== New instructions ====
 
Broadwell introduced a number of new instructions:
 
* {{x86|RDSEED|<code>RDSEED</code>}} - Generates 16, 32 or 64 bit random numbers seeds ([[NIST SP 800-90B]] & [[NIST SP 800-90C]])
 
* {{x86|ADCX|<code>ADCX</code>}} - Arbitrary precision integer operations
 
* {{x86|PREFETCHW|<code>PREFETCHW</code>}} - Prefetch data into caches, hinting a write is expected in the future
 
* {{x86|SMAP|<code>SMAP</code>}} - Supervisor Mode Access Prevention
