Haswell (microarchitecture)#Mobile

The Haswell architecture is specifically designed{{cite web|url=http://www.pcper.com/reviews/Processors/IDF-2012-Intel-Haswell-Architecture-Revealed |title=IDF 2012: Intel Haswell Architecture Revealed |publisher = PC Perspective |last=Shrout |first=Ryan|date=11 September 2012 }} to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node.{{cite web|url=http://www.theinquirer.net/inquirer/news/2206077/idf-intel-says-haswell-wont-use-ivy-bridge-transistors |archive-url=https://web.archive.org/web/20120920221812/http://www.theinquirer.net/inquirer/news/2206077/idf-intel-says-haswell-wont-use-ivy-bridge-transistors |url-status=unfit |archive-date=September 20, 2012 |title=IDF: Intel says Haswell won't use Ivy Bridge transistors |publisher=The Inquirer |date=2012-09-17 |access-date=2013-10-12}}

Haswell has been launched in three major forms:{{cite web|url=http://www.techpowerup.com/177817/Intel-Haswell-and-Broadwell-Silicon-Variants-Detailed.html |title=Intel Haswell and Broadwell Silicon Variants Detailed |publisher=techPowerUp |date=2012-12-26 |access-date=2013-10-12}}

• Desktop version (LGA 1150 socket and the LGA 2011-v3 socket): Haswell-DT
• Mobile/Laptop version (PGA socket): Haswell-MB
• BGA version:
• 47 W and 57 W TDP classes: Haswell-H (for "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats)
• 13.5 W and 15 W TDP classes (MCP): Haswell-ULT (for Intel's UltraBook platform)
• 10 W TDP class (SoC): Haswell-ULX (for tablets and certain UltraBook-class implementations)

• ULT = Ultra Low TDP; ULX = Ultra Low eXtreme TDP
• Only certain quad-core variants and BGA R-series stock keeping units (SKUs) receive GT3e (Intel Iris Pro 5200) integrated graphics. All other models have GT3 (Intel HD 5000 or Iris Pro 5100), GT2 (Intel HD 4200, 4400, 4600, P4600 or P4700) or GT1 (Intel HD Graphics) integrated graphics.{{cite web

• Due to the low power requirements of tablet and Ultrabook platforms, Haswell-ULT and Haswell-ULX are only available in dual-core configurations. All other versions come as dual- or quad-core variants.

Compared to Ivy Bridge:

• Approximately 8% faster vector processing{{cite web|last=Shvets|first=Gennadiy|title=Intel Core i5-3570K vs i5-4670K|url=http://www.cpu-world.com/Compare/579/Intel_Core_i5_i5-3570K_vs_Intel_Core_i5_i5-4670K.html|access-date=23 July 2013|date=9 July 2013}}
• Up to 5% higher single-threaded performance

• Four versions of the integrated GPU: GT1, GT2, GT3 and GT3e, where GT3 version has 40 execution units (EUs). Haswell's predecessor, Ivy Bridge, has a maximum of 16 EUs. GT3e version with 40 EUs and on-package 128 MB of embedded DRAM (eDRAM), called Crystalwell, is available only in mobile H-SKUs and desktop (BGA-only) R-SKUs. Effectively, this eDRAM is a Level 4 cache; it is shared dynamically between the on-die GPU and CPU, and serving as a victim cache to the CPU's Level 3 cache.{{cite web

Around the middle of 2014, Intel released a refresh of Haswell, simply titled Haswell Refresh. When compared to the original Haswell CPUs lineup, Haswell Refresh CPUs offer a modest increase in clock frequencies, usually of 100 MHz.{{cite web

| author = Ian Cutress | publisher = AnandTech

}} Haswell Refresh CPUs are supported by Intel's 9 Series chipsets (Z97 and H97, codenamed Wildcat Point), while motherboards with 8 Series chipsets (codenamed Lynx Point) usually require a BIOS update to support Haswell Refresh CPUs.{{cite web|url=http://www.asus.com/Motherboards/Z87DELUXE/HelpDesk_CPU/ |title=Motherboards — Z87-DELUXE |publisher=ASUS |access-date=2014-07-26}}

The CPUs codenamed Devil's Canyon, covering the i5 and i7 K-series SKUs, employ a new and improved thermal interface material (TIM) called next-generation polymer thermal interface material (NGPTIM). This improved TIM reduces the CPU's operating temperatures and improves the overclocking potential, as something that had been problematic since the introduction of Ivy Bridge.{{cite web

}} Other changes for the Devil's Canyon CPUs include a TDP increase to 88 W, additional decoupling capacitors to help smooth out the outputs from the fully integrated voltage regulator (FIVR), and support for the VT-d that was previously limited to non-K-series SKUs.{{cite news |last=Cutress |first=Ian |date=July 11, 2014 |title=Devil's Canyon Review: Intel Core i7-4790K and i5-4690K |url=http://www.anandtech.com/show/8227/devils-canyon-review-intel-core-i7-4790k-and-i5-4690k |newspaper=AnandTech |page=1 |access-date=August 26, 2014}} 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.

While Ivy Bridge is the last Intel processor to fully support all versions of Windows XP, Haswell includes limited driver support for certain XP editions such as POSReady2009. People have modified the graphics driver for these versions to adapt to normal Windows XP to varying degrees of success.

Windows Vista support is also dropped with this processor as well. People who have installed x64 version of Vista have reported various problems such as services not starting automatically. The KB4493471 update (officially intended only for Windows Server 2008, but can be installed on Vista) contains a HAL driver that allegedly fixes these issues; however, upon several tests it's been confirmed - it doesn't fix any of the issues. Windows XP and earlier, and all x86 versions and editions of Vista are unaffected by this bug.{{cn|date=July 2023}}

• SKUs below 45xx as well as R-series and K-series SKUs do not support Trusted Execution Technology or vPro.
