Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture). ^[1] Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, ^[2] while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. ^[3] Haswell was the last generation of Intel processor to have socketed processors on mobile. With Haswell, which uses a 22 nm process, ^[4] Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix. Haswell began shipping to manufacturers and OEMs in mid-2013, with its desktop chips officially launched in September 2013.

Haswell CPUs are used in conjunction with the Intel 8 Series chipsets, 9 Series chipsets, and C220 series chipsets.

At least one Haswell-based processor was still being sold in 2022 — the Pentium G3420. ^{[5] [6]} Windows 7 through Windows 10 were released for the Haswell microarchitecture.

Design

The Haswell architecture is specifically designed ^[7] to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node. ^[8]

Haswell has been launched in three major forms: ^[9]

• 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)

Notes

• 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. ^[10] See also Intel HD and Iris Graphics for more details.
• 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.

Performance

Compared to Ivy Bridge:

• Approximately 8% faster vector processing ^[11]
• Up to 5% higher single-threaded performance
• 6% higher multi-threaded performance
• Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge. ^{[11] [12] [13]}
• A 6% increase in sequential CPU performance (eight execution ports per core versus six) ^[11]
• Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000) ^[11]
• Total performance improvement on average is about 3% ^[11]
• Around 15 °C hotter than Ivy Bridge, while clock frequencies of over 4.6 GHz are achievable ^{[14] [15] [16] [17] [18] [19]}

Technology

Features carried over from Ivy Bridge

• 22 nm manufacturing process ^[4]
• 3D Tri-Gate FinFET transistors ^[20]
• Micro-operation cache (Uop Cache) capable of storing 1.5 K micro-operations (approximately 6 KB in size) ^[21]
• 14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss (an approach used in the even earlier Sandy Bridge microarchitecture) ^[21]
• Improve OoO window from 168 to 192 ^[22]
• Queue Allocation from 28/threads to 56
• Mainstream variants are up to quad-core. ^[23]
• Native support for dual-channel DDR3/DDR3L memory, ^[24] with up to 32 GB of RAM on LGA 1150 variants
• 64 KB (32 KB Instruction + 32 KB Data) L1 cache and 256 KB L2 cache per core ^[25]
• A total of 16 PCI Express  3.0 lanes on LGA 1150 variants ^[26]

New features

Haswell featured a Fully Integrated Voltage Regulator.

CPU

• Wider core: ^[27] fourth arithmetic logic unit (ALU), third address generation unit (AGU), ^{[28] [29] [30]} second branch execution unit (BEU), deeper buffers, higher cache bandwidth, improved front-end and memory controller, higher load/store bandwidth.
• New instructions ^[31] (HNI, includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support). ^[32]
• The instruction decode queue, which holds instructions after they have been decoded, is no longer statically partitioned between the two threads that each core can service. ^[21]
• Intel Transactional Synchronization Extensions (TSX) for the Haswell-EX variant. In August 2014 Intel announced that a bug exists in the TSX implementation on the current steppings of Haswell, Haswell-E, Haswell-EP and early Broadwell CPUs, which resulted in disabling the TSX feature on affected CPUs via a microcode update. ^{[33] [34] [35] [36]}
• Fully integrated voltage regulator (FIVR), thereby moving some of the components from motherboard onto the CPU. ^{[37] [38] [39]}
• New advanced power-saving system; due to Haswell's new low-power C6 and C7 sleep states, not all power supply units (PSUs) are suitable for computers with Haswell CPUs. ^{[40] [41]}
• 37, 47, 57 W thermal design power (TDP) mobile processors. ^[23]
• 35, 45, 65, 84, 88, 95 and 130–140 W (high-end, Haswell-E) TDP desktop processors. ^[23]
• 15 W or 11.5W TDP processors for the Ultrabook platform (multi-chip package like Westmere) ^[42] leading to reduced heat, which results in thinner as well as lighter Ultrabooks, but the performance level is slightly lower than the 17 W version. ^[43]

GPU

• Hardware graphics support for Direct3D 11.1 and OpenGL 4.3. ^{[46] [47] [48]} Intel 10.18.14.5180 driver is the last planned driver release on Windows 7/8.1. ^[49]
• 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. ^{[50] [51] [52] [53] [54]}

I/O

• New sockets and chipsets:
  • LGA 1150 for desktops, and rPGA947 and BGA1364 for the mobile market. ^[55]
  • Z97 (performance) and H97 (mainstream) chipsets for the Haswell Refresh and Broadwell, in Q2 2014. ^[56]
  • LGA 2011-v3 with X99 chipset for the enthusiast-class desktop platform Haswell-E. ^[57]
• DDR4 for enterprise/server segments ^[58] and for the Enthusiast-Class Desktop Platform Haswell-E ^[59]
• Variable Base clock (BClk) ^[60] like LGA 2011. ^[61]
• Optional support for Thunderbolt technology and Thunderbolt 2.0 ^{[62] [63]}
• Shrink of the Platform Controller Hub (PCH), from 65 nm to 32 nm. ^[64]

Server processors features

• Haswell-EP variant, released in September 2014, with up to 18 cores and marketed as the Xeon E5-1600 v3 and Xeon E5-2600 v3 series. ^[65]
• Haswell-EX variant, released in May 2015, with 18 cores and functioning TSX. ^{[35] [66] [67]}
• A new cache design.
• Up to 35 MB total unified cache (last level cache, LLC) for Haswell-EP ^[68] and up to 40 MB for Haswell-EX.
• LGA 2011-v3 socket replaces LGA 2011 for the Haswell EP; the new socket has the same number of pins, but it is keyed differently due to electrical incompatibility. ^{[69] [70] [71]}
• The already launched Xeon E3 v3 Haswells will get a refresh in spring 2014, ^[72] together with a refreshed Intel C220 series PCH chipset. ^[73]
• TDP up to 160 W for Haswell-EP. ^[74]
• Haswell-EP models with ten and more cores support cluster on die (COD) operation mode, ^[75] allowing CPU's multiple columns of cores and last level cache (LLC) slices to be logically divided into what is presented as two non-uniform memory access (NUMA) CPUs to the operating system. By keeping data and instructions local to the "partition" of CPU which is processing them, therefore decreasing the LLC access latency, COD brings performance improvements to NUMA-aware operating systems and applications. ^[76]

Haswell Refresh

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. ^[77] 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. ^[78]

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. ^[79] 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. ^[80] 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. ^{[35] [36]}

Windows XP and Vista support

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.^{[ citation needed ]}

^a Some of these configurations could be disabled by the chipset. For example, H-series chipsets disable all PCIe 3.0 lane configurations except 1×16.

^b This feature also requires a chipset that supports VT-d like the Q87 chipset or the X99 chipset.

^c This is called 20th Anniversary Edition and has an unlocked multiplier.

SKU suffixes to denote:

• K – unlocked (adjustable CPU multiplier up to 63x)
  • The Pentium G3258 CPU is unlocked despite not having the K-suffix.
• S – performance-optimized lifestyle (low power with 65 W TDP)
• T – power-optimized lifestyle (ultra low power with 35–45 W TDP)
• R – BGA packaging / High-performance GPU (Iris Pro 5200 (GT3e))
• X – extreme edition (adjustable CPU ratio with no ratio limit)

Server processors

Configurable TDP (cTDP) and Low-Power Mode (LPM) form a design vector where the processor behavior and package TDP are dynamically adjusted to a desired system performance and power envelope. [...] With cTDP, the processor is now capable of altering the maximum sustained power with an alternate guaranteed frequency. Configurable TDP allows operation in situations where extra cooling is available or situations where a cooler and quieter mode of operation is desired.

If the CPU needs to work hard for an extended period of time and the laptop gets warmer, it will slowly ramp down its speed until it's operating at its stated TDP. [...] There are two OEM-configurable "power level" states that define how quick the CPU can be in these situations: PL2 tells the processor how much power it's allowed to use when it needs a short burst of speed, and PL1 defines how quickly the processor can run under sustained load. [...] This is at the heart of what Intel is doing with the Y-series processors: their maximum TDP has been lowered four watts, from 17 to 13. Intel is also validating them for use at two lower PL1 values: 10 watts and 7 watts. This is where the marketing we discussed earlier comes in—rather than keeping these values under the covers as it has so far been content to do, Intel has taken that lowest value, put it on its product pages, and called it SDP.
