Haswell is the codename for a processor microarchitecture developed by Intel as the successor to the Ivy Bridge architecture.[1] It uses a 22 nm process.[2] Intel officially announced CPUs with this microarchitecture on June 4, 2013 at Computex Taipei 2013.[3] With Haswell, Intel introduced a low-power processor designed for convertible or "hybrid" Ultrabooks, having the Y suffix. Intel demonstrated a working Haswell chip at the 2011 Intel Developer Forum.[4]

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

Design[edit]

The Haswell architecture is specifically designed[5] to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node.[6]

Haswell has been launched in three major forms:[7]

  1. Desktop version (LGA 1150 socket): Haswell-DT
  2. Mobile/Laptop version (PGA socket): Haswell-MB
  3. 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[edit]

  • ULT = Ultra Low TDP; ULX = Ultra Low eXtreme TDP
  • Only certain quad-core variants and BGA R-series SKUs receive GT3e (Intel Iris Pro 5200) integrated graphics. All other models have GT3 (Intel HD 5000 or Intel Iris 5100), GT2 (Intel HD 4200, 4400, 4600, P4600 or P4700) or GT1 (Intel HD Graphics) integrated graphics.[8] 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[edit]

Compared to Ivy Bridge:

  • Approximately 8% better vector processing performance.[9]
  • Up to 6% faster single-threaded performance.
  • 6% faster multi-threaded performance.
  • Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.[9][10][11]
  • A 6% increase in sequential CPU performance (eight execution ports per core versus six).[9]
  • Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000).[9]
  • Total performance improvement on average is about 3%.[9]
  • Around 15 °C hotter than Ivy Bridge, while clock frequencies of 4.6 GHz are achievable.[12][13][14][15][16][17]

Technology[edit]

Features carried over from Ivy Bridge[edit]

New features[edit]

  • Wider core: fourth ALU, third AGU, second branch prediction unit, deeper buffers, higher cache bandwidth, improved front-end and memory controller
  • New instructions[22] (HNI, includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support).[23]
  • 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.[18]
  • New sockets and chipsets:
    • LGA 1150 for desktops, and rPGA947 and BGA1364 for the mobile market.[24]
    • Z97 (performance) and H97 (mainstream) chipsets for the Haswell Refresh and Broadwell, in Q2 2014.[25]
    • LGA 2011-v3 with X99 chipset for the enthusiast-class desktop platform Haswell-E.[26]
  • 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.[27][28][29][30]
  • Hardware graphics support for Direct3D 11.1 and OpenGL 4.3.[31][32][33]
  • DDR4 for the enterprise/server variant (Haswell-EX and E5v3 SKUs)[34] and for the Enthusiast-Class Desktop Platform Haswell-E[35]
  • Variable Base clock (BClk)[36] like LGA 2011.[37]
  • 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.[38][39][40][41][42]
  • Optional support for Thunderbolt technology and Thunderbolt 2.0[43][44]
  • Fully integrated voltage regulator (FIVR), thereby moving some of the components from motherboard onto the CPU.[45][46][47]
  • 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.[48][49]
  • 37, 47, 57 W thermal design power (TDP) mobile processors.[19]
  • 35, 45, 65, 84, 95 and 130–140 W (high-end, Haswell-E) TDP desktop processors.[19]
  • 15 W TDP processors for the Ultrabook platform (multi-chip package like Westmere)[50] leading to reduced heat, which results in thinner as well as lighter Ultrabooks, but the performance level is lower than the 17 W version.[51]
  • Shrink of the Platform Controller Hub (PCH), from 65 nm to 32 nm.[52]
  • Haswell-EP models with more than 10 cores support cluster on die (COD) operation mode, 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, thus decreasing the LLC access latency, COD brings performance improvements to NUMA-aware operating systems and applications.[53]

Expected server processors features[edit]

  • Release by the end of 2014.[citation needed]
  • Haswell-EP variant, with up to 18 cores and marketed as Xeon E5 2600 v3 series.[56]
  • Haswell-EX variant, with 18–20 cores[citation needed] and functioning TSX.[29]
  • A new cache design.
  • Up to 35 MB total unified cache (Last Level Cache (LLC)) for Haswell-EP[57] 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.[58][59][60]
  • The already launched Xeon E3 v3 Haswells will get a refresh in spring 2014,[61] together with a refreshed Intel C220 series PCH chipset.[62]
  • TDP up to 160 W for Haswell-EP.[63]

Haswell Refresh[edit]

According to Intel roadmaps, Broadwell will be released in first half of 2015, thus 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.[64] Haswell Refresh CPUs are supported by Intel's new 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.[65]

The CPUs codenamed Devil's Canyon, covering the i5 and i7 K-series stock keeping units (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.[66] 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.[67] 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.[29][30]

Intel also released the Pentium Anniversary Edition (Pentium G3258), an unlocked and highly overclockable processor that marks 20 years of "Pentium" as a brand.[68]

List of Haswell processors[edit]

Desktop processors[edit]

Intel Haswell i7-4771 CPU, placed atop its original packaging that contains an OEM fan-cooled heatsink
  • All models support: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, F16C, BMI1 (Bit Manipulation Instructions1)+BMI2, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, and Smart Cache.
    • Core i3, i5 and i7 support AVX, AVX2, FMA3 and AES-NI.[69]
    • Core i3 and i7, as well as the Core i5-4570T and i5-4570TE, support Hyper-threading (HT).[69]
    • Core i5 and i7 support Turbo Boost 2.0.[69]
    • Although it was initially supported on selected models, since August 2014 desktop variants no longer support TSX due to a bug that was discovered in its implementation; as a workaround, a microcode update disabled the TSX feature.[27][29][30][69]
    • SKUs below 45xx as well as R-series and K-series SKUs do not support Trusted Execution Technology or vPro.[69]
    • Intel VT-d, which is Intel's IOMMU, is supported on all i5 and i7 "non-K" SKUs and on most, but not all, i5 and i7 "K" SKUs. Two "K" SKUs without VT-d support are the i5-4670K and i7-4770K.[69][70][71] Support for VT-d requires the chipset and motherboard to also support VT-d.
    • Models i5-4690K and i7-4790K, codenamed Devil's Canyon, have a better internal thermal grease to help heat escape and an improved internal voltage regulator ("FIVR"), to help deliver clean power in extreme situations like overclocking.
  • Transistors: 1.4 billion
  • Die size: 177 mm2
  • Intel HD and Iris Graphics in following variants:
    • R-series desktop processors feature Intel Iris Pro 5200 graphics (GT3e).[72]
    • All other currently known i3, i5 and i7 desktop processors include Intel HD 4600 graphics (GT2).[73]
    • The exceptions are processors 41xxx, which include HD 4400 graphics (GT2).
    • Celeron and Pentium processors contain Intel HD Graphics (GT1).
  • Pentium G3258 (Pentium 20th Anniversary Edition) has an unlocked multiplier.

[...] 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."
