What is Haswell Processor?
Haswell refers to the codename of the microarchitecture of the Intel processors belonging to the 4th generation I-series. It is the successor of Ivy Bridge and is built on a 22 nm manufacturing process with the FinFET 3D or non-planar transistors and is part of the Intel 8 and 9 series chipsets.
- The Haswell processors offer quicker vector processing and better single-threaded, multi-threaded, and graphics performance.
- These processors are good to use in desktop and laptop computers and the low-power variants in tablets, ultrabooks, mini computers and in the Intel Next Unit of Computing.
- The different variants of the Intel Haswell processors are the Haswell DT, MB, H, ULT, ULX, EP, EX, and the Haswell E.
- There are different types of sockets used in a Haswell processor such as LGA 1150, LGA 2011-v3, PGA and BGA sockets meant to be used in specific types of computers.
- The Haswell processors come with a lot of improved and additional features in comparison to its successor as well as significant changes made in the Gpu and cache memory.
Understanding Haswell Processor
The Haswell microarchitecture of Intel is based on the 22 nm manufacturing technology and was introduced for the first time in 2013.
It is the 22 nm manufacturing process of the Intel Haswell architecture that optimizes its power savings and offers reasonably good performance benefits.
Some of the performance benefits offered in comparison to Ivy Bridge are:
- About 8% quicker vector processing
- Up to 5% superior single-threaded performance
- Up to 6% better multi-threaded performance
- About 20% better graphics performance and
- About 3% overall performance improvement.
Suitable to be used in desktop and laptop computers, the desktop variants of Haswell CPUs come in quad-core and dual-core variety.
The low-power versions of the Haswell processors can be used in ultrabooks, tablets and even in the Intel Next Unit of Computing or NUC mini-PCs.
History and Design
Official announcement of processors with Haswell microarchitecture was made by Intel at Computex Taipei 2013 on June 4, 2013.
However, a fully functional Haswell CPU was demonstrated at the Intel Developer Forum in 2011.
The Intel Haswell processors are used in combination with different types of Intel chipsets such as:
- The Intel 8 Series chipsets
- The Intel 9 Series chipsets and
- The Intel C220 series chipsets.
The 22 nanometer photolithographic manufacturing process of Haswell also brought in low power CPUs for hybrid or convertible ultrabooks that were denoted by the U suffix.
The processor architecture uses the non-planar or 3D FinFET transistor design which makes these processors much more power efficient and improves the performance.
In fact, when you compare the Intel Haswell processors with its technological predecessor, Ivy Bridge, it offers 6% better performance in sequential processing while running only 15oC hotter.
In the Haswell microarchitecture, all the clock domains are derived from the base clock speed or BCLK, which is also referred to as DMICLK.
The voltage is controlled in the Haswell processors by the FIVR based architecture.
Here, the voltage arrives through the VCCin input into the CPU from the motherboard and then to the voltage regulator.
All the different voltage planes are derived internally from there which includes VRING, VCORE, and VSA.
The memory voltage is however supplied from the motherboard to its rail.
As for overclocking, there is a Coarsed BCLK ratio provided by Haswell which can be 100 MHz, 125 MHz, or 166.66 MHz.
The chipset generates the clock internally but motherboard Original Design Manufacturers or ODMs can also generate it separately as well.
Every single BCLK from the PCH or Platform Controller Hub is provided for in < 1 MHz steps. Depending on the different Coarsed BCLK ratio, it may work out as follows:
- 100 MHz ± 5-7% PEG/DMI @ 5:5
- 125 MHz ±5-7% PEG/DMI @ 5:4 and
- 166.66 MHz ±5-7% @ 5:3.
In practice, however, it is quite different and is typically restricted by the DMI PLL or the PCI Express interface.
The Intel Haswell processors come in different codenames. Here is the list of the codenames along with their abbreviations and targets:
- The Haswell DT, commonly referred to as HSW-DT and especially targeted for the desktops
- The Haswell MB, commonly referred to as HSW-MB and especially targeted for the mobiles and laptops
- The Haswell H, commonly referred to as HSW-H and especially targeted for the All-in-ones
- The Haswell ULT, commonly referred to as HSW-ULT and especially targeted for the ultrabooks and other mobile computing devices
- The Haswell ULX, commonly referred to as HSW-ULX and especially targeted for the tablets and ultrabooks
- The Haswell EP, commonly referred to as HSW-EP and especially targeted for the Xeon chips
- The Haswell EX, commonly referred to as HSW-EX and especially targeted for the Xeon chips and
- The Haswell E, commonly referred to as HSW-E and especially targeted for the High-End Desktops or HEDTs.
The Haswell processors come in different types of sockets such as:
- Land Grid Array or LGA 1150 and LGA 2011-v3 in the desktop variant
- Pin Grid Array or PGA sockets for a few specific types of laptop and mobile processors and
- Ball Grid Array or BGA sockets for Mini-ITX motherboards, All-in-One PCs, ultrabook laptops and tablets.
There are a few specific features of the Haswell processor that resembles that of the Ivy Bridge. These carried over features are:
- The 22 nanometer manufacturing process

- L1d and L2 cache bandwidth doubled
- 2 MB pages support by the STLB and
- Widened scheduler.
There are also a few changes made in the Central Processing Unit and the Graphics Processing Unit of the Intel Haswell processors.
The changes made in the CPU allow the Haswell processors to handle several general purpose instructions with an output of 4 ops/cycle.
Its predecessor could handle only CLC or Custom Loop Configurations, NOP or no Operations, and a few vector MOVs and a few zeroing instructions such as XOR, SUB, and vector analogs.
Some of the changes made in the CPU include:
- Bit forms of MOVSX and MOVZX 4 op/cycle output for 8->32, 8->64 and 16->64
- Several Arithmetic Logic Unit operations 4 op/cycle output for General Purpose registers for OR, XOR, NEG, ADD, SUB, NOT, AND, CMP, and others
- Variable rotates and shifts such as SHL r32 and CL latency augmented from 1 to 2 cycles
- Variable SHLD or SHRD increased from 2 to 4 cycles
- REP MOVS copy speed is doubled up to about 52 bytes/cycle and
- REP STOS fill speed is doubled up to about 30 bytes/cycle.
The graphics performance of the Intel Haswell processor is quite good and it is due to the hardware support for OpenGL 4.3, OpenCL 1.2, and Direct3D 11.1.
There are 4 versions of graphics chip integrated into the Intel Haswell processor depending on its specific model such as:
- GT3 and
Out of these, the GT3 version comes with 40 Execution Units as compared to 16 of such units present in its predecessor, Ivy Bridge.
The GT3e version, on the other hand, also comes with 40 EUs as well as an on-package of eDRAM or embedded Dynamic Random Access Memory.
However, these are called Crystalwell and are available only in desktop BGA-only R-SKUs and mobile H-SKUs.
The eDRAM acts effectively as a Level 4 cache memory and is shared between the CPU and the on-die GPU dynamically.
It also acts as a victim cache to the L3 cache memory of the CPU.
Talking about the cache memory, the memory hierarchy in Haswell processors has also undergone some significant changes with respect to its predecessor.
The bandwidth of the cache for load and store has been doubled from 32 B/cycle and 16 B/cycle respectively.
The improvements are quite significant which supports the new gather instructions as well as the transactional memory.
Add to that, the new port 7 includes an address generation.
With the changes made in the cache hierarchy of the Intel Haswell processor, it has improved its functionality and each of them is as follows.
The Level 1 instruction cache:
- Is 32 KB 8-way set associative
- Supports write back policy
- Has 64 B line size and
- Is shared by the two threads per core.
The Level 1 data cache:
- Is 32 KB 8-way set associative
- Supports write back policy
- Has 64 B line size
- Has 64 Bytes/cycle load bandwidth
- Has 32 Bytes/cycle store bandwidth
- Supports 4 cycles for quickest load-to-use and
- Is shared by the two threads per core.
The Level 2 cache:
- Is unified 256 KB 8-way set associative
- Has 64 B/cycle bandwidth
- Supports 11 cycles for quickest load-to-use and
- Supports write back policy.
The Level 3 cache:
- Is 1.5 MB to 3 MB in size
- Supports write back policy and
- Is per core.
The Level 4 cache:
- Is 128 MB in size
- Is available per package and
- Is available only on the Iris Pro GPUs.
And as for the Haswell TLB or the Translation Lookaside Buffer, there is a dedicated level one TLB for data cache and another for instruction cache.
Add to that, there is also a combined second level TLB. The breakup is as follows.
For 4KB page translations, the iTLB is 4-way set associative and divided between the two threads in a dynamic partition. It supports 128 entries.
And, for 2 MB or 4 MB page translations, the iTLB is fully associative and duplicated for each thread. It supports 8 entries.
As for the dTLB, for 4KB page translations, it is 4-way set associative and divided between the two threads in a fixed partition. It supports 64 entries.
And, for 2 MB or 4 MB page translations, the dTLB is 4-way set associative and supports 32 entries.
However, for 1 GB page translations, the dTLB is 4-way set associative and supports only 4 entries.
Finally, for the STLB, for 4 KB + 2 M page translations, it is a shared, 8-way set associative and supports 1024 entries.
Different models of the Intel Haswell processors come with different types of die such as:
- For the dual-core GT2, it has 960,000,000 transistors in a 131 mm² die size
