Haswell is the code name of a processor micro- architecture from the chip manufacturer Intel , which appeared as the successor to the Ivy Bridge architecture in the 2nd quarter of 2013. Like Ivy Bridge, Haswell is also based on the 22 nm process. The integrated GPU also supports DirectX 11.1 and OpenGL 4.0. Mainboards with socket 1150 and one of the new 80s chipsets are required. For the Haswell processors of the second generation, also called Haswell Refresh, the chipsets of the 90 series are intended.

The Haswell processors were officially presented on June 1, 2013, a few days before the start of the Computex IT trade fair . However, individual dealers in China and other parts of Asia began selling Haswell processors and LGA1150 mainboards earlier.

The code name was derived from the town of Haswell in the US state of Colorado .

design

Haswell has been specially optimized for energy efficiency and performance in order to take advantage of the new FinFET transistors that were introduced when switching to the 22 nm manufacturing process.

Chipset for Haswell processors

Haswell processors are not compatible with the chipsets for the Ivy Bridge processors. In addition, Intel and Haswell are introducing new chipsets with additional features, such as more USB 3.0 interfaces.

Explanations

Haswell came up with a so-called FIVR .

• ULT = Ultra Low Thermal Design Power ; ULX = Ultra Low eXtreme TDP.
• Only certain BGA versions will have a GT3 (Intel HD 5000, Intel Iris 5100) or GT3e (Intel Iris Pro 5200) integrated graphics unit. All other models receive the GT2 (Intel HD 4X00) integrated graphics unit. For more information, see Intel HD Graphics .
• Since ultrabooks and tablets require low energy consumption, Haswell ULT and Haswell ULX processors will only be available in a dual-core version. All other versions are dual or quad core models.

power

Compared to Ivy Bridge , Haswell has approximately 8% more vector processing power and up to 6% better single-thread performance. In addition, a Haswell processor consumes approx. 8% less power under load than a comparable Ivy Bridge model. In addition, an improvement in sequential CPU performance of 6% compared to Ivy Bridge can be recorded (instead of 6 now 8 execution ports per core). The main optimization was carried out with the integrated graphics unit, which achieved a 20% increase in performance compared to the predecessor Intel HD 4000 (Haswell HD 4600 vs. Ivy Bridge HD 4000).
