Haswell In comparison with a pin

Haswell is the codename for a processor microarchitecture by chipmaker Intel, which was planned as the successor to the Ivy Bridge architecture for the second quarter of 2013. As Ivy Bridge and Haswell is based on the 22nm process. The integrated GPU can also support DirectX 11.1 and OpenGL 4.0. There are motherboards needed with base 1150. The new chipsets are denominated in 80 denominations.

Officially, the Haswell processors have been introduced on June 1, 2013, a few days before the IT show Computex. Individual retailers in China and other parts of Asia, however, began earlier with the sale of Haswell processors and LGA1150 motherboards.

Design

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

Haswell was released in three versions:

• 47 W and 57 W TDP: Haswell -H ( for "All -in-one " systems, Mini - ITX Motherboards and other Motherboards small form factor)
• 13.5 W and 15 W TDP (MCM ): Haswell ULT ( for Intel's Ultrabook platform)
• 10 W TDP (SoC ): Haswell ULX ( for tablet computers and dedicated Ultrabook implementations)

Notes

• Only certain BGA versions of a GT3 (Intel HD 5000, Intel Iris 5100 ) or GT3e ( Iris Intel Pro 5200 ) obtained integrated graphics unit. All other models get the GT2 (Intel HD 4X00 ) integrated graphics unit. For more information about offers Intel HD Graphics.
• As ultrabooks and tablets require low energy consumption, Haswell and Haswell ULT - ULX - processors will be available in a dual-core variant. All other versions are dual-or quad -core models.

Performance

Compared to Ivy Bridge Haswell has about 8 % more vector processing power and up to 6 % better single-thread performance. In addition, Haswell consumes about 8% more power under load than a comparable Ivy Bridge model. In addition, an improvement to the sequential CPU performance recorded by 6 % compared to Ivy Bridge ( eight execution ports per core instead of just six). The main optimization was performed with the integrated graphics unit, here's a 20% greater performance than the previous Intel HD 4000 was achieved ( Haswell HD 4600 vs. HD 4000 Ivy Bridge ).

Weaken

Many hardware manufacturers have complained that Haswell processors tend to overheat under full load and be hot at the same clock than previous processors.

This was due to an altered production of Intel, according to which the space between the die and the unhoused processor and the heat spreader is filled with a thermally conductive paste. In the before last generation processor, this area was still soldered.

Due to this small change the overclocking of the processor is considerably more difficult.

Means against overheating

To bring the Haswell processors to much lower temperatures, you can remove the heatspreader, colloquially also " the CPU heads " in the English room for this purpose, the term " delidding "

After that, the heat spreader is free, ground and polished from the Intel thermal paste. Then, a new " liquid metal paste " between the die and the heat spreader as well inserted between the heat spreader and the radiator. By this measure the temperature of the CPU C. decreases by up to 20 °
