The new Intel Core microprocessors fourth generation “Haswell”

Today introduced us its new Intel microprocessors fourth “Haswell” in between them had the opportunity to try the most powerful of them: the Core i7-4770K . To complement the information, we bring you information on all models released today by Intel.


Before reading, we recommend reading our articles describing the architecture and features of Intel Core microprocessors fourth generation “Haswell”:

In short, the new Intel Core microprocessors fourth generation “Haswell” We and GPU architectures offer more refined performance per cycle somewhat higher overclock best features, smarter HyperThreading technology, new, modern instruction sets and architecture most solid graphical, compatible and optimized for GPU accelerated computing (OpenCL API), characteristics superior to those present in the now “old but still effective” third-generation Core “Ivy Bridge”.

Haswell performance

According to leaked earlier reviews and official reviews released today, current applications are not able to exploit the potential of new microprocessor, but still gets results slightly higher than Ivy Bridge.

Future applications optimized for the new AVX 2.0 instruction sets and impelled FMA3 new chip performance by up to 70% , factor which added to its increased performance in actual applications, make this new generation of microprocessors in a better choice than Ivy Bridge .

The socket

Unfortunately all the improvements in Haswell require physical and electrical changes introduced by the new Intel socket LGA 1150 they debut these new microprocessors, which is assumed as it is backwards compatible with the old familiar LGA 1155 socket.

The new LGA 1150 socket unlike previous and ephemeral sockets LGA 1155 (Sandy Bridge and Ivy Bridge) and LGA 1156 (Nehalem) will force a long time (until 2016) .

Haswell-DT: Haswell for desktop

The most powerful and feature-rich variants of Haswell, and oriented desktops equipped with socket LGA 1150 motherboards. Initially be made up of Core i7/i5 4000 series microprocessors, which are detailed below:

Within a few weeks are expected microprocessors Series Core i3-4000, but as recently confirmed Intel, Pentium and Celeron not exist based on Haswell .

Haswell-MB: Haswell for laptops

Haswell variant designed for notebooks equipped with PGA socket 946 motherboards. This variant is very similar to in terms of performance and features, but unlike its desktop brother, is optimized for low power consumption.

Currently Intel has introduced five new microprocessors based on Haswell-MB:

Haswell-H: Haswell for notebooks / ultrabooks high end and All-in-One

The first high-performance SoC Intel, and equipped with 128MB of memory EDRAM by way of a fast cache fourth level (L4), which will increase CPU performance and powerful integrated Pro 5200 “Haswell GT3E” (some variants have this feature disabled).

The Haswell SoC BGA-H 1364 and used contacts are soldered directly to the motherboard.

Intel gives us a total of five models based on Haswell-H:

Other variants of Haswell

Within a few weeks should make its appearance SoC-ULT Haswell, Haswell variant aimed at long-range Ultrabooks. Haswell-ULT conformnado be up to two cores and Iris Graphics 5100, unlike L4 not possess in-die memory, but is equipped with the IGP GT3 (virtually identical to GT3E).


Haswell stands as one of the most complete released by Intel microprocessors long: Feature-rich, ready for future applications with CPU and GPU performance quite competent (over-all in the latter).

Haswell Perhaps not the great improvement that many current owners of previous generation Core chips (1/2 ° / 3 °) expected in terms of performance with existing applications and games, but it certainly is a great choice for users who wish to purchase a new computer and want greater investment protection, performance, scalability and compatibility with future games and applications, with features such as Perceptual Computing and Graphics Headless , who will be attending the games and operating systems next generation.
