For overclocking enthusiasts, Intel's 4th gen CPU has improved memory overclocking support, with up to and beyond 3000MHz possible with the very best memory kits. Memory bandwidth is critically important to Haswell compared to previous generations. High frequency memory performance significantly improves encoding, gaming and benchmarking tasks. The biggest leap in Intel's Haswell processor is the onboard graphics which is now up to 2.6x faster than previous HD4000 found in the Ivybridge CPU. Features Intel® Turbo Boost Technology 2.0
Dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom when operating below specified limits.
Intel® Hyper-Threading Technology
Intel Core i7 delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.
Built-In Visuals - Intel® HD Graphics
Enhanced 3-D1 performance for immersive mainstream and casual gaming. Can support up to three UltraHD* (4K) displays and collage display.
Intel® Wireless Display
Wirelessly stream HD / 3-D video and games to your TV or projector for presentations and entertainment.
Intel® Quick Sync Video
Delivers fast conversion of video for portable media players, online sharing, and video editing and authoring.
Intel® Clear Video HD
Visual quality and color fidelity enhancements for HD playback and immersive Web browsing.
Intel® InTru™ 3D
Stereoscopic 3-D Blu-ray* playback in full 1080p resolution over HDMI* 1.4 and premium audio.
Intel® Advanced Vector Extensions
A set of new instructions to improve software performance for floating point-intensive applications such as audio processing, audio codecs, and image and video editing applications.
Integrated Memory Controller
An integrated memory controller offers stunning memory read/write performance through efficient prefetching algorithms, lower latency, and higher memory bandwidth.
Intel® Smart Cache
The shared cache is dynamically allocated to each processor core, based on workload. This significantly reduces latency, improving performance.
Intel® Virtualization Technology4
Allows one hardware platform to function as multiple “virtual” platforms. Offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.
Advanced Encryption Standard New Instructions
New AES instructions add hardware acceleration to AES algorithms and speeds up the execution of AES applications.
Thermal Solution for Boxed Processors
Includes a four-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance.

Date Issued: 9th May 2014
Intel launched a bevy of Haswell Core processors last June. Presented in a LGA1150 form factor and therefore physically different to the LGA1155 Ivy Bridge processors of the year before, new chipsets were also launched to support these new chips.
Date Issued: 31st Aug 2013
Intel launched premium Haswell chips first, promising mainstream parts in the near future.That near future is now, September 1, as the chip giant is rolling out a comprehensive number of new chips in one fell swoop.
Date Issued: 1st Jun 2013
With PC and mobile converging quicker than ever before, Intel needs to reassert its presence in portable devices with an architecture that can scale across multiple platforms. That quest begins with the introduction of the fourth-generation Core processor family, codenamed Haswell.
