So the processor's Turbo Mode is based on revision 2.0, which makes the Turbo mode much more dynamic. It can alter several stages and levels "per core" in clock frequencies. Depending on CPU load, one or more CPU cores will run above its advertised specification. It has changed as there are several steps in which the Turbo mode will be utilized. Dynamic Turbo (Turbo 2.0) will allow the CPU power to exceed the TDP value when the rest of the platform is relatively cool. The frequency gain is expected to be up to 37% for a short time and say 20% in other scenarios. For overclockers it will be interesting to know that each CPU core can be overclocked independently. So if you learn that one CPU core is a little weaker... you could clock it lower and the rest higher, albeit it's a little far-fetched.
But let's bullet up some of the primary features and we'll focus on the 4770K right now:
4-Way Multi-Task Processing: Runs 4 independent processing threads in one physical package.
Intel Turbo Boost Technology 2.0: Dynamically increases the processor frequency up to 3.90 GHz when applications demand more performance. Speed when you need it, energy efficiency when you don't.
Intel Hyper-Threading Technology: Allows each core of the processor to work on two tasks at the same time providing unprecedented processing capability for better multi-tasking, and for threaded applications.
Intel Smart Cache: 6MB of shared cached allows faster access to your data by enabling dynamic and efficient allocation of the cache to match the needs of each core significantly reducing latency to frequently used data and improving performance.
CPU Overclocking Enabled (with Intel Z87 Express Chipset), fully unlocked core multiplier, power, and DDR3 memory ratios enable ultimate flexibility for overclocking.
Graphics Overclocking Enabled (with Intel H87 Express Chipset), unlocked graphics multiplier allows for overclocking to boost the graphics clock speed.
Integrated Memory Controller: Supports 2 channels of DDR3-1600 memory with 2 DIMMs per channel. Support for memory based on the Intel Extreme Memory Profile (Intel XMP 1.3) specification2 up-to 2400 and some even 2800 MHz.
Chipset/Motherboard Compatibility: Compatible with supported Intel 6 Series Chipsets and Series 7 chipsets.
AES-NI: Provides 6 processor instructions that help to improve performance for AES encryption and decryption algorithms.
Built-in Visuals: New enhanced built-in visual features deliver a seamless visual PC experience for doing everything from simple e-mail to enjoying the latest 3D and HD entertainment.
The built-in visuals suite includes:
Intel Quick Sync Video Technology: Media processing for incredibly fast conversion of video files for portable media players or online sharing.
Intel InTru3D: Stereoscopic 3D Blu-ray playback experience in full HD 1080p resolution over HDMI 1.4 with 3D.
Intel Clear Video HD Technology: Visual quality and color fidelity enhancements for spectacular HD playback and immersive web browsing.
Intel Advanced Vector Extensions (Intel AVX2): Increased performance for demanding visual applications like professional video & image editing.
Intel HD Graphics: Significant 3D performance for immersive mainstream gaming on a broad range of titles.
Intel Iris - an integrated GPU
The IGP inside the processor is called the Intel Graphics Media Accelerator HD, and is derived from existing Intel graphics products, but has some nice new improvements. The embedded graphics core is an updated model from all the way back, the Sandy Bridge version, though completely revamped, improved and definitely more powerful with an improved video en/decoder now as well. The Intel 4000 series integrated graphics core is incorporated onto the same die as the CPU, and it also has access to Intel's automatic overclocking Turbo Boost features.
Intel's Haswell desktops will still be branded as "Intel HD Graphics." High-end desktop parts will get the "HD 4600" label, with lower-end parts branded as "HD 4400" and "HD 4200." Compared to 3rd Gen Intel Core processors, when it comes to 3D graphics performance you'll see benefits like 3x 3D performance improvement for desktop R-series processors with Intel Iris Pro graphics. Intel Iris graphics will be faster than Intel ever has released in the past. We do have to state though that Haswell Iris also has far more advanced video & photo editing features. The 4th Generation Intel Core processors will get faster Intel Quick Sync Video technology, MJPEG acceleration and, also interesting, full 4K x 2K UltraHD display resolution support, a three screen collage mode display. The new graphics core has DirectX 11.1, OpenGL 4.1 and OpenCL 1.2 support as well as higher performance compared to the predecessor found in Ivy and Sandy Bridge processors.
Haswell has a very interesting and capable GPU, gaming wise you can expect entry-level dedicated graphics performance but we like to see the unit more as a video processor. Very good for stuff like Blu-ray playback and it supports 3D playback thanks to HDMI 1.4a implementation. It supports Intel Wireless Display (WIDI), will use the embedded DisplayPort standard to connect the GPU to the screen, and is capable of handling the task of transcoding video.
