Intel Details Fourth-Gen Integrated Core i7 "Haswell" Graphics
A recently released document sheds some light on Intel’s forthcoming Core i7 processors, which will boast new integrated graphics silicon that promises to double or even triple performance compared to existing models. To be more specific, alongside a new iteration of the “Intel HD Graphics” series, named HD 5000, Intel is introducing the “Iris” and “Iris Pro” tiers to its graphics lineup with Haswell, effectively creating a three-tier system for its upcoming Core i7 offerings. Apple is currently being expected to use products from the newest family of processors when the company refreshes its Mac lineup later this year.
As expected with every new generation of CPUs, there will be an across the board performance boost with the fourth-generation Core i7 chips. However, while previous generational changes brought only slight gains to Intel’s respective Ultrabook, laptop and desktop class lineups, Iris and Iris Pro will enjoy huge gains, in some cases showing three fold improvements.
The options start out with the HD 5000 for 15W TDP (Thermal Design Power) U-series chips, moving to the new Iris graphics with 28W U-series silicon. Iris Pro, which uses embedded DRAM instead of shared system memory, promises to double the speed of the current 47-55W H-series laptop processors. The most interested is a tripling in 3D rendering speeds for 65-84W R-series desktop CPUs. According to Intel’s documentation, Iris Pro is also said to be available on certain M-series laptop and K-series desktop chips.
It should be noted that the 11- and 13-inch MacBook Air currently use two U-series chips, a 17W dual-core Ivy Bridge Core i5 processor in its standard configuration and an optional Core i7 version. Apple uses M-series Core i5 and i7 chips for its MacBook Pro and MacBook Pro with Retina display products.
Intel also detailed the three tiers’ feature sets, which support DirectX 11.1, OpenGL 4 and OpenCL 1.2. Display nodes include “enhanced” 4K and 2K output and a 3-screen collage, which looks to eschew the need for a discrete graphics card for multi-panel setups.
Those of you interested in finding out the full specifications, including those related to non-graphics processing performance will have to wait as they are expected to be revealed one day prior to the Computex Taipei trade show.

Anyone who is serious about their gpu doesn't look to their processor for it . With the exception of ultra books but lets face it people don't buy ultra books for supreme gaming power.. More or less for a very lightweight pc/laptop..
Haswell uses less power then ivy bridge so it's really designed for ultra books ...
Small space = small battery.
Intel is king of processors while most everyone who knows a little about this looks to amd for gpu ' s
