If you have / had a Mac equipped with Core 2 Duo or earlier processors, you probably suffered from Intel's integrated graphics. Graphic performance was never her forte and everything was very bad before the arrival of the Ivy Bridge line, which has integrated graphics chips HD 4000.
But with the future generation of processors (Haswell), Intel intends to change that once and for all.
It will provide two different integrated graphics: one that accompanies processors for ultrabooks (Iris Graphics 5100) and another for notebooks and desktops that are more robust (Iris Pro Graphics 5200). According to Intel, the performance of the Iris Graphics 5100 is twice the current found in ultrabooks, while for the Iris Pro Graphics 5200, triple! Both have support for OpenCL, DirectX 11.1, OpenGL 4.1, three simultaneous displays and 4K resolution (38402160 pixels). This means that, if Apple wants, the Retina display can spread to all lines of Macs, reaching the MacBook Air, iMac and Thunderbolt Display.
Taking into account Intel's new graphics and plans for 24-hour battery life with these Haswell processors, this future generation of chips and Macs promises!
