Intel has announced its latest generation Core i3,i5 and i7 processor, promising that they will offer “the biggest improvement in battery life in Intel history” compared to previous models. Intel is calling these chips “4th generation”.

The logic behind this is due to the increased number of people using ultrabooks and tablets. Intel believe that we will see larger laptops become thinner and lighter in their design and that there will be a bigger demand for touch PCs. Although these new Haswell CPUs will be included in desktops and all-in-one computers, its benefits will probably be felt more in the thinner and lighter machines.

Battery Life

Intel are claiming that the ultra low voltage 4th generation processors will be twenty times more power efficient when idle (or asleep) than the Sandy Bridge computers that came before them. To make a comparison: the new generation i7-4650U will give up to three hours extra battery life during HD video playback compared to the 2012 Core i7-3667U laptop chip. They also claim that you can leave your laptop in standby for ten days.

The plan to achieve longer battery life doesn’t stop there. Intel are hoping that in the future they can also create power savings when you connect a laptop to an external display. They hope to convince monitor manufacturers to use a technology called Panel Self Refresh ,which will enable the screen to refresh an image itself, without using the graphics processor. The monitor will be able to tell the GPU to shut down and save power.


Intel is also claiming a 2x improvement in the graphics capability of the new chip’s HD 5000 graphics core compared to the previous HD 4000 generation.

Last month Intel also announced two extra levels of graphics for more professional use, called Iris and Iris Pro, numbered HD 5100 and HD 5200.

The combination of a significant battery life increase and faster graphics means the new 4th Generation core processor is well worth looking at. Intel are formally launching it on June 4th, so expect to see most, if not all PC manufacturers jumping on board.
