Intel adds reduced-power CPUs to its fourth generation roadmap

New Haswell CPUs to run cooler and allow for thinner and lighter laptop and tablet designs

Intel has today announced a new addition to the roadmap of its fourth generation processor line-up, which will be introduced around mid-2013. A line of 10W CPUs has been added to the mix, with Intel suggesting it has been able to do so because the program for its new CPUs is on track and things are going better than expected with the new design.

The 10W TDP (thermal design power) range of CPUs is in addition to the 15W TDP rating that was previously known about the next generation of processors for Ultrabooks. The new line up of lower power CPUs will allow manufacturers to implement Ultrabooks and hybrid tablet devices with thinner and lighter form factors, as well as allow those thinner devices to run much cooler.

It's a CPU that may be able to close the gap between Intel's entry-level CPUs and its mainstream ultra-low voltage products in terms of power consumption. Many current-generation Ultrabooks run a third generation Core i5 CPU with a power rating of 17W, while some thin Windows-based tablets run Atom CPUs that have a power rating of 2W.

Intel's Atom CPUs traditionally have not been able to provide a fast level of performance in tablet devices. It's hoped that these new fourth generation 10W CPUs will bring more speed to thinner and smaller devices in addition to curbing power usage and heat output.

The fourth generation CPUs are codenamed Haswell and Intel will be releasing more information about the new low-power parts at next week's Intel Developer Forum, which is to be held in San Francisco.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
