Haswell not only promises to be a power-efficnet CPU, but will have system-wide power savings too. And without compromising performance.

Intel CEO Paul Otellini revealed that ‘We’ve already completed the design of Intel’s next generation microprocessor, Haswell,’ and made the claim that laptop charging will become a weekly or even fortnightly affair with Haswell technology.

‘Haswell was designed to enable a 30 per cent reduction in connected standby power over the currently shipping notebooks using our second-generation Intel Core microprocessors [Sandy Bridge], said Otellini, ‘But we can do more than that, we can do much better than that.’

The plan is that not only will the CPU consume much less power than current CPUs, but that the system around it will also be heavily optimised for extending battery life.

‘We’re architecting a system-level power management framework that’s supported by efficient system design throughout the ecosystem that has the opportunity to reduce the platform power by a factor of more than 20 times over our current designs. ‘This means that we’ll be able to enable all-day usage and more than a ten-days, always-connected standby capability on a single charge.’

That should mean that in typical use – a bit of work and a bit of web-browsing, and sleeping the laptop in between use – will result in only having to hunt out the power brick every week or two. It’s brilliant to get a month of use from one Kindle charge, but imagine only have to charge an entire laptop only one a week.

Even more impressively, Otellini said that ‘we’ll do and deliver all this without compromising any of the performance you’ve come to expect from today’s mainstream notebooks. The implications for the ultrabook are huge.’ A fast laptop with a week or two of battery life? What’s not to like.

We expect the Haswell CPU design to arrive in 2013 and to feature heavily in super-thin ultrabooks (presuming Intel’s latest laptop craze lasts that long). Intel’s new chips could give future MacBooks 24 hours of battery life (just like current ARM chips) Today at the Intel’s Developer Forum, Intel unveiled a new processor that will be able to power a x86 computer for 24 hours/10 days of stand-by time off a single charge.

Intel’s new Haswell chip uses a 22-nanometer 3D-transistor architecture that uses 20 times less power than current Sandy Bridge models which are featured in the newest line of Macs. The new chip was demonstrated using solar-power to grab light from a source as small as a light bulb to power the system.  Oh, and the Haswell chips will be faster than current processors.

The new chips will land in 2013, after Intel’s Ivy Bridge in 2012. Recently, Intel revealed that Apple wasn’t entirely pleased with upcoming Intel Chips power usage and were currently investigating other alternatives.  Clearly, Apple’s own ARM AX line which already can provide 24 hour battery life (with PC-sized batteries) is being considered.
