ARM announces Cortex-A7 CPU as its most energy efficient processor

Established maker of mobile CPUs ARM has unveiled the Cortex-A7 MPCore processor, which is said to both improve on performance and offer a longer battery life for mobile phones.

ARM’s Cortex-A7 MPCore CPU is the company’s most energy efficient application processor to date, with a redefined power and performance relationship with big.LITTLE processing.

The Cortex-A7 processor builds on from the low-power Cortex-A8, which is driving many of todays’ smartphones such as the Sony Ericsson Satio.

ARM’s single Cortex-A7 processor is set to deliver five times the energy-efficiency, along with being one fifth the size of the Cortex-A8 processor and all whilst providing greater performance.

Big.LITTLE processing enables high performance and an extended battery life, by pairing the best of the high-performance Cortex-A15 MPCore and ultra-efficient Cortex-A7 processors.

This merging of the two allows devices to seamlessly select the right processor for the right task, based on performance requirements for phones from the likes of LG and Samsung – to name just two.

ARM's Cortex-A7 processor will be aimed at the sub-$100 entry level smartphones, where they could very well be used in developing markets.
