Caselet Intel Aims to Lower PC Power Consumption by 300
Times in 10 Years

he world’s largest chip- maker Intel Corporation on Thursday said it is working on
a host of futuristic technologies that would improve the power efficiency of PCs
T300-fold in the next 10 years, as well as ensure the security of data and user identities.
Speaking on the final day of the Intel Developer Forum (IDF) 2011 here, Intel Chief
Technology Officer Mr Justin Rattner said the company was developing technologies to
take computing to the next level, with better performance and lower power consumption.

Energy efficiency was a key theme of the three-day IDF summit this year and a number of
Intel executives demonstrated the efforts being taken by the company in this regard. The
move assumes significance in light of consumers gravitating toward always-on computing
devices with a greater degree of mobility.
Mr Rattner said that Intel’s multi-core technology, in which more than one processing
engine is built into a single chip, has become the accepted methodology for increasing
performance while keeping power consumption low.

These technologies would enable faster web access, improve PC user security and reduce
the requirement for wireless infrastructure to provide the optimal online experience,
among other benefits, he said.
Mr Rattner demonstrated a new technology for better PC security, wherein users would
be able to see images and other data on social networking sites and other platforms only
if the computer recognises his or her face.
The technology will enable parallel cryptographic and facial recognition services to
improve security on Ultrabooks and traditional notebooks, besides desktop PCs, with the
help of Intel microprocessors, he said.
Intel was also collaborating with China Mobile to replace existing “costly base-station
hardware used on cell towers today with a fully programmable and far more cost-effective,
software-based PC alternative”, he noted.

Mr Rattner revealed that Intel Labs was working on a new ‘Near-Threshold Voltage
Processor’ that has enabled an experimental Pentium-class processor unit to deliver five
times better energy efficiency levels, with the ability to run a processor with a solar cell
the size of postage stamp.
