 For
the first time in over a year, Intel will be introducing
a new family XScale processors to power the next
generation of Pocket PCs, other PDAs and mobile
devices. The
new family, the PXA27x Processors, focus more on
multimedia and wireless data transfer. |

Formerly
codenamed "Bulverde," the new round of
PXA27x processors will range in speed from 312MHz
to 624MHz, and will feature MMX Technology to aid
in increasing the usable speed of the processor
above what the classic megahertz scale suggests. Intel's
Wireless MMX Technology allows for better multimedia
performance over current XScale
chips. Another benefit of MMX is the
fact that it has been around for years, allowing
gaming, video, encryption and even voice recognition
applications to be written more quickly since software
developers are already familiar with MMX instruction
sets.
VGA
displays are coming to several new
Pocket PCs
over the next few months, and the PXA27x XScale will make the
experience not only possible, but hopefully fluid and vibrant. A
multimedia accellorator called the 2700G, which will accompany PXA27x
chips on higher-end Pocket PCs, will also make viewing video and
listening to audio files faster and smoother. If
you have've owned a notebook with an Intel Mobile
Processor, you may be familiar with SpeedStep. SpeedStep
is essentially a technology that allows an Intel
processor to step up or step down the speed at
which a CPU is operating to conserve power when
few demands are placed on it. The PXA27x
family of processors will have Wireless Intel SpeedStep
technology, which, according to Intel, significantly
increases battery life. Some reports, again
by Intel, show that the PXA27x processor can run
up to and beyond 75% longer than current processors
when performing tasks such as video or music playback.
Several
Pocket PCs with the new PXA27x chips, including
the Dell Axim X30 and iPAQ
hx4705, are set to
debut throughout the rest of 2004. |
