Pentium-Processor-M
Pentium III Processor-M. On
July 30, 2001 Intel relased five new Pentium III Processor-Ms at speeds
of 1.13 GHz, 1.06 GHz, 1.0 GHz, 933 MHz, and 866 MHz.
The mobile Pentium III processor-M provides almost a 50 percent performance
gain over the previous mobile Intel® Pentium® III processor
on data intensive applications.
It features several architectural advancements including: 512KB L2 cache
(twice the L2 cache size of the previous generation), the new Data Prefetcher
(an L2 cache enhancement that results in improved performance) and a
133-MHz processor system bus.
In addition, the processor supports Enhanced Intel SpeedStep™
technology that automatically switches between Maximum Performance Mode
and Battery Optimized Mode based on the application demand on the processor,
providing the best balance of performance and low power.
The processor also uses new Intel packaging technology enabling thinner
and lighter mobile PCs. The new Deeper Sleep mode provides a power reduction
from previous low power sleep states to help extend battery life ¾
reaching power levels as low as two tenths of a watt or less ¾
even while running software applications.
Also released was the Intel 830 Chipset.
The Intel® 830 Chipset family includes three new chipsets designed
to take advantage of the mobile Pentium III processor-M performance
and low power characteristics. The Intel 830MP supports external graphics
and is available today. Later this year Intel will provide the Intel
830M with high-performance integrated graphics, while the Intel 830MG
will offer integrated graphics for lower cost systems.
The new chipset uses high-performance PC-133 SDRAM, which is 33 percent
faster than memory supported in the previous Intel 440BX chipset. It
also includes 1GB memory support for a 50 percent increase over previous
generations.
The Intel 830 Chipset also features a hub architecture that increases
bandwidth and provides for a smoother and richer multimedia and Internet
experience. The chipset improves connectivity and flexibility by accommodating
a total of six USB ports, while integrated local area network (LAN)
capability minimizes board space and reduces cost. Like the new mobile
processors, the chipset integrates the new Deeper Sleep low power mode
to further conserve power and help prolong battery life.
Pentium 4 Processor-M.
On March 4, 2002 Intel introduced the 1.6 and 1.7 GHz Pentium 4 processor-M
which is designed on Intel's 0.13-micron process technology.
On April 23, 2002 the 1.80, 1.50 and 1.40 GHz Pentium 4 processor-Ms
were introduce, and on June 25, 2002 the 1.9 and 2 GHz Pentium 4 processor-Ms
were announced. Intel announced the 2.2 GHz Pentium 4 processor-M on
September 16, 2002 and the 2.4 GHz model was released on January 14,
2003.
Using the automatic capability of the Enhanced Intel Speed Step technology,
the mobile Pentium 4 Processor-M 2.4 GHz runs at up to 2.4 GHz at 1.3
volts (Maximum Performance Mode). In Battery Optimized Mode, the processor
runs at 1.2 GHz at 1.2 volts, consuming less than 2 watts of average
power.
High performance is provided by the Intel(R) NetBurst(TM) Micro-Architecture,
consisting of: a 400 MHz processor system bus, Hyper Pipelined Technology,
an Execution Trace Cache, Rapid Execution Engine, and 144 Streaming
SIMD instructions (SSE2). It also includes a 512k on-die L2 cache.
The mobile Intel Pentium 4 processor-M operates at low voltage, allowing
it to consume minimal power. Low power consumption is made possible
using the Intel(R) Enhanced Intel SpeedStep(TM) technology, which automatically
switches between Maximum Performance Mode and Battery Optimized Mode
based on the application demand. A technology called Deeper Sleep Alert
State allows the processor to operate as low as 1 volt, and reach power
levels as low as half a watt -- even while running software applications.
To help lower thermal design power, the mobile Intel Pentium 4 Processor-M
supports an enhanced version of the Intel Mobile Voltage Positioning.
The combination of these power management technologies helps to extend
battery life by making it possible for the processor to consume less
than two watts of average power.
Also released in March 2002 with the Pentium 4 processor-M
was the Intel 845 Chipset.
The Intel(R) 845 Chipset family includes two new chipsets, the 845MP
and 845MZ. Both are designed, validated and optimized for the mobile
Pentium 4 Processor-M. The Intel 845MP supports external graphics and
is available today. The 845MZ will be available later this year.
The Intel 845MP offers external AGP 4X graphics support, a 400MHz processor
system bus, and DDR 266 MHz SDRAM for up to 1GB memory support. The
new chipset also supports Enhanced Intel SpeedStep technology, Deeper
Sleep Alert State, a low-power graphics power management mode and an
internal timer that automatically turns off the chipset clock when the
chipset is inactive.
In January 2003, Intel introduced the Intel 852GM integrated
graphics mobile chipset, which brings advanced levels of performance
and flexibility to PC users.
When combined with either the Mobile Intel Pentium 4 processor
or the mobile Intel® Celeron® Processor, the chipset delivers
the advantages of Double Data-Rate (DDR) 266 / 200 memory capability
and a 400 MHz system bus. The chipset includes six integrated, Hi-Speed
Universal Serial Bus (USB) 2.0 ports, which offer 40 times more bandwidth
than USB 1.1. PCs equipped with Hi-Speed USB 2.0 capabilities allow
users to quickly and easily add peripherals to PCs.
The Intel 852GM chipset supports advanced mobile power management features
that help extend battery life, including Enhanced Intel SpeedStep®
technology, Intel's Deep Sleep and Deeper Sleep.
