Intel Mobile CPUs Specifications
This page has more details on the CPUs listed in the Mobile
CPU Speed Guide on the previous page. It is recommended that you
read up on the CPUs you are considering for your next notebook. Click

Intel Mobile CPUs
Intel Pentium MMX CPUs - Produced at speeds
of 75 - 300 MHz. You should not buy this CPU in new notebooks as it
one of the slowest Mobile processors available.
Pentium II CPUs - The previous laptop speed
king, they have speeds of 233MHz-300MHz. There is also a "Mobile"
variety that consumes less power (which means your battery will last
longer).
Mobile Celerons - On 25 January,1999
Intel released the 266 MHz and 300 MHz Mobile Celeron CPUs. They contain
128K of L2 cache that runs at half the processor speed, similar to a
desktop Celeron. So how fast is a mobile Celeron? Per Intel, "A
mobile Celeron™ processor running at a clock speed of 300 MHz offers
between 17 - 50% performance improvement over a mobile Pentium®
processor with MMX™ technology running at 266 MHz".
On April 5, 2000 Intel released the 333 MHz Mobile Celeron and on 26
April, Intel released a 266 MHz low-voltage mini-notebook CPU.
Then on May 16, Intel released the 366 MHz Mobile Celeron. It was different
from its predecessors because it was manufactured in the new standardized
Micro PGA format and it had the new Quickstart power management features.
Quickstart lets the system power down faster when the computer is idle,
resulting in longer battery life.
The 400 MHz Mobile Celeron was released on June 14, 1999 and the 433
and 466 MHz Mobile Celerons began shipping on 15 September. This was
followed by the 500 MHz Celeron on January 11, 2000 and the 550 MHz
Celeron was released on the 24 April, 2000.
On June 19, 2000 Intel released the 600 and 650 MHz Mobile Celeron,
and a low-power 500 MHz Mobile Celeron for ultra-portables. Then on
September 26, 2000 Intel announced the 700 MHz Mobile Celeron.
On Jan. 3, 2001 Intel launched the Mobile Celeron processor at 800MHz,
which increases the system bus speed from 66MHz to 100MHz. The company
also introduced the 810E2 chipset, which brings faster disk drive performance,
more USB ports and surround sound audio to value PCs.
On March 19, 2001 Intel announced the 750 MHz Celeron with 100 MHz bus
speed.
Mobile Celeron (0.13 microns) - On April
17, 2002 the mobile 1 GHz Celeron in 0.13 micron form factor and with
133 MHz front bus speed was announced. On June 24, 2002 the 133 MHz
mobile Celeron was announced.
Mobile Celeron (400 MHz bus) - On April
17, 2002 the 1.4 and 1.5 GHz mobile Celerons were announced. These celerons
were also made in the 0.13 micron form factor but they use a 400 MHz
front side bus. On September 16, 2002 Intel released the 1.6, 1.7, and
1.8 GHz Mobile Celerons and on January 3, 2002 the 2.0 GHz Mobile Celeon
was introduced.
