Mobile Pentium microprocessors had the same features as desktop
Pentiums with the following exceptions:
- Core voltage on mobile Pentiums was lower than on desktop Pentium
microprocessors, usually 2.9 Volt or 3.1 Volt. This directly
translated into lower power consumption.
- Mobile CPUs didn't support dual-processing and processor upgrade
features.
- Local Advanced Programmable Interrupt Controller was eliminated from
the mobile Pentium CPUs.
Mobile processors were manufactured in two packages:
- Ceramic PGA package. These processors had the same part numbers as
desktop Pentium processors, but could be easily identified as mobile
processors from other markings on the chip. Specifically, some
processors had core voltage (2.9V or 3.1V) marked on the top of
the chip, while other processors had "IMPP" engraved on the back
of the CPU. It is also possible to use S-Spec number (usually printed
right after the part number) to identify mobile processors.
- Tape Carrier Package. Microprocessors in this package had much
smaller size and very low profile, but this package could not be used
by end-users because it required additional processing (lead forming
and reflowing onto the PCB).
