New Features in the Mobile Pentium III Processor
2.1.1
On-die GTL+ Termination
The termination resistors for the GTL+ system bus are integrated onto the processor die. The
RESET# signal does not have on-die termination and requires an external 56.2

Streaming SIMD Extensions
The mobile Pentium III processor is the first mobile processor to implement Streaming SIMD
(single instruction, multiple data) extensions. Streaming SIMD extensions can enhance floating
point, video, sound, and 3-D application performance.

2.1.3
Intel SpeedStep Technology
Intel SpeedStep technology is a new mobile feature developed by Intel. The mobile Pentium III
processors that are enabled with Intel SpeedStep technology have the ability to switch between
two bus ratios and core speeds without having to reset the processor.

Signal Differences Between the Mobile Pentium II
Processor and the Mobile Pentium
Processor and the Mobile Pentium
III Processor
With the exception of BCLK, PICCLK, and PWRGOOD, the CMOS inputs and Open-drain
outputs have changed from 2.5V tolerant, as on the mobile Pentium II processor to 1.5V tolerant.
