Introduction
Pentium M is an Intel processor targeted to the mobile market and used on Centrino platform. Intel’s Centrino platform is a set of three technologies developed for notebooks:
• Pentium M Processor
• Intel 855 or 915 chipsets
• Intel/PRO Wireless networking
A notebook can only be called Centrino if it has all these three components. A Pentium M-based notebook that doesn’t have Intel/PRO Wireless networking, for example, cannot be called Centrino.
Pentium M processor was released on March 2003 using Intel’s sixth generation microarchitecture, the same architecture used by Pentium Pro, Pentium II and Pentium III processors. Pentium M processors can be found with two different cores: Banias (manufactured using 130 nm process) and Dothan (manufactured using 90 nm process). In this tutorial we will explain everything you need to know about these cores and also will post a complete table listing all Pentium M models released to date.
Banias
The first Pentium M models were based on a core called Banias, which has a 32 KB L1 instruction cache, a 32 KB L1 data cache, a 1 MB L2 cache, works externally at 400 MHz (100 MHz transferring four data per clock cycle), has SSE2 instructions support, Enhanced SpeedStep technology (which reduces the CPU clock in order to save battery life when the computer is idle), 130 nm manufacturing process, socket 478 or 479 pinout and 77 million transistors on a area of 3.26 squared inches (82.79 mm2), using copper on its metal layers.
On the table below we list all Pentium M released using Banias core.

Dothan
Dothan core is manufactured under 90 nm manufacturing process and is used on all Pentium M processors found on the market today. It has a 32 KB L1 instruction cache, a 32 KB L1 data cache, a 2 MB L2 cache, works externally at 400 MHz or 533 MHz (100 MHz or 133 MHz transferring four data per clock cycle), has SSE2 instructions support, Enhanced SpeedStep technology (which reduces the CPU clock in order to save battery life when the computer is idle), execute disable technology socket 478 or 479 pinout and 140 million transistors on a area of 3.45 squared inches (87.66 mm2), using copper on its metal layers.
On the table below we list all Pentium M released using Dothan core to date.
