Pentium M is an Intel processor targeted to the mobile market and used on the first generations of the Centrino platform. In this tutorial we will present the main features of this processor and tables containing all models released to date.

Centrino isn’t a laptop processor but a platform containing specific components set by Intel: a given processor, a given chipset and a given wireless network. A laptop can only be called Centrino if it has these three components. Please read our Everything you Need to Know About The Centrino Platform for further details about subject.

Pentium M processor was released on March 2003 using Intel’s sixth generation microarchitecture, i.e., the same architecture used by Pentium Pro, Pentium II and Pentium III processors. To learn more about how Pentium M processor works, read our tutorial Inside Pentium M Architecture.

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 tables listing all Pentium M models released to date.

The first Pentium M models were based on a core called Banias, which had a 32 KB L1 instruction cache, a 32 KB L1 data cache, a 1 MB L2 cache, worked externally at 400 MHz (100 MHz transferring four data per clock cycle), had SSE2 instructions support, Enhanced SpeedStep technology on models SL6NA and SL6P4 (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.

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 (click here to learn more about this 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.
