10 points to know about Pentium M processor

  • Introduced in March 2003. This is a modified version of Pentium III Tualatin design.
  • The processor was originally designed for use with laptop Personal computer, thus the "M" stands for mobile.
  • The first Pentium M was identified by the codename Banias, it initially had no model number suffix, but was later identified as the Pentium M 705. This was released at frequencies from 1.3 GHz to 1.7 GHz.
  • Later Intel launched its improved 80536 Pentium M, formerly known as Dothan on May 10, 2004.
  • Revisions of the Dothan core were released in the first quarter of 2005 with the Sonoma chipsets and supported a 533 MT/s FSB and XD (Intel's name for the NX bit). These processors include the 730 (1.6 GHz), 740 (1.73 GHz), 750 (1.86 GHz), 760 (2.0 GHz) and 770 (2.13 GHz). These models all have a TDP of 27 W and a 2 MiB L2 cache.
  • It is optimized for power efficiency, a vital characteristic for extending notebook computer battery life. Running with very low average power consumption and much lower heat output than desktop processors.
  • If we compare with Pentium 4, 1.6 GHz Pentium M can typically attain the performance of a 2.4 GHz Pentium 4-M (laptop version of the Pentium4).
  • Another major area of the architecture change was done to lower the amount of voltage the processor needs to run. The current batch of Pentium M processors uses only 1.5 volts of power to run. Future Low and Ultra-Low versions will only require 1.18 and 1.1 volts respectively.
  • Although Intel has marketed the Pentium M exclusively as a mobile product, motherboard manufacturers such as AOpen, DFI and MSI have been shipping Pentium M compatible boards designed for enthusiast, HTPC, workstation and server applications.
  • Pentium M processors are also of interest to embedded systems manufacturers because the low power consumption of the Pentium M allows the design of fanless and miniaturized embedded PCs.
