Overview
The Pentium M represented a new and radical departure for Intel, as it was not a low-power version of the desktop-oriented Pentium 4, but instead a heavily modified version of the Pentium III Tualatin design (itself based on the Pentium Pro core design). The Pentium 4 brand refers to Intel 's line of single- core mainstream desktop and Laptop Central processing units (CPUs introduced Pentium III variants Katmai The first Pentium III variant was the Katmai (Intel product code 80525 Pentium III variants Katmai The first Pentium III variant was the Katmai (Intel product code 80525 The Pentium Pro is a sixth-generation X86 -based Microprocessor developed and manufactured by Intel introduced in November 1995 It is optimised 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, the Pentium M runs at a lower clock speed than the laptop version of the Pentium 4 (The Pentium 4-Mobile, or P4-M), but with similar performance - a 1. The Pentium 4 brand refers to Intel 's line of single- core mainstream desktop and Laptop Central processing units (CPUs introduced 6 GHz Pentium M can typically attain the performance of a 2. 4 GHz Pentium 4-M. [2] The Pentium M (model 740) has been tested to perform up to about 7,400 MIPS and 3. 9 GFLOPS (using SSE2). [3]
The Pentium M coupled the execution core of the Pentium III with a Pentium 4 compatible bus interface, an improved instruction decoding/issuing front end, improved branch prediction, SSE2 support, and a much larger cache. SSE2, Streaming SIMD Extensions 2, is one of the IA-32 SIMD (Single Instruction Multiple Data Instruction sets SSE2 was first introduced by The usually power-hungry secondary cache uses an access method which switches on only the portion being accessed.
Other power saving methods include dynamically variable clock frequency and core voltage, allowing the Pentium M to throttle clock speed when the system is idle in order to conserve energy, using the SpeedStep 3 technology (which has more sleep stages than previous versions of SpeedStep). SpeedStep is a Trademark for a series of technologies (including SpeedStep SpeedStep II and SpeedStep III built into some Intel With this technology, a 1. 6 GHz Pentium M can effectively throttle to clock speeds of 600 MHz, 800 MHz, 1000 MHz, 1200 MHz, 1400 MHz and 1600 MHz; these intermediate clock states allow the CPU to better throttle clock speed to suit conditions. The power requirements of the Pentium M varies from 5 watts when idle to 27 watts at full load. This is useful to notebook manufacturers as it allows them to include the Pentium M into smaller notebooks.
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. DFI, or Diamond Flower Inc, is a major Motherboard manufacturer based in Taiwan. Micro-Star International (MSI is a Computer hardware Manufacturer most well known for Desktop computer Motherboards A Home Theater PC ( HTPC) or media PC is a convergence device that combines the functions of a Personal computer and a Digital video recorder. An adapter, the CT-479, has also been developed by ASUS to allow the use of Pentium M processors in selected ASUS motherboards designed for Socket 478 Pentium 4 processors. ASUSTeK Computer Incorporated (Asus () ( is a Taiwan -based multinational company that produces Motherboards Graphics cards Optical drives In Computing, Socket 478 is a type of CPU socket used for Intel 's Pentium 4 and Celeron series CPUs. The Pentium 4 brand refers to Intel 's line of single- core mainstream desktop and Laptop Central processing units (CPUs introduced Shuttle Inc. offers packaged Pentium M desktops, marketed for low energy consumption and minimal cooling system noise. Shuttle (TAIEX2405 is a Taiwan -based manufacturer of Motherboards, barebone computers, complete PC systems 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. An embedded system is a special-purpose Computer system designed to perform one or a few dedicated functions often with Real-time computing constraints

Banias
As the M line was originally designed in Israel, the first Pentium M was identified by the codename Banias, named after an ancient site in the Golan Heights. The Pentium M brand refers to only two single-core 32-bit mobile CPUs codenamed the Banias and Dothan, and targeted at the consumer market of For a topic outline on this subject see List of basic Israel topics. For the city in northwestern Syria, see Baniyas. For the processor formerly codenamed Banias see Pentium M. Borders of Israel The Golan Heights ( الجولان al-Jawlān, הגולן ha-Golan) is a strategic Plateau and mountainous Given the product code 80535, it initially had no model number suffix, but was later identified as the Pentium M 705. It was manufactured on a 130 nm process, was released at frequencies from 900MHz to 1. 7 GHz using a 400 MT/s FSB, and had 1 MiB of Level 2 cache. Gigatransfer (GT and Megatransfer (MT are terms used in computer technology referring to a number of data transfers (or operations In Personal computers the Front Side Bus ( FSB) is the bus that carries data between the CPU and the northbridge. A mebibyte (a contraction of me ga bi nary byte) is a unit of Information or Computer storage, abbreviated MiB. The core average TDP (Thermal Design Power) is 24. The Thermal Design Power (TDP (sometimes called Thermal Design Point) represents the maximum amount of power the cooling system in a computer is required to dissipate 5 watts.
The CPUID signature for a Banias is 0x69X. The CPUID Opcode is an instruction (its name derived from CPU IDentification for the X86 architecture
Dothan
Intel launched its improved Pentium M, formerly known as Dothan, named after another ancient town in Israel, on May 10, 2004. Dothan was a city located at north of Shechem, and about 100 km north of Hebron. Events 1291 - Scottish Nobles recognize the authority of Edward I of England. "MMIV" redirects here For the Modest Mouse album see " Baron von Bullshit Rides Again " Dothan Pentium M processors (product code 80536) are among the first Intel processors to be identified using a "processor number" rather than a clockspeed rating, and the mainstream versions are known as Pentium M 710 (1. 4 GHz), 715 (1. 5 GHz), 725 (1. 6 GHz), 735 (1. 7 GHz), 740 (1. 73 GHz), 745 (1. 8 GHz), 750 (1. 86 GHz), 755 (2. 0 GHz), and 765 (2. 1 GHz). The processor supports neither hyperthreading nor SSE3. Hyper-threading (officially termed Hyper-Threading Technology or HTT) is an Intel-proprietary technology SSE3, also known by its Intel code name Prescott New Instructions (PNI, is the third iteration of the SSE instruction set for the IA-32 architecture
These 700 series Pentium M processors retain the same basic design as the original Pentium M, but are manufactured on a 90 nm process, with twice the secondary cache. The 90 nanometer (90 nm process refers to the level of CMOS process technology that was reached in the 2002-2003 timeframe by most leading semiconductor companies Die size, at 84 mm², remains in the same neighborhood as the original Pentium M, even though the 700 series contains approximately 140 million transistors, most of which make up the 2 MiB cache. TDP is also down to 21 watts (from 24. The Thermal Design Power (TDP (sometimes called Thermal Design Point) represents the maximum amount of power the cooling system in a computer is required to dissipate 5 watts in Banias), though power use at lower clockspeeds has increased slightly. However, tests conducted by third party hardware review sites show that Banias and Dothan equipped notebooks have roughly equivalent battery life. Additionally third party hardware review sites have benchmarked the Dothan at approx 10-20% better performance than the Banias in most situations.
The processor line has models running at clock speeds from 1. 0 GHz to 2. 26 GHz as of July 2005. The models with lower frequencies were either low voltage or ultra-low voltage CPUs designed for even better battery life and reduced heat output. The 718 (1. 3 GHz), 738 (1. 4 GHz), and 758 (1. 5 GHz) models are low-voltage (1. 116 V) with a TDP of 10 W, while the 723 (1. 0 GHz), 733 (1. 1 GHz), and 753 (1. 2 GHz) models are ultra-low voltage (0. 940 V) with a TDP of 5 W.
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) (and the PAE support required for it was enabled, unlike earlier Pentium Ms that had it disabled). The NX bit, which stands for No eXecute, is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions (or code 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.
In July 2005, Intel released the 780 (2. 26 GHz) and the low-voltage 778 (1. 60 GHz).
The CPUID signature for a Dothan is 0x6DX. The CPUID Opcode is an instruction (its name derived from CPU IDentification for the X86 architecture
This processor is still commercially offered, for example in the current version 701 of the Asus Eee PC subnotebook. The ASUS Eee PC (pronounced as the letter e, IPA /iː/ is a Subnotebook / Netbook computer designed by ASUS. A subnotebook is a small and lightweight portable Computer, with most of the features of a standard Laptop computer but smaller
Core Solo and Core Duo
The next generation of processors (with a microarchitecture being a derivative of P6 found in Pentium M CPUs), codenamed Yonah, was released under the Intel Core brand, as Core Duo and Core Solo (Duo with one disabled core). The Core brand refers to Intel 's 32-bit mobile Dual-core X86 CPUs that derived from the Pentium M branded processors The P6 Microarchitecture is the sixth generation Intel X86 Microprocessor architecture released in 1995. The Core brand refers to Intel 's 32-bit mobile Dual-core X86 CPUs that derived from the Pentium M branded processors
