Pentium M

<table><tbody><tr><td></td></tr></tbody></table>
<p>The Pentium M is a family of mobile 32-bit single-core <a href="/facts/X86/Kypq5fgu">x86</a> <a href="/facts/Microprocessor/Fx9CaQht">microprocessors</a> (with the modified <a href="/facts/Intel/SMF0gJJX">Intel</a> <a href="/facts/P6_(microarchitecture)/e8zEuP4E">P6 microarchitecture</a>) introduced in March 2003 and forming a part of the Intel <a href="/facts/Centrino/CLhRhzU5">Carmel</a> notebook platform under the then new <a href="/facts/Centrino/CLhRhzU5">Centrino</a> brand. The <i>Pentium M</i> processors had a maximum <a href="/facts/Thermal_design_power/Idcy26tM">thermal design power</a> (TDP) of 5–27 W depending on the model, and were intended for use in laptops (thus the "M" suffix standing for <i>mobile</i>). They evolved from the core of the last <a href="/facts/Pentium_III/sV1v2Frq">Pentium III</a>–branded CPU by adding the <a href="/facts/Front-side_bus/LgYSB7Wl">front-side bus</a> (FSB) interface of <a href="/facts/Pentium_4/6tIFuHIF">Pentium 4</a>, an improved instruction decoding and issuing front end, improved <a href="/facts/Branch_predictor/pGPhFMj5">branch prediction</a>, <a href="/facts/SSE2/cheNDPSK">SSE2</a> support, and a much larger cache.
</p><p>The Pentium M replaced the laptop version of the <a href="/facts/Pentium_4/6tIFuHIF">Pentium 4</a> (the <i>Pentium 4-Mobile</i>, or <i>P4-M</i>), which suffered from power consumption and heat problems. The first Pentium M–branded <a href="/facts/CPU/Jxp1bqMV">CPU</a>, code-named Banias, was followed by Dothan. The Pentium M line was removed from the official price lists in July 2009, when the Pentium M-branded processors were succeeded by the <a href="/facts/Intel_Core/lwa8VSdT">Core</a>-branded <a href="/facts/Dual-core/ABNb65hQ">dual-core</a> mobile <a href="/facts/Yonah_(microprocessor)/tGcu7GJu">Yonah</a> CPU with a modified microarchitecture.
