Recibía el nombre por situarse en la parte superior de las placas base con <a href="/wiki/Formato_ATX" class="mw-redirect" title="Formato ATX">formato ATX</a> y por tanto no es un término utilizado antes de la aparición de este formato para computadoras de escritorio. También es conocido como <b>MCH</b> (concentrador controlador de memoria) en sistemas Intel y <b>GMCH</b> si incluye el controlador del sistema gráfico. </p><p>Es el chip que controla las funciones de acceso desde y hasta <a href="/wiki/Microprocesador" title="Microprocesador">microprocesador</a>, <a href="/wiki/AGP" class="mw-redirect" title="AGP">AGP</a> o <a href="/wiki/PCI-Express" class="mw-redirect" title="PCI-Express">PCI-Express</a>, <a href="/wiki/Memoria_de_ordenador" class="mw-redirect" title="Memoria de ordenador">memoria</a> <a href="/wiki/Memoria_RAM" class="mw-redirect" title="Memoria RAM">RAM</a>, vídeo integrado (dependiendo de la placa) y <a href="/wiki/Puente_sur" title="Puente sur">Southbridge</a>. Su función principal es la de controlar el funcionamiento del bus del procesador, la memoria y el puerto <a href="/wiki/AGP" class="mw-redirect" title="AGP">AGP</a> o <a href="/wiki/PCI-Express" class="mw-redirect" title="PCI-Express">PCI-Express</a>. De esa forma, sirve de conexión (de ahí su denominación de "puente") entre la placa madre y los principales componentes del PC: microprocesador, memoria RAM y <a href="/wiki/Tarjeta_de_v%C3%ADdeo" class="mw-redirect" title="Tarjeta de vídeo">tarjeta de vídeo</a> <a href="/wiki/AGP" class="mw-redirect" title="AGP">AGP</a> O <a href="/wiki/PCI_Express" title="PCI Express">PCI Express</a>. Generalmente, las grandes innovaciones tecnológicas, como el soporte de memoria <a href="/wiki/DDR_SDRAM" title="DDR SDRAM">DDR</a> o nuevos <a href="/wiki/Bus_de_datos" class="mw-redirect" title="Bus de datos">FSB</a>, se implementan en este chip. Es decir, el soporte que tenga una placa madre para determinado tipo de microprocesadores, memorias RAM o placas AGP estará limitado por las capacidades del Northbridge de que disponga </p><p>La tecnología de fabricación de un Northbridge es muy avanzada, y su complejidad, comparable a la de un microprocesador moderno. Por ejemplo, en un Chipset, el Northbridge debe encargarse de soportar el bus frontal de alta velocidad que lo conecta con el procesador. Si pensamos en el bus de 400 <a href="/wiki/Megahercio" title="Megahercio">MHz</a> utilizado por ejemplo en el último Athlon XP, y el de 800 <a href="/wiki/Megahercio" title="Megahercio">MHz</a> del Intel Prescott, nos damos cuenta de que es una tarea bastante exigente. Además en algunas placas tienen un adaptador de vídeo integrado lo que le añade trabajo al sistema. Debido a esto, la mayoría de los fabricantes de placas madres colocan un <a href="/wiki/Disipador" title="Disipador">disipador</a> (a veces con un ventilador) encima del Northbridge para mantenerlo bien refrigerado. </p><p>Antiguamente, el Northbridge estaba compuesto por tres controladores principales: memoria RAM, <a href="/wiki/Puerto_(computaci%C3%B3n)" class="mw-redirect" title="Puerto (computación)">puerto</a> <a href="/wiki/AGP" class="mw-redirect" title="AGP">AGP</a> o <a href="/wiki/PCI_Express" title="PCI Express">PCI Express</a> y <a href="/wiki/Bus_(Inform%C3%A1tica)" class="mw-redirect" title="Bus (Informática)">bus</a> <a href="/wiki/Peripheral_Component_Interconnect" title="Peripheral Component Interconnect">PCI</a>. Hoy en día, el controlador PCI se inserta directamente en el <a href="/wiki/Southbridge" class="mw-redirect" title="Southbridge">Southbridge</a> ("<a href="/wiki/Puente_sur" title="Puente sur">puente sur</a>"), y en algunas arquitecturas más nuevas el controlador de memoria se encuentra integrado en el procesador; este es el caso de los Athlon 64 o los Intel i7. </p><p>Los puentes norte tienen un bus de datos de 64 bit en la arquitectura <a href="/wiki/X86" title="X86">X86</a> y funcionan en frecuencias que van desde los 66 MHz de las primeras placas que lo integraban en 1998 hasta 5 GHz de los modelos actuales de SiS para procesadores <a href="/wiki/AMD64" class="mw-redirect" title="AMD64">AMD64</a> </p> <div class="mw-heading mw-heading2"><h2 id="Véase_también"><span id="V.C3.A9ase_tambi.C3.A9n"></span>Véase también</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Puente_norte&action=edit&section=1" title="Editar sección: Véase también"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Puente_sur" title="Puente sur">Puente sur</a></li> <li><a href="/wiki/Chipset" title="Chipset">Chipset</a></li> <li><a href="/wiki/Placa_base" title="Placa base">Placa base</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Enlaces_externos">Enlaces externos</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Puente_norte&action=edit&section=2" title="Editar sección: Enlaces externos"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a rel="nofollow" class="external text" href="http://www.intel.com/design/chipsets/linecard.htm">Intel Chipsets</a> intel.com (en inglés).</li> <li><a rel="nofollow" class="external text" href="http://www.via.com.tw/en/products/chipsets/">Via Chipsets</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20150817170102/http://www.via.com.tw/en/products/chipsets/">Archivado</a> el 17 de agosto de 2015 en <a href="/wiki/Wayback_Machine" title="Wayback Machine">Wayback Machine</a>. via.com.tw (en inglés).</li></ul> <style data-mw-deduplicate="TemplateStyles:r161257576">.mw-parser-output .mw-authority-control{margin-top:1.5em}.mw-parser-output .mw-authority-control .navbox table{margin:0}.mw-parser-output .mw-authority-control .navbox hr:last-child{display:none}.mw-parser-output .mw-authority-control .navbox+.mw-mf-linked-projects{display:none}.mw-parser-output .mw-authority-control .mw-mf-linked-projects{display:flex;padding:0.5em;border:1px solid var(--border-color-base,#a2a9b1);background-color:var(--background-color-neutral,#eaecf0);color:var(--color-base,#202122)}.mw-parser-output .mw-authority-control .mw-mf-linked-projects ul li{margin-bottom:0}.mw-parser-output .mw-authority-control .navbox{border:1px solid var(--border-color-base,#a2a9b1);background-color:var(--background-color-neutral-subtle,#f8f9fa)}.mw-parser-output .mw-authority-control .navbox-list{border-color:#f8f9fa}.mw-parser-output .mw-authority-control .navbox th{background-color:#eeeeff}html.skin-theme-clientpref-night .mw-parser-output .mw-authority-control .mw-mf-linked-projects{border:1px solid var(--border-color-base,#72777d);background-color:var(--background-color-neutral,#27292d);color:var(--color-base,#eaecf0)}html.skin-theme-clientpref-night .mw-parser-output .mw-authority-control .navbox{border:1px solid var(--border-color-base,#72777d)!important;background-color:var(--background-color-neutral-subtle,#202122)!important}html.skin-theme-clientpref-night .mw-parser-output .mw-authority-control .navbox-list{border-color:#202122!important}html.skin-theme-clientpref-night .mw-parser-output .mw-authority-control .navbox th{background-color:#27292d!important}@media(prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .mw-authority-control .mw-mf-linked-projects{border:1px solid var(--border-color-base,#72777d)!important;background-color:var(--background-color-neutral,#27292d)!important;color:var(--color-base,#eaecf0)!important}html.skin-theme-clientpref-os .mw-parser-output .mw-authority-control .navbox{border:1px solid var(--border-color-base,#72777d)!important;background-color:var(--background-color-neutral-subtle,#202122)!important}html.skin-theme-clientpref-os .mw-parser-output .mw-authority-control .navbox-list{border-color:#202122!important}html.skin-theme-clientpref-os .mw-parser-output .mw-authority-control .navbox th{background-color:#27292d!important}}</style><div class="mw-authority-control"><div role="navigation" class="navbox" aria-label="Navbox" style="width: inherit;padding:3px"><table class="hlist navbox-inner" style="border-spacing:0;background:transparent;color:inherit"><tbody><tr><th scope="row" class="navbox-group" style="width: 12%;
