<title>O que &#233; processador: n&#250;cleos, threads, clock, cache e TDP</title>
<description><![CDATA[<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;open sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; white-space: normal; background-color: rgb(254, 255, 255);">
	Tudo o que o seu computador ou celular &eacute; capaz de realizar depende de uma combina&ccedil;&atilde;o de componentes. O mais importante deles &eacute; o<span>&nbsp;</span><strong style="font-weight: 700;">processador (CPU)</strong>, um tipo de chip (circuito integrado) que executa tarefas de acordo com um conjunto espec&iacute;fico de instru&ccedil;&otilde;es. &Eacute; por isso que o processador costuma ser chamado de &ldquo;c&eacute;rebro&rdquo; dessas m&aacute;quinas.</p>
<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;open sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; white-space: normal; background-color: rgb(254, 255, 255);">
	Apesar de n&atilde;o haver um n&uacute;mero grande de organiza&ccedil;&otilde;es que desenvolvem ou fabricam esse tipo de chip &mdash; os maiores nomes incluem Intel, AMD e IBM, com companhias como Qualcomm e Samsung se destacando no segmento m&oacute;vel &mdash;, existe uma grande variedade de processadores, para os mais variados fins.</p>
<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;open sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; white-space: normal; background-color: rgb(254, 255, 255);">
	A despeito disso, os processadores compartilham algumas caracter&iacute;sticas b&aacute;sicas. Voc&ecirc; conhecer&aacute; cinco delas nas pr&oacute;ximas linhas:<span>&nbsp;</span><strong style="font-weight: 700;">n&uacute;cleos</strong>,<span>&nbsp;</span><strong style="font-weight: 700;">threads</strong>,<span>&nbsp;</span><strong style="font-weight: 700;">clock (frequ&ecirc;ncia)</strong>,<span>&nbsp;</span><strong style="font-weight: 700;">mem&oacute;ria cache</strong><span>&nbsp;</span>e<span>&nbsp;</span><strong style="font-weight: 700;">TDP</strong>.</p>
<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;open sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; white-space: normal; background-color: rgb(254, 255, 255);">
	Antes, saiba que, neste texto, o termo &ldquo;computador&rdquo; se refere a todo tipo de dispositivo que pode ser equipado com um processador. Entre eles est&atilde;o desktops, notebooks, servidores, celulares, tablets e smartwatches.</p>
<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;open sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; white-space: normal; background-color: rgb(254, 255, 255);">

<title>Miniaturiza&#231;&#227;o: o que s&#227;o os nan&#244;metros (nm) dos processadores</title>

	Ao comprar um notebook, um celular ou escolher um<span>&nbsp;</span><strong style="font-weight: bold;">processador (CPU)</strong><span>&nbsp;</span>para o seu PC, voc&ecirc; pode se deparar com termos como &quot;10 nan&ocirc;metros&quot; e &quot;5 nm&quot;. Eles expressam o n&iacute;vel de<span>&nbsp;</span><strong style="font-weight: bold;">litografia do chip</strong>, no sentido de indicar a dist&acirc;ncia entre os transistores que o comp&otilde;em.</p>
<p style="margin: 10px 0px 20px; color: rgb(0, 0, 0); font-family: &quot;Open Sans&quot;,sans-serif; font-size: 16px; font-style: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; background-color: rgb(254, 255, 255);">
	Essa medida &eacute; informada porque determina o patamar de sofistica&ccedil;&atilde;o da CPU. Em linhas gerais, quanto menor o n&uacute;mero de nan&ocirc;metros do chip, melhor. Voc&ecirc; vai entender os motivos nos <a href="https://www.infowester.com/nanometros-processadores.php">pr&oacute;ximos par&aacute;grafos</a>.</p>
