O diretor t\u00e9cnico da AMD afirma que a empresa n\u00e3o expressou qualquer inten\u00e7\u00e3o de implementar suporte para quatro threads por n\u00facleo em futuros processadores. A ideia de SMT4 n\u00e3o \u00e9 t\u00e3o precoce assim \u2014 muito nessa \u00e1rea depende da disponibilidade de software capaz de aproveitar as vantagens do multithreading dessa forma. A IBM, por exemplo, h\u00e1 muito oferece processadores de servidor com suporte para essa quantidade de threads por n\u00facleo.<\/p>\n

\"A<\/p>\n

Em entrevista ao site Tom's Hardware<\/a><\/noindex> o diretor t\u00e9cnico da AMD, Mark Papermaster, respondeu \u00e0 pergunta sobre a possibilidade de implementar suporte a quatro threads por n\u00facleo no segmento desktop e come\u00e7ou seu coment\u00e1rio afirmando a aus\u00eancia de quaisquer compromissos oficiais no momento. Rumores atribu\u00edram \u00e0 AMD a inten\u00e7\u00e3o de implementar suporte a SMT4 em processadores de servidor Milan com arquitetura Zen 3, mas as apresenta\u00e7\u00f5es oficiais publicadas posteriormente desmentiram essa informa\u00e7\u00e3o.<\/p>\n

Mark Papermaster tentou abordar a quest\u00e3o do SMT4 de maneira o mais abstrata poss\u00edvel, enfatizando a relut\u00e2ncia em associar essa ideia aos planos existentes da empresa. Sob essas condi\u00e7\u00f5es, ele avaliou essa fun\u00e7\u00e3o dos processadores de forma bastante objetiva. Segundo ele, no segmento desktop, alguns usu\u00e1rios at\u00e9 desabilitam a multithreading dos n\u00facleos. Alguns aplicativos se beneficiam do uso dessa fun\u00e7\u00e3o, enquanto outros n\u00e3o. A pr\u00f3pria concep\u00e7\u00e3o de processar quatro threads em um n\u00facleo n\u00e3o \u00e9 nova, sendo amplamente aplicada no segmento de servidores. Mark at\u00e9 mencionou a exist\u00eancia de solu\u00e7\u00f5es de hardware que suportam SMT4, insinuando suavemente os processadores IBM Power, que j\u00e1 tinham essa capacidade desde o in\u00edcio desta d\u00e9cada. Essencialmente, como afirma Mark, a justificativa para a implementa\u00e7\u00e3o do SMT4 \u00e9 determinada apenas pela exist\u00eancia de uma massa cr\u00edtica de aplicativos que possam trabalhar com efici\u00eancia nesse setor de mercado espec\u00edfico.<\/p>\n
