No entanto, as coisas podem mudar, pois uma pr\u00f3xima corre\u00e7\u00e3o de seguran\u00e7a pode diminuir o desempenho geral nas CPUs da Intel em at\u00e9 30%.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Segundo os relat\u00f3rios, uma falha de design fundamental nos chips de processadores da Intel for\u00e7ou um redesenho significativo dos kernels do Linux e do Windows. A Microsoft lan\u00e7ar\u00e1 as mudan\u00e7as em uma pr\u00f3xima atualiza\u00e7\u00e3o e, de acordo com os benchmarks iniciais, haver\u00e1 um impacto no desempenho de 5-30%, dependendo da tarefa e do modelo do processador.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">O que \u00e9 realmente interessante aqui \u00e9 que esse bug \/ problema de seguran\u00e7a afeta muitas CPUs da Intel. Na verdade, esse bug est\u00e1 presente em todos os processadores Intel que foram produzidos nos \u00faltimos 10 anos.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Como o portal TheRegister reportou, este problema de seguran\u00e7a permite que os programas de usu\u00e1rio normais discernem, at\u00e9 certo ponto, o conte\u00fado da mem\u00f3ria protegida do kernel.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Al\u00e9m disso, parece que esta solu\u00e7\u00e3o de seguran\u00e7a afetar\u00e1 apenas as CPUs da Intel. A AMD afirmou que suas CPUs n\u00e3o est\u00e3o sujeitas a esses tipos de ataques.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">A Microsoft emitir\u00e1 esta corre\u00e7\u00e3o de seguran\u00e7a na pr\u00f3xima semana, por isso, teremos de comparar alguns jogos para ver o quanto essa solu\u00e7\u00e3o afetar\u00e1 o desempenho em CPU da Intel.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">[ATUALIZA\u00c7\u00c3O]<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Felizmente, esta corre\u00e7\u00e3o parece que n\u00e3o afetar\u00e1 o desempenho para aqueles que usam o computador para jogos.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Este bug rec\u00e9m-descoberto \u00e9 mais prov\u00e1vel um perigo para sistemas que executam v\u00e1rias m\u00e1quinas virtuais (VMs).

No entanto, as coisas podem mudar, pois uma pr\u00f3xima corre\u00e7\u00e3o de seguran\u00e7a pode diminuir o desempenho geral nas CPUs da Intel em at\u00e9 30%. Segundo os relat\u00f3rios, uma falha de design fundamental nos chips de processadores da Intel for\u00e7ou um redesenho significativo dos kernels do Linux e do Windows. A Microsoft lan\u00e7ar\u00e1 as mudan\u00e7as em uma pr\u00f3xima atualiza\u00e7\u00e3o e, de acordo com os benchmarks iniciais, haver\u00e1 um impacto no desempenho de 5-30%, dependendo da tarefa e do modelo do processador. O que \u00e9 realmente interessante aqui \u00e9 que esse bug \/ problema de seguran\u00e7a afeta muitas CPUs da Intel. Na verdade, esse bug est\u00e1 presente em todos os processadores Intel que foram produzidos nos \u00faltimos 10 anos. Como o portal TheRegister reportou, este problema de seguran\u00e7a permite que os programas de usu\u00e1rio normais discernem, at\u00e9 certo ponto, o conte\u00fado da mem\u00f3ria protegida do kernel. Al\u00e9m disso, parece que esta solu\u00e7\u00e3o de seguran\u00e7a afetar\u00e1 apenas as CPUs da Intel. A AMD afirmou que suas CPUs n\u00e3o est\u00e3o sujeitas a esses tipos de ataques. A Microsoft emitir\u00e1 esta corre\u00e7\u00e3o de seguran\u00e7a na pr\u00f3xima semana, por isso, teremos de comparar alguns jogos para ver o quanto essa solu\u00e7\u00e3o afetar\u00e1 o desempenho em CPU da Intel. [ATUALIZA\u00c7\u00c3O] Felizmente, esta corre\u00e7\u00e3o parece que n\u00e3o afetar\u00e1 o desempenho para aqueles que usam o computador para jogos. Este bug rec\u00e9m-descoberto \u00e9 mais prov\u00e1vel um perigo para sistemas que executam v\u00e1rias m\u00e1quinas virtuais (VMs). Um grande problema de dados, em escala de servidor, principalmente. Embora esta falha de seguran\u00e7a seja um problema em si, o patch que foi infiltrado no kernel do Linux nas \u00faltimas semanas est\u00e1 causando grandes dores de cabe\u00e7a para a Intel, j\u00e1 que pode retardar o desempenho da CPU em um ambiente de servidor.<\/p>\n<br\/><div class='heateorSssClear'><\/div><div  class='heateor_sss_sharing_container heateor_sss_horizontal_sharing'

diminuir o desempenho em CPUs da Intel em at\u00e9 30% - TVM - Televis\u00e3o de Mo\u00e7ambique\" \/>\n<meta property=\"og:description\" content=\"Atualmente sabemos que as CPUs da Intel executam muito bem todos os jogos modernos. No entanto, as coisas podem mudar, pois uma pr\u00f3xima corre\u00e7\u00e3o de seguran\u00e7a pode diminuir o desempenho geral nas CPUs da Intel em at\u00e9 30%. Segundo os relat\u00f3rios, uma falha de design fundamental nos chips de processadores da Intel for\u00e7ou um redesenho significativo dos kernels do Linux e do Windows. A Microsoft lan\u00e7ar\u00e1 as mudan\u00e7as em uma pr\u00f3xima atualiza\u00e7\u00e3o e, de acordo com os benchmarks iniciais, haver\u00e1 um impacto no desempenho de 5-30%, dependendo da tarefa e do modelo do processador. O que \u00e9 realmente interessante aqui \u00e9 que esse bug \/ problema de seguran\u00e7a afeta muitas CPUs da Intel. Na verdade, esse bug est\u00e1 presente em todos os processadores Intel que foram produzidos nos \u00faltimos 10 anos. Como o portal TheRegister reportou, este problema de seguran\u00e7a permite que os programas de usu\u00e1rio normais discernem, at\u00e9 certo ponto, o conte\u00fado da mem\u00f3ria protegida do kernel. Al\u00e9m disso, parece que esta solu\u00e7\u00e3o de seguran\u00e7a afetar\u00e1 apenas as CPUs da Intel. A AMD afirmou que suas CPUs n\u00e3o est\u00e3o sujeitas a esses tipos de ataques. A Microsoft emitir\u00e1 esta corre\u00e7\u00e3o de seguran\u00e7a na pr\u00f3xima semana, por isso, teremos de comparar alguns jogos para ver o quanto essa solu\u00e7\u00e3o afetar\u00e1 o desempenho em CPU da Intel. [ATUALIZA\u00c7\u00c3O] Felizmente, esta corre\u00e7\u00e3o parece que n\u00e3o afetar\u00e1 o desempenho para aqueles que usam o computador para jogos. Este bug rec\u00e9m-descoberto \u00e9 mais prov\u00e1vel um perigo para sistemas que executam v\u00e1rias m\u00e1quinas virtuais (VMs). Um grande problema de dados, em escala de servidor, principalmente. Embora esta falha de seguran\u00e7a seja um problema em si, o patch que foi infiltrado no kernel do Linux nas \u00faltimas semanas est\u00e1 causando grandes dores de cabe\u00e7a para a Intel, j\u00e1 que pode retardar o desempenho da CPU em um ambiente de servidor.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.tvm.co.mz\/novosite\/2018\/02\/10\/a-proxima-correcao-de-seguranca-pode-diminuir-o-desempenho-em-cpus-da-intel-em-ate-30\/\" \/>\n<meta property=\"og:site_name\" content=\"TVM -

No entanto, as coisas podem mudar, pois uma pr\u00f3xima corre\u00e7\u00e3o de seguran\u00e7a pode diminuir o desempenho geral nas CPUs da Intel em at\u00e9 30%. Segundo os relat\u00f3rios, uma falha de design fundamental nos chips de processadores da Intel for\u00e7ou um redesenho significativo dos kernels do Linux e do Windows. A Microsoft lan\u00e7ar\u00e1 as mudan\u00e7as em uma pr\u00f3xima atualiza\u00e7\u00e3o e, de acordo com os benchmarks iniciais, haver\u00e1 um impacto no desempenho de 5-30%, dependendo da tarefa e do modelo do processador. O que \u00e9 realmente interessante aqui \u00e9 que esse bug \/ problema de seguran\u00e7a afeta muitas CPUs da Intel. Na verdade, esse bug est\u00e1 presente em todos os processadores Intel que foram produzidos nos \u00faltimos 10 anos. Como o portal TheRegister reportou, este problema de seguran\u00e7a permite que os programas de usu\u00e1rio normais discernem, at\u00e9 certo ponto, o conte\u00fado da mem\u00f3ria protegida do kernel. Al\u00e9m disso, parece que esta solu\u00e7\u00e3o de seguran\u00e7a afetar\u00e1 apenas as CPUs da Intel. A AMD afirmou que suas CPUs n\u00e3o est\u00e3o sujeitas a esses tipos de ataques. A Microsoft emitir\u00e1 esta corre\u00e7\u00e3o de seguran\u00e7a na pr\u00f3xima semana, por isso, teremos de comparar alguns jogos para ver o quanto essa solu\u00e7\u00e3o afetar\u00e1 o desempenho em CPU da Intel. [ATUALIZA\u00c7\u00c3O] Felizmente, esta corre\u00e7\u00e3o parece que n\u00e3o afetar\u00e1 o desempenho para aqueles que usam o computador para jogos. Este bug rec\u00e9m-descoberto \u00e9 mais prov\u00e1vel um perigo para sistemas que executam v\u00e1rias m\u00e1quinas virtuais (VMs). Um grande problema de dados, em escala de servidor, principalmente. Embora esta falha de seguran\u00e7a seja um problema em si, o patch que foi infiltrado no kernel do Linux nas \u00faltimas semanas est\u00e1 causando grandes dores de cabe\u00e7a para a Intel, j\u00e1 que pode retardar o desempenho da CPU em um ambiente de servidor.","og_url":"https:\/\/www.tvm.co.mz\/novosite\/2018\/02\/10\/a-proxima-correcao-de-seguranca-pode-diminuir-o-desempenho-em-cpus-da-intel-em-ate-30\/","og_site_name":"TVM -
