Considere as afirmações sobre processadores com o recurso tecnológico.

I. Turbo Boost são mais indicados para equipar computadores de um datacenter.

II. AES New Instructions (AES-NI) são mais indicados para executar aplicações que demandam sigilo.

III. Advanced Smart Cache maximiza a latência na busca de dados na memória cache L2.

  • I. CERTO: There are a few different BIOS features that affect the speed of a server’s CPU cores. One such feature is Turbo Boost, which is found on some Intel Xeon servers. Turbo Boost works similar to overclocking, in that it allows CPU cores to run faster than their base frequency.Turbo Boost, which is sometimes disabled by default, tends to be a safe feature to use because it will only increase CPU core frequency if the CPU is consuming less than its rated power and is operating below its rated temperature.The actual amount of additional processing power that Turbo Boost will yield depends on the number of CPU cores that are active, but often provides two to three frequency steps. In any case, all of the active cores within the CPU will run at the same frequency.

    II. CERTO: Intel® AES-NI is a new encryption instruction set that improves on the Advanced Encryption Standard (AES) algorithm and accelerates the encryption of data in the Intel® Xeon® processor family and theIntel® Core™ processor family.

    III. ERRADO: It basically means is that the L2 cache inside a dual-core processor is shared between both cores. the cache is shared en therefore both cores can access the same amount of cache memory and can share data in an efficient way. Portanto, minimiza a latência em vez de maximizar.
