    四核CPU怎么樣

      當今,四核CPU無論是在媒體還是在電子產品賣場,四核CPU的廣告和宣傳都讓人應接不暇,成為了CPU發展的主流方向,但實際上四核CPU的頻率是低于二核CPU頻率,但又是什么樣的優勢讓他能夠站領兩核CPU的市場,成為主流方向,電子產品的寵兒,現在就隨學習啦系哦啊變一起來了解個中因由。

      知己知彼百戰百勝,想要了解其中的原因,讓我們我們先來認識一下四核CPU。四核處理器是整合了四個物理處理器核心。相比雙核心系統,在高負載情況下四核計算機的耗電與熱度要略高,但在正常情況下大多數四核CPU的功耗要低于雙核CPU的功耗,還會獲得較高的性能提升。多核CPU解決方案針對企業管理者們一直尋求增進性能而不用提高實際硬件覆蓋區的需求,提供了不需要增大能量或實際空間的一個方法。

    四核CPU怎么樣

      另一方面,四核CPU是說兩個兩核CPU核心被集成到了一塊芯片上了,但如果四個處理核心的構架方式不同的話,即使說是四核,在處理性能上也是有很大差別的。比如最初的四核相對來說處理性能并不是很高,因為他們是相互獨立分用緩存,四個處理核心之間不能實現相互的信息的共享。但現在最新的四核心處理器是共用緩存的,處理能力和速度要好的多,四個處理核心之間能夠實現信息交流,處理頻率也不可以與現在雙核的處理器做簡單的相比。 四核的CPU就是有四個處理核心的CPU,制造時的倍頻和外頻共同制約著他的頻率。即CPU頻率=倍頻X外頻,四核心分為真四核與假四核,其實,假四核是雙核四線程,例如I3、I5就是假四核,I7才是真四核。

      四核CPU的優勢就好比,同一件事兩個能力相對低的人做和一個能力高的人做,結果當然是2個能力相對低的人做要快的多,就是俗話說的:“三個臭皮匠頂個諸葛亮”。四核CPU處理能力就是分批處理文件的能力, 所以,雖然四核比雙核的頻率低,但是并不表明其處理速度與處理能力不行。

      四核CPU具有超強的性能來保障多種任務的運行、為創建數字內容提供了很好的性能保障,是游戲機、高端模型機的必備裝備,但是平板電腦幾乎用不到四核。目前,Intel和AMD都已經對筆記本電腦發布了四核處理器。但是有專業人士調查發現,購買筆記本的客戶更加看重是更大容量的電池和低功耗。
