四核心問題

好難如實答你
要睇你行乜野software

因部電腦CPU有多核心需要software既配合

比一個實例,我公司有用緊舊既P4機
又有dual core 既機.
我經常幫公司run report (用Microsoft Access 2002),
用D formula 成日都要成分幾兩分鐘先計完
兩部機試出黎既performance dual core 個部真係快唔係好多........
(已經係唔fair 既比試, p4 行緊ddr ram, dual core 個部行緊 dual channel ram.)

再睇CPU 既work load, P4個部 係100% full load,
dual core 個部係50-60%.
再睇seperate 既core work load,
有一個core 係差唔多完全Idle.

呢個test 証明左當你用既software 唔support 多個1個core 既話,
用o係多core CPU電腦只會浪費資源.

Quad core 出左唔耐...相信好多舊既application都唔會support.
所以都要睇你部機將會用乜野application而揀用邊個core.

希望幫倒你:)

you can just look at my question

睇你要佢做咩工作~~
如果係multitasking~~(即係一開開幾十個program去做野...QX6700好d~~)
如果唔係做multitasking~E6800會快d~~
相差幾多multitasking好難計...不過少task的話~剩係計時脈比la~~
(2.93-2.66)/2.66x100%=~10%
