CPU的速度問題,,,,,,,

Hello~!
GHz的計算方法: 3000MHz = 3GHz
其實要知一隻CPU快定慢? 有幾點要留意. 第1)CPU有多Hz? 例如3.0GHz比2.8GHz快. 第2)CPU的外頻行多小? 例如分別有三隻3.2GHz的CPU, 第一隻係外頻行400 X 8倍頻 = 3200. 第二隻係外頻行533 X 6倍頻 = 3198. 第三隻係外頻行800 X 4倍頻 = 3200. 第3)看CPU支援32bit定64bit? 第4)CPU的L2 cache有多小MB? MB數越多, 運算資料越流暢. 第5)CPU的品牌? 每個CPU品牌支援技術都有不同, 這個要看使用軟件是否支援CPU技術?
註: CPU還需要配合主機板和RAM, 才能發揮效能~!
希望能夠幫到你~!

although 2.2GHz is mean the speed, but it not all. there are many other thing affect the speed. for example,Pentium Dual-Core E2140 only has 1.6GHz, but it maybe faster than Pentium4 3.8GHz.But if two CPU is same in other place, of course higher speed, run faster.
2MB is refer to the L2 chace. you can think that chace is the ram in CPU, it store the thing that CPU need, if CPU can't find thing in chace, it will go to ram to find.in fact that, ram is much slower than chace.

速度無錯係一個快慢的因素,但不代表一定快好多,Intel 2 MB 緩存記憶體就一定比 AMD 嘅640KB 大和存取快些,這部份亦都係快慢嘅一個要素, 但整體來說,除非你真係用百分一秒計時來計它有多快,否則一般使用者察覺不出來的,客觀點說,除非你好 mind 咁用 3D Mark去計分,又或者你係一個超頻發燒友! 否則對你影响不大！L 2 Cache 必定是越大就越貴, 所以 Pentium 必定比 Celeron 貴, (L 2 Cache 大小的分別 ) 而且快和慢仲要睇埋塊底塊 FSB 有幾多, 加埋條 RAM 係咪行 Dual Channel.........所以都係嗰句就0.2來說, 分別不大!
