4 core vs 2 core

Even more and more 4 core CPUs are on the market, I was told there are not many programs actually can take advantage of all 4 cores. If this is true, does it mean 4 core CPU is no much better and a high clock speed 2 core (at least for now)?

所有跟帖： 

• 完全正確。多核處理器隻有在並行計算時才有優勢。 -墨鬥魚- ♀ (258 bytes) () 01/26/2009 postreply 10:57:27

• you don't need parallel algorithm to take advantage -用戶名被占用了- ♂ (192 bytes) () 01/26/2009 postreply 11:32:04

• 你說的是讓一台機器同時執行多個互不相幹的獨立任務。 -墨鬥魚- ♀ (190 bytes) () 01/26/2009 postreply 18:27:25

• Mac Pro＋OS X 10.5＋Parallel 算服務器還是個人電腦呢，哈哈 -用戶名被占用了- ♂ (0 bytes) () 01/26/2009 postreply 18:32:21

• 你仔細想想，Mac Pro＋OS X 10.5真的利用多核處理器麽? -墨鬥魚- ♀ (161 bytes) () 01/26/2009 postreply 19:36:42

• 咱們啥時候談過全時全並行計算，不是在談普通PC嘛。答案：是的 -用戶名被占用了- ♂ (0 bytes) () 01/27/2009 postreply 04:02:08

• 換個提法：通過某些技巧安排，完全可以充分利用多core優勢。 -用戶名被占用了- ♂ (0 bytes) () 01/27/2009 postreply 04:03:41

• 個人電腦不太可能有這種情況？ -鯉魚- ♂ (145 bytes) () 01/28/2009 postreply 11:15:53
