根據以下這個網站的資料發現比較新的t6570的效能竟然比較舊型的t4400的效能還差，為什麼會如此呢?

至於 Pentium Dual-Core T4400 : http://ark.intel.com/Product.aspx?id=40739&processor=T4400&spec-codes=SLGJL
根據比較的結果, 技術規格如下 :

另外, 還有一個 Execute Disable Bit , 兩個都是 Yes.
簡單來說, 兩個都是 64 Bit 雙核心的處理器, 兩個都沒有 Turbo Booster ; 若沒有用到 Intel 虛擬化技術的前提下, 差異幅度可以說是很有限.
以上表格, 是小弟去 Intel 官方網站比的比較表查詢出來的結果....
另外, 根據 Notebookcheck 的評鍵, Pentium Dual-Core T4400 的評比確實是比 Core2Duo T6570 好.
