小弟用了2台試了一下....看來這個程式偏愛INTEL喔

由這個數據來看，Prime95並不適合拿來當效能測試程式，所有的效能測試程式以及用商用軟體實測都顯示P4 Celeron效能其差無比，也足以證明平常跑應用程式，賽揚的表現會最差(這點不會有人懷疑吧) 而Prime95測出的數據竟然是Celeron2.0勝過XP2400.... 因此弟認為Prime95拿來當穩定度測試可以，拿來測效能→無法反應真實狀況，不恰當且不適合！ |

嗯！弟亦認為實用為主才是重點.... |

的確不太適合反應"效能" 因為Prime95似乎真的是跟大頻寬有關聯,跟SEE2 的支援度上倒是還好吧...因為我使用 A64 3000+ 測試的結果也是只比 AthlonXP 3200+(200x11)好上一些罷了.......跟 P4 800 比起來還是輸(A64可是也支援所謂的SEE2指令集的:think: ) 所以誰的頻寬粗在 Prime95之下就佔優勢了(A64依然是單通道設計)
但是以整體能力 例如 3D Mark2001 來說 A64 3000+的成績卻可跟 P4 3G抗衡:) |

Athlon 64 3000+的PR值，大家應該都沒有意見才對:)，但是"Athlon 3000+"就必須給個 :jolin: 。 |

Best time for 1792K FFT length: 171.482 ms. Best time for 2048K FFT length: 197.414 ms. 而且我的背景還有跑騾子,FTP server和一堆有的沒的10幾個程式 會差在哪裡呢??1667居然比2000快?? 我猜這程式不只對sse2最佳化 而是對整個P4的Netbrust架構最佳化 至於A64會輸 我猜是因為還沒有最佳化的關係 |
