用Prime95來測試電腦的效能
在別篇討論中看見petitdragon兄推薦使用Prime95來替代Super PI測試效能，
在嘗試後覺得很不錯，只要很短的時間內就可完成評測，所以在此介紹給大家。 ^^ ◎測試軟體： Prime95 V.23.7.1 ＊按此下載＊ ◎使用方法： 1. Options -> Benchmark 2. 結果同時也記錄在PRIME95目錄下的result.txt檔案內。 3. 複製在result.txt中測試結果的文字後，就可在此貼文分享了！ ◎測試結果： (以小弟的電腦為列) Intel(R) Pentium(R) 4 CPU 2.40GHz CPU speed: 3808.61 MHz CPU features: RDTSC, CMOV, PREFETCH, MMX, SSE, SSE2 L1 cache size: 8 KB L2 cache size: 512 KB L1 cache line size: 64 bytes L2 cache line size: 128 bytes TLBS: 64 Prime95 version 23.7, RdtscTiming=1 Best time for 384K FFT length: 9.354 ms. Best time for 448K FFT length: 11.116 ms. Best time for 512K FFT length: 12.656 ms. Best time for 640K FFT length: 15.115 ms. Best time for 768K FFT length: 18.385 ms. Best time for 896K FFT length: 21.830 ms. Best time for 1024K FFT length: 24.471 ms. Best time for 1280K FFT length: 32.121 ms. Best time for 1536K FFT length: 39.618 ms. Best time for 1792K FFT length: 46.920 ms. Best time for 2048K FFT length: 53.017 ms. 由以上資料可以看出是以P4 2.4G在3.8G頻率下測試， 比較最後的結果53.017 ms即可了解系統效能了。 精密度0.001ms(毫秒)，不需要貼圖就可分享測試結果，真方便！ 註：若是測試失敗代表您的系統不夠穩定，請降頻後再測試。 |

Intel(R) Pentium(R) 4 CPU 2.40GHz

Best time for 1792K FFT length: 77.709 ms. Best time for 2048K FFT length: 87.769 ms. 新版(23.71)的似乎比較快，或有最佳化？或是其他不同？ 一樣的機器，舊版(21.41)的成績如下 Best time for 256K FFT length: 9.970 ms. Best time for 320K FFT length: 13.336 ms. Best time for 384K FFT length: 16.206 ms. Best time for 448K FFT length: 19.483 ms. Best time for 512K FFT length: 21.745 ms.

我猜應該是P4的記憶體頻寬大 所以佔優勢 另外可以到這裏下載 http://www.mersenne.org/freesoft.htm |
