個人認為PiFast仍不太適合作為現代微處理器的效能測試工具.
弟過去曾強調過Super PI在效能測試方面對現代微處理器的"過時性"與"不適用性", 主要原因在於其測量單位過於粗糙 (它是以1秒為單位. 奧運測量人體極限都1/10秒了, 更何況是測高速CPU?). 雖然PiFast測量單位為1/100秒, 但還是不夠精密, 對系統資源亦沒有有效運用及最佳化 (這就是為何有人同一系統下外頻時脈較高, 測量成績反而低的烏龍現象.). 既然版上網友們已漸漸接受Prime95 (在台灣超頻界是可喜的現象), 弟建議不妨多利用它内建的Benchmark功能 (Options -> Benchmark). 值得一提的是它的百萬分之一秒的測量單位, 對現代微處理器及系統資源的最佳化利用, 以及很短的測試時間, 個人相信是目前測CPU穩定度及效能較合適的工具.

看來大哥學有專精！ 一解小弟之前高外頻成績反而低的疑惑！ 感激指教∼   |
