Introduction
電腦基準測試測什麼???
CPU:多核處理、單核效能、時脈速度、快取大小等,
常見測試項目有壓縮解壓縮、編碼、數據加密、浮點運算等。
GPU:每秒幀數(FPS)、光線追蹤等影像品質,以及圖形處理效能,
通常使用圖形渲染、遊戲表現及其他與圖像處理相關的任務進行測試。
記憶體性能:評估隨機存取記憶體(RAM)讀寫速度、延遲時間和處理多任務的能力。
儲存性能:測試硬碟(HDD)或固態硬碟(SSD)的讀寫速度和資料傳輸、應用啟動時的表現
整體系統性能:測試整個系統在綜合工作負載下的效能,如影像編輯、影片轉碼、遊戲運行等,產生一個綜合性能得分,方便比較不同電腦系統的性能。
Super π (SuperPI)
現在的CPU通常具有強大的計算能力,但我們仍然可以透過簡單的數學計算來操壞他(?..測試他的能力
super pi 是一款老牌的「CPU 單線程效能、系統穩定性」測試軟體,
透過計算圓周率精確到小數點後3200萬位數(gauss-legendre algorithm),來測試單線程性能
貼心體醒:請使用系統管理員身份執行

super pi wiki:https://zh.wikipedia.org/wiki/Super_PI
如果要測試多核心效能,推薦使用「Hyper PI」。
其他的多執行緒測試工具有:wPrime、IntelBurnTest、Prime95、Montecarlo superPI、OCCT…等軟體
Novabench
測試包括 CPU 速度和顯示卡 (GPU) 速度在內的多項電腦性能指標。
在 GPU 測試方面則包括 Direct3D 和 OpenCL 等的測試。
此外,它還可測試記憶體轉換速度和磁碟讀取速度
載點:https://novabench.com/download
Direct3D
使用GPU幫助遊戲和其他多媒體應用程式進行 3D 圖像處理。
它主要應用於 Windows 平台以及 Xbox 主機
OpenCL
進行異質計算和並行計算,用於需要大規模數據處理或高效能計算的應用。
如科學計算、人工智能、圖像處理等
如果你的電腦中還有正在執行的程式,建議先關閉後再開始進行測試
3D繪圖效能(GPU)的測試,左上角會顯示顯示卡的型號(含記憶體)、測試的解析度及每秒的張數(FPS)

HWMonitor
為硬體監控程序追蹤電腦的重要統計數據,
包括各種組件的溫度和當前輸入電壓。
如:CPU 的電壓、CPU 風扇轉速、CPU 溫度、顯示卡溫度以及硬碟溫度。
若您擔心電腦可能過熱或是覺得風扇運作不太正常,那麼就可以透過這款軟體來幫您隨時做監控 有了這些訊息,
您可以確保您的機器不存在過熱或任何其他類型的機械故障。

VGA 壓力測試(顯示卡老化測試)(顯卡燒機測試)以及 OpenGL 基準測試例如很多人想知道自己的顯卡遊戲可以跑幾幀(FPS),檢測一下就出來了
想知道顯卡的穩定性也可以直接用這個程式,顯卡如果有問題,應該撐不到30分鐘就會跳出或破圖
顯卡如果正常,你就算連續燒12小時也OK不會怎樣
貼心小提示 : 如果自己玩燒太久,出問題後果自負

Learn More →大部份的使用者的螢幕是FHD(1920*1080),如果你的螢幕是2K或4K,一樣在Resolution這邊選擇
按鍵盤上的ESC中斷,一般你只要燒個20~30分鐘,如果都沒有跳出,那就是正常。
如果有問題會跳出軟體、藍屏或黑屏、甚至直接當機(畫面凍結)都有可能。
燒顯卡的溫度,不好說,一般來說60~90度都有可能。
