接續上一篇 sysbench CPU benchmark of different AWS EC2 instances ，這邊改用 Geekbench 來做效能測試，Geekbench 是跨平台的效能測試工具，有支援 Windows、Linux、macOS、Android 和 iOS 等系統，測試環境、比較對象和上一篇相同。

測試環境

• Ubuntu: 18.04.3 LTS
• Linux kernel: 4.15.0-1052-aws
• Geekbenck: 5.0.3

比較對象

• General purpose
  • T2
  • T3
  • T3a
  • M4
  • M5
  • M5a
• Compute optimized
  • C4
  • C5
• Memory optimized
  • R4
  • R5
  • R5a

T 系列的機器也都同樣是開 Unlimited Mode 下去跑測試讓 CPU 可以全速運轉

執行時不用特別帶參數，像下面這樣

測試畫面

$ ./Geekbench-5.0.3-Linux/geekbench5 
Geekbench 5.0.3 Tryout : https://www.geekbench.com/

Geekbench 5 is in tryout mode.

Geekbench 5 requires an active Internet connection when in tryout mode, and 
automatically uploads test results to the Geekbench Browser. Other features 
are unavailable in tryout mode.

Buy a Geekbench 5 license to enable offline use and remove the limitations of 
tryout mode.

If you would like to purchase Geekbench you can do so online:

If you have already purchased Geekbench, enter your email address and license 
key from your email receipt with the following command line:

  ./Geekbench-5.0.3-Linux/geekbench5 -r <email address> <license key>

測試結果

接著看測試結果，免費版的 Geekbench 測試時必須要有網路連線，結果不會直接顯示在本機，要上傳到他們的伺服器上看，好處應該是比較不怕造假（假設有對資料做應該有的基本驗證機制）或弄錯，畫面呈現如下，除了效能測試的分數以外，也一些作業系統、CPU、記憶體等資訊：
