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>

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：
