測試完 CPU 後，接下來我們再對記憶體進行測試，這次使用的測試軟體還是 **SysBench** ，分別對 [Zero 2W](https://www.digikey.tw/zh/products/detail/raspberry-pi/SC1176/15298147)、[PI3B+](https://www.digikey.tw/zh/products/detail/raspberry-pi/SC0073/8571724)、[PI4](https://www.digikey.tw/zh/products/filter/%E5%8D%95%E6%9D%BF%E8%AE%A1%E7%AE%97%E6%9C%BA-sbc/933?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAPZQDaIAHAJwAMA7FSALoC%2BLhATGSIIgWgycGA%2BW2YsgA) 和 [PI5](https://www.digikey.tw/zh/products/filter/%E5%8D%95%E6%9D%BF%E8%AE%A1%E7%AE%97%E6%9C%BA-sbc/933?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAPZQDa4YAnAOxUgC6Avo4QExkiCIFoMnBgfLYOMgA)，這4塊 Raspberry Pi 記憶體的讀寫進行測試，使用到的測試​​指令如下：

> _sysbench memory --threads=4 --memory-block-size=1K --memory-total-size=2G --memory-oper=read run_  
> _sysbench memory --threads=4 --memory-block-size=1K --memory-total-size=2G --memory-oper=write run_

| 型號 | RAM |
| --- | --- |
| **PI 5** | LPDDR4X-4267 SDRAM (2GB/4GB/8GB) |
| **PI 4B** | LPDDR4-3200 SDRAM(2GB/4GB/8GB) |
| **PI 3B+** | 1GB LPDDR2 SDRAM |
| **PI Zero 2W** | 512MB LPDDR2 |

讀寫測試結果如下所示。從 **圖表一** 中，我們可以很明顯的看到各個 Raspberry Pi 之間記憶體讀寫速度的差距，PI5 依舊遙遙領先，記憶體的效能最高，資料傳輸的速度也是最快的。
