1).簡介

NXP iMX8已經正式發布，相較于之前NXP i.MX系列的主力產品iMX6，其性能有了大幅提升，本文就針對網絡接口對NXP? iMX8和iMX6兩款ARM處理器進行對比測試。

本文演示所使用的ARM平臺來自Toradex基于NXP iMX8 SoC的Apalis iMX8 ARM核心板和基于NXP iMX6Q SoC的Apalis iMX6 ARM核心板。

2).準備

a). Apalis iMX8QM ARM核心版配合Apalis Evaluation Board載板，Apalis iMX8QM安裝Toradex V3.0b2 Linux demo image，同時連接調試串口UART1(載板X29)到開發主機方便調試。更多關于Apalis iMX8配合Apalis Evaluation Board載板的說明請參考Datasheet和開發上手指南。

b). Apalis iMX6Q ARM核心版配合Apalis Evaluation Board載板，Apalis iMX6Q安裝Toradex V2.8 Linux demo image，同時連接調試串口UART1(載板X29)到開發主機方便調試。更多關于Apalis iMX6配合Apalis Evaluation Board載板的說明請參考Datasheet和開發上手指南。

c). Ubuntu linux PC主機， 用于分別和Apalis iMX8、Apalis iMX6進行收發測試。

d). 測試工具軟件使用 iperf3 工具，Toradex Linux demo image里面已經默認集成，Ubuntu 系統(這里以18.04為例)要通過apt命令來安裝iperf3

----------------------

$ sudo apt update

$ sudo apt install iperf3

----------------------

e). 網絡連接拓撲為Apalis iMX8QM、Apalis iMX6Q以及Ubuntu PC都通過千兆有線網絡連接到同一個局域網。

3). TCP網絡傳輸性能測試對比

a). Apalis iMX6Q/Apalis iMX8QM作為Server端接收，Ubuntu PC作為Client端發送測試

5).總結

本文對比測試了NXP iMX6和NXP iMX8處理器的網絡性能，對于iMX6，由于這個Eratta的限制，400Mb/s左右的性能也就把符合文檔的描述，iMX8則在大多數情況下能夠接近千兆帶寬。
