NXP iMX8系列處理器核心性能對比測試

By Toradex秦海

1).?簡介

NXP iMX8系列ARM處理器是NXP近幾年新發(fā)布的產(chǎn)品，架構(gòu)均升級到了64bit的ARMv8，其中包含了iMX8，iMX8x，iMX8M Mini，iMX8M Plus等一系列處理器，其基本參數(shù)屬性的對比可以參考下面來自于NXP官網(wǎng)的表格，而本文就從CPU核心、GPU核心、內(nèi)存性能等幾個方面對于iMX8系列的不同產(chǎn)品做一個簡單對比測試供參考。需要注意的是Benchmark測試無法做到絕對完整客觀，通常和軟硬件系統(tǒng)配置以及所采用的Benchmark工具有很大的相關性，不同配置或工具可能得出不同結(jié)論，因此本文的測試只是基于本文測試環(huán)境以及所用Benchmark工具的參考數(shù)據(jù)。







本文所采用的全部測試平臺均來自于Toradex iMX8?系列ARM核心板和對應載板。



2).?準備

a).?Apalis iMX8QM?4GB?WB ITARM核心版配合Ioxra?載板，連接調(diào)試串口UART1（載板X22）到開發(fā)主機方便調(diào)試。

b).?Colibri iMX8QXP 2GB WB ITARM核心板配合Colibri Evaluation Board載板，連接調(diào)試串口UART1（載板X27）到開發(fā)主機方便調(diào)試。

c).?Verdin iMX8M Mini Quad 2GB WB ITARM核心板配合Verdin Development Board載板，連接調(diào)試串口UART1（載板X66）到開發(fā)主機方便調(diào)試。

d).?Verdin iMX8M Plus Quad 4GB WB ITARM核心板配合Verdin Development Board載板，連接調(diào)試串口UART1（載板X66）到開發(fā)主機方便調(diào)試。



3).?預設軟件測試環(huán)境

a).?所有測試模塊均更新為Toradex?Ycoto Linux Reference Multimedia Image5.3.0 Quarterly?版本。


b).?參考這里的說明在Linux下將所有測試模塊的CPU核心工作模式設置為?”performance”，也就是持續(xù)運行在最高主頻。

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

$ echo performance > /sys/devices/system/cpu/<cpux>/cpufreq/scaling_governor

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



4).?CPU單核性能對比測試

a).測試工具軟件?nbench，測試Linux BSP自帶


b).測試方法

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

###?進入/usr/bin目錄，因為測試需要NNET.DAT這個文件

$ cd /usr/bin

###?對于Apalis iMX8QM，分別測試A72核心和A53核心

$?taskset -c 4,5 nbench&& taskset -c 0-3 nbench

###?對于其他模塊

$ nbench

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


c).測試結(jié)果

9).?總結(jié)

本文從CPU、GPU、內(nèi)存等幾個方面簡單對NXP iMX8系列嵌入式ARM處理器家族產(chǎn)品進行了一些benchmark測試，從結(jié)果可以看到iMX8QM各方面性能都是非常領先的；iMX8X強調(diào)功耗性能比，非常均衡；iMX8M Mini和iMX8M Plus在CPU方面基本相當，GPU則是iMX8M Plus領先巨大，同時iMX8M Plus還擁有一個神經(jīng)網(wǎng)絡算法加速的NPU核心，綜合下來iMX8M Plus性能還是好于iMX8M Mini。
